Prevents an infinite loop with malformed UNCs and/or permission problems.

would crash (common.register wouldn't be instantiated yet). Now plugins can be

Subject: [PATCH 039/338] Get pipe tests running on Windows. (#550)

* Get pipe tests running on Windows.

I used the FIND command which ships with Windows as something to
pass data through.

The test checks that a POSIX-like find(1) exists and skips the tests
if this condition is true because Windows-provided FIND is incompatible
with find(1).

* Remove obvious comments.

Requested by @nfischer. I removed both the unix-specific and Windows
specific comments because I figure they both fall under being too
obvious based on being in the process.platform conditional.

* Make FIND usage cleaner and document it.

* Use shx grep to make pipe tests portable.

Discussed in #550. To test piping and its interaction with
real processes, a shellout is necessary. But on Windows,
you cannot rely on utilities like grep(1) being around.
Using shx, we can write portable code. Otherwise, the
tests have to be conditional on the platform and be
way more complicated.

Subject: [PATCH 040/338] fix: maxdepth doesn't limit total number of copies
 (#549)

* fix: maxdepth doesn't limit total number of copies

Prevent maxdepth from limiting the total number of copies, only allow it to
limit the maximum depth

Fixes #547

* refactor: make `depth` be its own argument

Subject: [PATCH 042/338] fix: handle code-less errors more carefully in exec
 (#554)

If an error exists, but has no error code, it defaults to 1 (a common code for
most Unix commands). Tests have been omitted since this is an edge case that is
difficult to reproduce.

Fixes #536

Subject: [PATCH 072/338] chore: switch to files attribute from npmignore
 (#613)

Prefer the `files` attribute over `.npmignore` to minimize the bytes users
download when installing ShellJS. This cuts the size down from ~1.8M to ~1.2M.

Subject: [PATCH 084/338] refactor: list all commands in commands.json (#616)

* refactor: list all commands in commands.json

This also changes the order of commands in the docs, due to how I changed
the doc-generating script.

* fix lint error and alphabetize command list

-Returns array of files in the given path, or in current directory if no path provided.
+Available options:
 
++ `-v`: output a diagnostic for every file processed
++ `-c`: like verbose but report only when a change is made
++ `-R`: change files and directories recursively
 
-### find(path [, path ...])
-### find(path_array)
 Examples:
 
 ```javascript
-find('src', 'lib');

-find('.').filter(function(file) { return file.match(/\.js$/); });
+chmod(755, '/Users/brandon');
+chmod('755', '/Users/brandon'); // same as above
+chmod('u+x', '/Users/brandon');
 ```
 
-Returns array of all files (however deep) in the given paths.
+Alters the permissions of a file or directory by either specifying the
+absolute permissions in octal form or expressing the changes in symbols.
+This command tries to mimic the POSIX behavior as much as possible.
+Notable exceptions:
 
-The main difference from `ls('-R', path)` is that the resulting file names
-include the base directories, e.g. `lib/resources/file1` instead of just `file1`.
++ In symbolic modes, 'a-r' and '-r' are identical.  No consideration is
+  given to the umask.
++ There is no "quiet" option since default behavior is to run silent.

 Copies files.
 
 
-### rm([options,] file [, file ...])
-### rm([options,] file_array)
+### pushd([options,] [dir | '-N' | '+N'])
+
 Available options:
 
-+ `-f`: force
-+ `-r, -R`: recursive
++ `-n`: Suppresses the normal change of directory when adding directories to the stack, so that only the stack is manipulated.
+
+Arguments:
+
++ `dir`: Makes the current working directory be the top of the stack, and then executes the equivalent of `cd dir`.
++ `+N`: Brings the Nth directory (counting from the left of the list printed by dirs, starting with zero) to the top of the list by rotating the stack.
++ `-N`: Brings the Nth directory (counting from the right of the list printed by dirs, starting with zero) to the top of the list by rotating the stack.
 
 Examples:
 
 ```javascript
-rm('-rf', '/tmp/*');
-rm('some_file.txt', 'another_file.txt');
-rm(['some_file.txt', 'another_file.txt']); // same as above
+// process.cwd() === '/usr'
+pushd('/etc'); // Returns /etc /usr
+pushd('+1');   // Returns /usr /etc
 ```
 
-Removes files.
+Save the current directory on the top of the directory stack and then cd to `dir`. With no arguments, pushd exchanges the top two directories. Returns an array of paths in the stack.
 
+### popd([options,] ['-N' | '+N'])
 
-### mv([options ,] source [, source ...], dest')
-### mv([options ,] source_array, dest')
 Available options:
 
-+ `-f`: force (default behavior)
-+ `-n`: no-clobber
++ `-n`: Suppresses the normal change of directory when removing directories from the stack, so that only the stack is manipulated.
+
+Arguments:
+
++ `+N`: Removes the Nth directory (counting from the left of the list printed by dirs), starting with zero.
++ `-N`: Removes the Nth directory (counting from the right of the list printed by dirs), starting with zero.
 
 Examples:
 
 ```javascript
-mv('-n', 'file', 'dir/');
-mv('file1', 'file2', 'dir/');
-mv(['file1', 'file2'], 'dir/'); // same as above

+echo(process.cwd()); // '/etc'
+popd();              // '/usr'
+echo(process.cwd()); // '/usr'
 ```
 
-Moves files.
+When no arguments are given, popd removes the top directory from the stack and performs a cd to the new top directory. The elements are numbered from 0 starting at the first directory listed with dirs; i.e., popd is equivalent to popd +0. Returns an array of paths in the stack.
 
+### dirs([options | '+N' | '-N'])
 
-### mkdir([options,] dir [, dir ...])
-### mkdir([options,] dir_array)
 Available options:
 
-+ `-p`: full path (will create intermediate dirs if necessary)
++ `-c`: Clears the directory stack by deleting all of the elements.
 
-Examples:
+Arguments:
 
-```javascript
-mkdir('-p', '/tmp/a/b/c/d', '/tmp/e/f/g');
-mkdir('-p', ['/tmp/a/b/c/d', '/tmp/e/f/g']); // same as above

++ `+N`: Displays the Nth directory (counting from the left of the list printed by dirs when invoked without options), starting with zero.
++ `-N`: Displays the Nth directory (counting from the right of the list printed by dirs when invoked without options), starting with zero.
 
-Creates directories.
+Display the list of currently remembered directories. Returns an array of paths in the stack, or a single path if +N or -N was specified.
 
+See also: pushd, popd
 
-### test(expression)
-Available expression primaries:
 
-+ `'-b', 'path'`: true if path is a block device
-+ `'-c', 'path'`: true if path is a character device
-+ `'-d', 'path'`: true if path is a directory
-+ `'-e', 'path'`: true if path exists
-+ `'-f', 'path'`: true if path is a regular file
-+ `'-L', 'path'`: true if path is a symbolic link
-+ `'-p', 'path'`: true if path is a pipe (FIFO)
-+ `'-S', 'path'`: true if path is a socket
+### echo([options,] string [, string ...])
+Available options:
+
++ `-e`: interpret backslash escapes (default)
 
 Examples:
 
 ```javascript
-if (test('-d', path)) { /* do something with dir */ };
-if (!test('-f', path)) continue; // skip if it's a regular file
+echo('hello world');
+var str = echo('hello world');
 ```
 
-Evaluates expression using the available primaries and returns corresponding value.
+Prints string to stdout, and returns string with additional utility methods
+like `.to()`.
 
 
-### cat(file [, file ...])
-### cat(file_array)
+### exec(command [, options] [, callback])
+Available options (all `false` by default):
+
++ `async`: Asynchronous execution. If a callback is provided, it will be set to
+  `true`, regardless of the passed value.
++ `silent`: Do not echo program output to console.
++ and any option available to NodeJS's
+  [child_process.exec()](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback)
 
 Examples:
 
 ```javascript
-var str = cat('file*.txt');
-var str = cat('file1', 'file2');
-var str = cat(['file1', 'file2']); // same as above
+var version = exec('node --version', {silent:true}).stdout;
+
+var child = exec('some_long_running_process', {async:true});
+child.stdout.on('data', function(data) {
+  /* ... do something with data ... */
+});
+
+exec('some_long_running_process', function(code, stdout, stderr) {
+  console.log('Exit code:', code);
+  console.log('Program output:', stdout);
+  console.log('Program stderr:', stderr);
+});
 ```
 
-Returns a string containing the given file, or a concatenated string
-containing the files if more than one file is given (a new line character is
-introduced between each file).
+Executes the given `command` _synchronously_, unless otherwise specified.  When in synchronous
+mode, this returns a ShellString (compatible with ShellJS v0.6.x, which returns an object
+of the form `{ code:..., stdout:... , stderr:... }`). Otherwise, this returns the child process
+object, and the `callback` gets the arguments `(code, stdout, stderr)`.
 
+Not seeing the behavior you want? `exec()` runs everything through `sh`
+by default (or `cmd.exe` on Windows), which differs from `bash`. If you
+need bash-specific behavior, try out the `{shell: 'path/to/bash'}` option.
 
-### head([{'-n': \<num\>},] file [, file ...])
-### head([{'-n': \<num\>},] file_array)
-Available options:
+**Note:** For long-lived processes, it's best to run `exec()` asynchronously as
+the current synchronous implementation uses a lot of CPU. This should be getting
+fixed soon.
 
-+ `-n <num>`: Show the first `<num>` lines of the files
 
+### find(path [, path ...])
+### find(path_array)
 Examples:
 
 ```javascript
-var str = head({'-n': 1}, 'file*.txt');
-var str = head('file1', 'file2');
-var str = head(['file1', 'file2']); // same as above
+find('src', 'lib');
+find(['src', 'lib']); // same as above
+find('.').filter(function(file) { return file.match(/\.js$/); });
 ```
 
-Read the start of a file.
+Returns array of all files (however deep) in the given paths.
+
+The main difference from `ls('-R', path)` is that the resulting file names
+include the base directories, e.g. `lib/resources/file1` instead of just `file1`.
 
 
-### tail([{'-n': \<num\>},] file [, file ...])
-### tail([{'-n': \<num\>},] file_array)
+### grep([options,] regex_filter, file [, file ...])
+### grep([options,] regex_filter, file_array)
 Available options:
 
-+ `-n <num>`: Show the last `<num>` lines of the files
++ `-v`: Inverse the sense of the regex and print the lines not matching the criteria.
++ `-l`: Print only filenames of matching files
 
 Examples:
 
 ```javascript
-var str = tail({'-n': 1}, 'file*.txt');
-var str = tail('file1', 'file2');
-var str = tail(['file1', 'file2']); // same as above
+grep('-v', 'GLOBAL_VARIABLE', '*.js');
+grep('GLOBAL_VARIABLE', '*.js');
 ```
 
-Read the end of a file.
-
-
-### ShellString.prototype.to(file)
-
-Examples:
-
-```javascript
-cat('input.txt').to('output.txt');
-```
+Reads input string from given files and returns a string containing all lines of the
+file that match the given `regex_filter`.
 
-Analogous to the redirection operator `>` in Unix, but works with
-ShellStrings (such as those returned by `cat`, `grep`, etc). _Like Unix
-redirections, `to()` will overwrite any existing file!_
 
+### head([{'-n': \<num\>},] file [, file ...])
+### head([{'-n': \<num\>},] file_array)
+Available options:
 
-### ShellString.prototype.toEnd(file)
++ `-n <num>`: Show the first `<num>` lines of the files
 
 Examples:
 
 ```javascript
-cat('input.txt').toEnd('output.txt');
+var str = head({'-n': 1}, 'file*.txt');
+var str = head('file1', 'file2');
+var str = head(['file1', 'file2']); // same as above
 ```
 
-Analogous to the redirect-and-append operator `>>` in Unix, but works with
-ShellStrings (such as those returned by `cat`, `grep`, etc).
+Read the start of a file.
 
 
-### sed([options,] search_regex, replacement, file [, file ...])
-### sed([options,] search_regex, replacement, file_array)
+### ln([options,] source, dest)
 Available options:
 
-+ `-i`: Replace contents of 'file' in-place. _Note that no backups will be created!_
++ `-s`: symlink
++ `-f`: force
 
 Examples:
 
 ```javascript
-sed('-i', 'PROGRAM_VERSION', 'v0.1.3', 'source.js');
-sed(/.*DELETE_THIS_LINE.*\n/, '', 'source.js');
+ln('file', 'newlink');
+ln('-sf', 'file', 'existing');
 ```
 
-Reads an input string from `files` and performs a JavaScript `replace()` on the input
-using the given search regex and replacement string or function. Returns the new string after replacement.
-
-Note:
-
-Like unix `sed`, ShellJS `sed` supports capture groups. Capture groups are specified
-using the `$n` syntax:
-
-```javascript
-sed(/(\w+)\s(\w+)/, '$2, $1', 'file.txt');
-```
+Links source to dest. Use -f to force the link, should dest already exist.
 
 
-### sort([options,] file [, file ...])
-### sort([options,] file_array)
+### ls([options,] [path, ...])
+### ls([options,] path_array)
 Available options:

++ `-d`: list directories themselves, not their contents
++ `-l`: list objects representing each file, each with fields containing `ls
+        -l` output fields. See
+        [fs.Stats](https://nodejs.org/api/fs.html#fs_class_fs_stats)

+ls('-R', ['/users/me', '/tmp']); // same as above
+ls('-l', 'file.txt'); // { name: 'file.txt', mode: 33188, nlink: 1, ...}
 ```
 
-Return the contents of the files, sorted line-by-line. Sorting multiple
-files mixes their content, just like unix sort does.
+Returns array of files in the given path, or in current directory if no path provided.
 
 
-### uniq([options,] [input, [output]])
+### mkdir([options,] dir [, dir ...])
+### mkdir([options,] dir_array)
 Available options:
 
-+ `-i`: Ignore case while comparing
-+ `-c`: Prefix lines by the number of occurrences
-+ `-d`: Only print duplicate lines, one for each group of identical lines
++ `-p`: full path (will create intermediate dirs if necessary)
 
 Examples:
 
 ```javascript

-### grep([options,] regex_filter, file_array)
+### mv([options ,] source [, source ...], dest')
+### mv([options ,] source_array, dest')
 Available options:
 
-+ `-v`: Inverse the sense of the regex and print the lines not matching the criteria.
-+ `-l`: Print only filenames of matching files
++ `-f`: force (default behavior)
++ `-n`: no-clobber
 
 Examples:
 
 ```javascript
-grep('-v', 'GLOBAL_VARIABLE', '*.js');
-grep('GLOBAL_VARIABLE', '*.js');
+mv('-n', 'file', 'dir/');
+mv('file1', 'file2', 'dir/');
+mv(['file1', 'file2'], 'dir/'); // same as above
 ```
 
-Reads input string from given files and returns a string containing all lines of the
-file that match the given `regex_filter`.
+Moves files.

-var str = echo('hello world');
+sed('-i', 'PROGRAM_VERSION', 'v0.1.3', 'source.js');
+sed(/.*DELETE_THIS_LINE.*\n/, '', 'source.js');
 ```
 
-Prints string to stdout, and returns string with additional utility methods
-like `.to()`.
+Reads an input string from `files` and performs a JavaScript `replace()` on the input
+using the given search regex and replacement string or function. Returns the new string after replacement.
 
+Note:
 
-### pushd([options,] [dir | '-N' | '+N'])
+Like unix `sed`, ShellJS `sed` supports capture groups. Capture groups are specified
+using the `$n` syntax:
 
-Available options:
+```javascript
+sed(/(\w+)\s(\w+)/, '$2, $1', 'file.txt');

-When no arguments are given, popd removes the top directory from the stack and performs a cd to the new top directory. The elements are numbered from 0 starting at the first directory listed with dirs; i.e., popd is equivalent to popd +0. Returns an array of paths in the stack.
+Return the contents of the files, sorted line-by-line. Sorting multiple
+files mixes their content, just like unix sort does.
 
-### dirs([options | '+N' | '-N'])
 
+### tail([{'-n': \<num\>},] file [, file ...])
+### tail([{'-n': \<num\>},] file_array)
 Available options:
 
-+ `-c`: Clears the directory stack by deleting all of the elements.
-
-Arguments:
-
-+ `+N`: Displays the Nth directory (counting from the left of the list printed by dirs when invoked without options), starting with zero.
-+ `-N`: Displays the Nth directory (counting from the right of the list printed by dirs when invoked without options), starting with zero.
++ `-n <num>`: Show the last `<num>` lines of the files
 
-Display the list of currently remembered directories. Returns an array of paths in the stack, or a single path if +N or -N was specified.
+Examples:
 
-See also: pushd, popd
+```javascript
+var str = tail({'-n': 1}, 'file*.txt');
+var str = tail('file1', 'file2');
+var str = tail(['file1', 'file2']); // same as above
+```
 
+Read the end of a file.
 
-### ln([options,] source, dest)
-Available options:
 
-+ `-s`: symlink
-+ `-f`: force
+### tempdir()
 
 Examples:
 
 ```javascript
-ln('file', 'newlink');
-ln('-sf', 'file', 'existing');
+var tmp = tempdir(); // "/tmp" for most *nix platforms
 ```
 
-Links source to dest. Use -f to force the link, should dest already exist.
-
-
-### exit(code)
-Exits the current process with the given exit code.
+Searches and returns string containing a writeable, platform-dependent temporary directory.
+Follows Python's [tempfile algorithm](http://docs.python.org/library/tempfile.html#tempfile.tempdir).
 
-### env['VAR_NAME']
-Object containing environment variables (both getter and setter). Shortcut to process.env.
 
-### exec(command [, options] [, callback])
-Available options (all `false` by default):
+### test(expression)
+Available expression primaries:
 
-+ `async`: Asynchronous execution. If a callback is provided, it will be set to
-  `true`, regardless of the passed value.
-+ `silent`: Do not echo program output to console.
-+ and any option available to NodeJS's
-  [child_process.exec()](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback)
++ `'-b', 'path'`: true if path is a block device
++ `'-c', 'path'`: true if path is a character device
++ `'-d', 'path'`: true if path is a directory
++ `'-e', 'path'`: true if path exists
++ `'-f', 'path'`: true if path is a regular file
++ `'-L', 'path'`: true if path is a symbolic link
++ `'-p', 'path'`: true if path is a pipe (FIFO)
++ `'-S', 'path'`: true if path is a socket
 
 Examples:
 
 ```javascript
-var version = exec('node --version', {silent:true}).stdout;
-
-var child = exec('some_long_running_process', {async:true});
-child.stdout.on('data', function(data) {
-  /* ... do something with data ... */
-});
-
-exec('some_long_running_process', function(code, stdout, stderr) {
-  console.log('Exit code:', code);
-  console.log('Program output:', stdout);
-  console.log('Program stderr:', stderr);
-});
+if (test('-d', path)) { /* do something with dir */ };
+if (!test('-f', path)) continue; // skip if it's a regular file
 ```
 
-Executes the given `command` _synchronously_, unless otherwise specified.  When in synchronous
-mode, this returns a ShellString (compatible with ShellJS v0.6.x, which returns an object
-of the form `{ code:..., stdout:... , stderr:... }`). Otherwise, this returns the child process
-object, and the `callback` gets the arguments `(code, stdout, stderr)`.
+Evaluates expression using the available primaries and returns corresponding value.
 
-Not seeing the behavior you want? `exec()` runs everything through `sh`
-by default (or `cmd.exe` on Windows), which differs from `bash`. If you
-need bash-specific behavior, try out the `{shell: 'path/to/bash'}` option.
 
-**Note:** For long-lived processes, it's best to run `exec()` asynchronously as
-the current synchronous implementation uses a lot of CPU. This should be getting
-fixed soon.
+### ShellString.prototype.to(file)
 
+Examples:
 
-### chmod(octal_mode || octal_string, file)
-### chmod(symbolic_mode, file)
+```javascript
+cat('input.txt').to('output.txt');
+```
 
-Available options:
+Analogous to the redirection operator `>` in Unix, but works with
+ShellStrings (such as those returned by `cat`, `grep`, etc). _Like Unix
+redirections, `to()` will overwrite any existing file!_
 
-+ `-v`: output a diagnostic for every file processed
-+ `-c`: like verbose but report only when a change is made
-+ `-R`: change files and directories recursively
+
+### ShellString.prototype.toEnd(file)
 
 Examples:
 
 ```javascript
-chmod(755, '/Users/brandon');
-chmod('755', '/Users/brandon'); // same as above
-chmod('u+x', '/Users/brandon');
+cat('input.txt').toEnd('output.txt');
 ```
 
-Alters the permissions of a file or directory by either specifying the
-absolute permissions in octal form or expressing the changes in symbols.
-This command tries to mimic the POSIX behavior as much as possible.
-Notable exceptions:
-
-+ In symbolic modes, 'a-r' and '-r' are identical.  No consideration is
-  given to the umask.
-+ There is no "quiet" option since default behavior is to run silent.
+Analogous to the redirect-and-append operator `>>` in Unix, but works with
+ShellStrings (such as those returned by `cat`, `grep`, etc).

@@ -659,37 +651,39 @@ A FILE argument that does not exist is created empty, unless -c is supplied.
 This is a partial implementation of *[touch(1)](http://linux.die.net/man/1/touch)*.
 
 
-### set(options)
+### uniq([options,] [input, [output]])
 Available options:
 
-+ `+/-e`: exit upon error (`config.fatal`)
-+ `+/-v`: verbose: show all commands (`config.verbose`)
-+ `+/-f`: disable filename expansion (globbing)
++ `-i`: Ignore case while comparing
++ `-c`: Prefix lines by the number of occurrences
++ `-d`: Only print duplicate lines, one for each group of identical lines
 
 Examples:

Subject: [PATCH 090/338] chore: set up test coverage (#638)

Use nyc for test coverage and ignore all nyc-related files in git & eslint.
This increases testing time (~35sec -> ~60sec on my 4-core machine).

Subject: [PATCH 091/338] fix: allow non-normalized paths as input to mkdir
 (#635)

Adds tests to make sure that non-normalized paths (i.e. path/to/./dir) are
valid for a few commands, including mkdir() which previously failed when given
the -p flag.

Fixes #634

Subject: [PATCH 105/338] Switch commands.json -> commands.js (#668)

WebPack has issues with importing JSON directly and using JavaScript
methods on it. For this reason, using the `.forEach()` method on the
imported JSON array caused a method-not-found error.

Instead, we can make this a real JavaScript array by keeping it in a
JavaScript file and exporting it as a field.

It should be noted that exporting it as `exports = [...]` does not work,
because Node won't actually interpret it as a JavaScript array (with
the required methods). So instead we can export it as
`exports.list = [...]` and access the `list` field to get the real
JavaScript array of command names.

Fixes #667

Subject: [PATCH 108/338] docs: miscellaneous README changes (#661)

- Add @freitagbr to the bottom of the README
 - Remove docs about shjs (it's not well supported)
 - Remove docs about coffeescript (we don't do anything special for
   coffeescript anyway)
 - Modify the section about shelljs/global, since we strongly recommend
   avoiding this now
 - Rewrite the code example to use `require('shelljs')` instead of
   shelljs/global
 - Mention ESLint next to JSHint
 - Reformat sections with long lines to be 80 columns

Subject: [PATCH 110/338] test: don't count hard-to-test lines for coverage
 (#672)

No change in logic.

Add `/* istanbul ignore next */` lines for hard-to-test lines so that
they don't count against us during code coverage.

I've also adjusted comments that I found confusing, and changed some
formatting.

Subject: [PATCH 111/338] test: add misc. tests to improve coverage (#673)

No change in production logic.

This adds missing tests to improve test coverage. This does not change
ShellJS behavior at all--all test cases are testing already-working
functionality.

One test case has been renamed for clarity.

For the "omit directory if missing recursive flag" case, we were
actually already testing that in another case, but we were testing
multiple things in that test case. It's better to test this one error
condition explicitly in its own case.

When adding real tests for `parseOptions()`, we need to explicitly clear
`common.state.error` because we're testing an internal function, not a
wrapped command.

Partial fix for #671

Subject: [PATCH 114/338] fix: convert error output to be consistent
 cross-platform (#684)

* fix: convert error output to be consistent cross-platform

The error output produced by `shell.error()` or `result.stderr` should
not be inconsistent between platforms. This ensures that path separators
are always printed by ShellJS as `/` instead of as `\` on Windows. This
should allow scripts using ShellJS to be more consistent cross-platform.

We were not previously relying on error output to always be consistent--
only checking its truthiness. Since this was not part of our tested API,
it should be reasonable to change this and release in a patch.

Fixes #681

* Fix broken pushd test case

* Fix TODO in a test case

Subject: [PATCH 117/338] refactor(parseOptions): better handle errors (#674)

* refactor(parseOptions): better handle errors

For the case where `parseOptions()` is passed a string that does not
start with a hyphen, we should reject this string instead of returning
the same value. This has no change on any other test cases, and should
not affect any commands since we are careful about what input we pass to
`parseOptions()`

This also adjust how we were handling error cases in the function. We
were previously using two different calls to `common.error()`, one for
if `errorOptions` is passed, and one without. This hurts readability,
because it reads like "if we have errorOptions, then this is an error,
and if we don't then it's also an error," instead of the more
appropriate, "we reached an error case and should use errorOptions if
it's available, otherwise we should signal an error without using it."

We do not need to use `errorOptions` for the added call to `error()`,
since this is an error which indicates misuse, and should not be
recoverable.

This adds a test case as well, for a line which was not previously
covered in our tests.

Partial fix for #671

* Refactor parseOptions()

This validates input at the top of `parseOptions()` for type
correctness. This changes `typeof x === 'object'` to `x instanceOf
Object` to improve robustness. Now we can safely use `errorOptions`
knowing that if it has a truthy value, it will be an object, otherwise
we should use defaults instead.

The new tests ensure that we have 100% unit test coverage for this
function.

* Use exceptions, not common.error()s, for internal misuse

* Add common.isObject() helper function

The `isObject()` helper is used throughout common.js to reliably test if
variables are JavaScript objects.

Subject: [PATCH 127/338] Properly handle directories as arguments (#713)

* fix(cat): do not cat directories

Fixes #707

* fix(head): do not let head() read directories

Also fixes a typo

* fix(sort): do not sort directories

Also fixes a typo

* fix(tail): do not let tail() read directories

Also fixes a typo

* fix(uniq): do not let uniq() read directories

We also had a test which called sort() instead of uniq(), so we never
actually tested the missing-file case. This fixes that as well.

This also throws an error for using a directory as output.

* fix(pipe): fix breakages with piped commands

Subject: [PATCH 128/338] fix(mkdir): improve error handling around files
 (#721)

* fix(mkdir): improve error handling around files

In particular, this fixes:

 - if we try to overwrite a file with a mkdir
 - if we try to create a subdirectory of a file
 - adds `continue: true` in spots where we missed it

Fixes #720

* Fixing tests on Windows

Subject: [PATCH 142/338] test(head): improve coverage (#743)

This adds a test for `head()` on the right-hand side of a pipe. This also
removes the try-catch surrounding `fs.openSync()`, because it was unreachable
code. `fs.existsSync()` guarantees that the file exists, and `fs.openSync()`
only throws if the file does not exist, according to official documentation.

Fixes #671

Subject: [PATCH 143/338] test(exec): add tests for coverage (#744)

* test(exec): add tests for coverage

No logic change.

This adds one test to cover some missing lines, and adds some `istanbul ignore`
directives.

I see 100% line coverage for `src/exec.js` when running:

```sh
$ nyc --reporter=text --reporter=lcov ava --serial test/exec.js`
```

Fixes #742

* Fix lint

Subject: [PATCH 144/338] chore: add skipOnWin and skipOnUnix test helpers
 (#746)

This adds `skipOnWin` and `skipOnUnix` to help us manage our platform-dependent
tests. These methods give a nice warning message when we skip tests. We may also
consider adding warnings when running platform-dependent tests.

Part of the motivation for this is if we ever update to AVA v0.19. This version
requires at least one assertion per test case. While this could be disabled with
an AVA setting, we instead benefit from warnings for any case when we
unintentionally skip assertions.

This adds chalk as a dev dependency to enable colored messages.

Subject: [PATCH 145/338] refactor(test): update AVA and refactor tests (#760)

This updates tests for `AVA` 19.0.0+.

`AVA` 0.18.0 has a breaking change which changes the current working directory
for tests. As a result, we need to change 'resources' -> 'test/resources' (and
 similar path changes).

`AVA` 0.19.0 has a breaking change that all tests must run at least one assert.
This breaking change was already resolved by #746, so no change was necessary in
this PR.

This updates to `AVA` 0.21.0, since there are no other breaking changes.

Subject: [PATCH 150/338] chore: set AVA options (#780)

This sets 2 AVA options:

 * `serial`: same behavior as the CLI flag, which this replaces
 * `powerAssert`: if an assert fails, it will inspect all objects involved in
   the failed assert. This causes readability issues if `t.falsy(shell.error())`
   breaks, since it inspects all of `shell` (which is way too large).

AVA options are a little easier to manage than CLI options (we only update one
place instead of 2 in `package.json`).

Adds two new methods to src/common.js, common.statFollowLinks and common.statNoFollowLinks, which wrap fs.statSync and fs.lstatSync, respectively. This change is meant to improve readability and clarify intent.

* Add common.statFollowLinks and common.statNoFollowLinks

* Replace fs.statSync and fs.lstatSync in source files

Subject: [PATCH 155/338] refactor(exec): move child process to source file
 (#786)

This PR refactors `shell.exec()` by putting its child process in a separate code
file. This also slightly cleans up dead code.

There's more potential to clean this up (e.g. exit status), but this is a good
enough start.

Issue #782

Subject: [PATCH 158/338] Use execFileSync to launch child process (#790)

This uses `child_process.execFileSync` instead of `execSync` to launch the child
process. This further reduces the attack surface, removing a possible point for
command injection in the ShellJS implementation.

This does not affect backwards compatibility for the `shell.exec` API (the
behavior is determined by the call to `child_process.exec` within
`src/exec-child.js`).

Subject: [PATCH 159/338] Provide an API to pass parameters which resemble
 options (#792)

This adds the special option string `--`, which means "no options". This can be
passed if the first parameter looks like an option (starts with a `-` followed
by 1+ letters).

Fixes #778

Subject: [PATCH 160/338] chore(eslint): use words instead of numbers (#797)

Eslint rules can be configured either using words or number values:

 * "off" or 0
 * "warn" or 1
 * "error" or 2

This switches our config to use the string values instead of the number
values, since the number values are too cryptic.

No change to our actual settings.

Subject: [PATCH 161/338] Remove codeFile parameter (#791)

This parameter isn't needed, we can easily rely on exit code status for this.

Eliminating the parameter reduces file IO, code complexity, and removes a busy
loop.

This also removes some legacy code related to streams.

The `paramsFile` is obsolete now that we use `execFileSync()` for our
internal implementation. Instead, we pass parameters to the child
process directly as a single commandline parameter to reduce file I/O.

Subject: [PATCH 164/338] refactor: harden plugins against unknown options
 (#804)

This reworks the plugin API such that:

 - Unable to register a command with unknown wrap-options
 - `TypeError` raised for wrap-option type mistakes
 - Remove the `overWrite` option (it's unused, probably safest to not
   expose for now)
 - `cmdOptions` defaults to `null` instead of `false` for type
   consistency (no change to default behavior)
 - Move `pipeMethods` logic into `_register`, since it makes more sense
   there

This is not expected to have any effect on existing plugins.

Subject: [PATCH 169/338] Revert "refactor(exec): remove paramsFile (#807)"
 (#819)

This reverts commit 64d5899abc86dd7b7fa84455c0ce3551786c4b5b.

Reason for revert: If stdin is large, then the param object can become
an extremely long string, exceeding the maximum OS size limit on
commandline parameters.

Original change's description:
> refactor(exec): remove paramsFile (#807)
>
> The `paramsFile` is obsolete now that we use `execFileSync()` for our
> internal implementation. Instead, we pass parameters to the child
> process directly as a single commandline parameter to reduce file I/O.
>
> Issue #782

Fixes #818

Subject: [PATCH 173/338] chore(lint): don't allow excess trailing newlines
 (#816)

* chore(lint): don't allow excess trailing newlines

This enforces that files should not end with blank lines (i.e. more than
one trailing newline). The `eol-last` rule (inherited from airbnb's
config) already enforces that files end in at least one trailing
newline, so adding this rule enforces that it ends in exactly 1.

See https://eslint.org/docs/rules/no-multiple-empty-lines and
https://eslint.org/docs/rules/eol-last for more information.

Inspired by #809.

Subject: [PATCH 174/338] Remove separate "internal error" from exec (#802)

* Remove separate "internal error" from exec

* Fix unknown command error regex

* Add message about command not found regex

* Silence errors while reading files in exec

The stdout and stderr files may never be opened or written to in certain
circumstances. In particular, if the timeout is short enough, the child
node process does not have enough time to start, and the child script
does not execute, so the files are not written to. So, catch errors form
trying to read the files, and ignore them.

* Do not silence errors due to short timeouts

* Simplify test regex for missing command

* Default error code to 1 if not set

Subject: [PATCH 181/338] chore(appveyor): do not use latest npm (#847)

This changes appveyor from using the latest npm version to only using
the preinstalled npm version. This is safer, because it's guaranteed to
be a compatible version.

Fixes #844

Subject: [PATCH 182/338] chore: output npm version in travis (#850)

Knowing the `npm` version was a huge help to debugging issue #844. For
some reason, we output this on appveyor but not on Travis. This PR fixes
that.

Subject: [PATCH 184/338] chore: bump dev dependencies and add package-lock
 (#864)

No change to logic.

This reduces install spam by bumping codecov to avoid depending on a
deprecated graceful-fs version, as well as adding a package-lock.json.

Subject: [PATCH 185/338] fix(mocks): fix conflict between mocks and skip
 (#863)

This fixes a conflict between mocks.init() and
utils.skipOnWin/skipOnUnix. mocks.init() mocks out process.stderr.write,
which utils.js implicitly depends on.

Instead, preserve stderr.write in a local variable to avoid polluting
mocked stdio and to correctly output warning messages.

Fixes #862
Test: locally apply mocks.init() inside test/which.js

This is a redo of PR #555.

This rebases, cleans up a test, and fixes a bug (the original PR uses `fs.chown()` instead of `fs.chownSync()`).

Fixes #98

Subject: [PATCH 188/338] Fix(which): match only executable files (#874)

On Unix, this only matches files with the exec bit set. On Windows, this only
matches files which are readable (since Windows has different rules for
execution).

Fixes #657.

Subject: [PATCH 190/338] docs: remove gitter badge (#880)

No change to logic.

We don't really use the gitter chatroom right now, so we shouldn't
direct users to chat there. It's best to have issues reported directly
on Github.

This PR removes the gitter badge from the README.

No change to logic.

This changes appveyor to run the entire test matrix, even if a failure
occurs early on. This is helpful for debugging.

Subject: [PATCH 192/338] chore(npm): add ci-or-install script (#896)

* chore(npm): add ci-or-install script

This adds a script which checks the npm version and runs either `npm ci`
or `npm install` based on support. This is primarily to work around an
issue where `npm install` modifies `package-lock.json` for newer npm
versions.

A side benefit is that `npm ci` is slightly faster than `npm install`.

Fixes #893

Subject: [PATCH 193/338] fix: silent exec (#892)

Unconditionally apply `silent: true` when calling `common.error()` from
`exec()`. This is because errors are already printed to stderr, or are
intentionally silenced by `shell.config.silent`.

Based on #861

Fixes #851

Subject: [PATCH 195/338] refactor: don't expose tempdir in common.state (#903)

Previously, the cached `tempdir` value was stored in `common.state`.
Unlike the other `common.state` values, this isn't immediately useful to
other commands (they can just call the tempdir API). So, this moves the
cached value into `tempdir.js`.

This also adds a unit test for the caching behavior, and exposes
test-only helpers to verify this behavior.

Finally, this adds a note to `common.state` that values should generally
be considered read-only, since this can be important for customized
behavior. Although, I recognize our code base has one exception to this
rule (`echo()`), we should strive to maintain this.

Fixes #902
Test: Added a unit test.

When we can read all files, but none match, exit 1 and return no output. This
matches the behavior of grep more closely.

No change to logic.

This removes gitter integration with the project. I don't monitor gitter

useful otherwise.

Subject: [PATCH 203/338] chore(npm): remove lockfile (#911)

This removes our lockfile and our `ci-or-install` script. The lockfile
caused headaches, since `npm install` would modify the lockfile.

Unfortunately, `ci-or-install` (added in #896) didn't work reliably on
appveyor, so removing the lockfile seems easier. We remove the script
since it's now obsolete.

Subject: [PATCH 204/338] chore: script to bump supported node versions (#913)

No change to node support, this just adds a script.

This adds a script to check that we correctly configure all supported
node versions, since we need to update quite a few spots (README.md,
package.json, travis, appveyor).

Subject: [PATCH 205/338] chore(node): drop node v4 and v5 (#917)

This drops support for node v4 and v5. Neither is currently supported by
the Node.js team, nor by the `npm` CLI team, so it's hard to justify we
continue to support it.

The new minimum supported version is v6.

Fixes #873

Subject: [PATCH 206/338] fix(exec): consistent error message for maxBuffer
 (#919)

* fix(exec): consistent error message for maxBuffer

This explicitly checks for maxBuffer errors in exec-child.js and
provides a consistent error message. This modifies the test to verify
this.

This also supports the change in Node v10, which emits this as a
RangeError instead of a regular Error.

Although the error message is now explicit, this is not part of our API,
since it's just tacked onto the end of exec's stderr.

Fixes #915

* Remove debugging log, ignore uncovered lines

NYC takes forever on my local machine, and I generally prefer to look at
coverage reports on the website anyway.

This changes `npm test` to run without coverage, and changes our CI to
run `npm run test-with-coverage` instead.

Subject: [PATCH 209/338] test(touch): add coverage for -d option (#925)

No change to production logic.

We never had coverage for `touch({'-d': ...})`, so this adds test
coverage. This also updates documentation to clarify the parameter
should be an instance of the `Date` type.

Test: `handles date argument` case

Subject: [PATCH 210/338] feat(options): initial support for long options
 (#926)

* feat(options): initial support for long options

This adds initial support for long options. This integration tests them
with `shell.touch()` and unit tests them in `test/common.js`. This
documents the new syntax.

This also refactors some of the common internals:

 * Creates a new CommandError type to replace the `'earlyExit'` hack
 * Clearer Error types for `parseOptions()` exceptions
 * Removes side effects from a test which modifies `common.config`
 * Fixes appveyor and travis config to run lint (regressed in #920)

Issue #924
Test: touch.js, common.js

* small refactor for errorOptions

Subject: [PATCH 212/338] docs: clarify which methods return ShellStrings
 (#934)

No change to logic, only docs.

In v0.7.0, we introduced ShellStrings and changed most methods to return
them. Docs weren't appropriately updated, so this PR cross-links these
methods to the ShellString docs.

This also expands on the ShellString docs themselves, since there was
room to make this clearer.

Fixes #933

This upgrades eslint to a new version to resolve a security warning.
This fixes a couple new lint errors, and disables some lint checks.

The current version of the airbnb lint config triggers
DeprecationWarnings in the new version of eslint. These warnings will be
resolved in a follow-up.

Subject: [PATCH 219/338] chore(lint): update lint dependencies (#948)

This updates `eslint-config-airbnb-base` and `eslint-plugin-import`.
This also addresses lint errors these updates raise, and excludes
several rules.

This also adds a minor simplification to the gendocs script.

Subject: [PATCH 220/338] Add boolean `fatal` option to `exec()` function
 (#961)

This PR introduces a new boolean fatal option for the exec() function. Like the existing silent option, this new option allows you to override the global fatal configuration parameter on a per-command basis.

Subject: [PATCH 221/338] test: misc test changes (#970)

No change to production logic.

This renames test cases with duplicate names, deletes a redundant test,
and uses the public `t.title` API in favor of `t._test.title`.

This is a prerequisite for updating ava.

Subject: [PATCH 223/338] Silence potentially upcoming circular dependency
 warning (#973)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Node.js is currently considering printing a warning when a non-existent
property of `module.exports` is accessed while in a circular `require()`
dependency, in order to make it easier to catch issues with circular
dependencies.

In order to avoid printing these warnings for shelljs, checking for the
property’s existence rather than its truthiness suffices.

Subject: [PATCH 224/338] fix(exec): join paths correctly (#975)

Previously, we just concatenated _tempDir() with '/' and a random
filename. Instead, we should join paths with path.join() to use the OS
path separator.

This is a speculative fix for issue #974, although this may not be
enough to actually make Windows happy.

Subject: [PATCH 225/338] feat: add shell.cmd to replace exec (#866)

This adds an initial implementation of shell.cmd(), which is intended as
the eventual replacement for shell.exec(). This PR does not fully
implement the API, but demonstrates a simple and secure alternative, and
will allow further iteration to cover other use cases in follow-up PRs.

Subject: [PATCH 230/338] chore: change supported node versions (#1011)

This adds testing for node v14. This removes testing for node v6 and v7
because codecov breaks on these versions. This omits node v15 because
appveyor doesn't seem to support this version. The nodejs org currently
supports [10, 12, 14, 15].

This makes a couple minor edits to the check-node-support script for
consistency with shelljs/shx#186.

This bumps the shx dependency because it seems we're hitting issue #973
on node v14.

Test: npm run check-node-support

+# ShellJS Security Policy
+
+Thank you for reaching out regarding the security of the ShellJS module! Please
+note that this project is maintained on a best-effort basis, however I still
+intend to prioritize reviewing and addressing security issues.
+
+## Supported Versions
+
+I generally only support the latest ShellJS release (see
+https://www.npmjs.com/package/shelljs). My goal is to release security fixes as
+patch releases on top of whatever was most recently shipped.
+
+If breaking changes have already landed on the main development branch, I may
+apply the patch on the relevant release branch (ex.
+[`0.8-release`](https://github.com/shelljs/shelljs/commits/0.8-release) and
+create a new release from there.
+
+## Reporting a Vulnerability
+
+Please report security vulnerabilities to ntfschr@gmail.com. I should respond
+within a few days. Although it's not strictly required, it helps me out if you
+can include any proof of concept exploit code, suggested fix, etc.
+
+**Please do not publicly disclose the suspected vulnerability** until I have a
+chance to review your report. I'd like a chance to patch the code before the
+issue is known to the public.
+
+Please **only** use this email for security issues. It's also OK to use the
+email if you're legitimately unsure if this is a security issue (better safe
+than sorry). But for all other non-security issues, please use the GitHub issue
+tracker.

Subject: [PATCH 241/338] docs(ls): document the toString() override

No change to logic. This documents `shell.ls('-l')`'s `.toString()`
override. I noticed this feature was not documented. This string format
should not be depended on by programmatic usage, but it's useful to make
things more human readable.

Subject: [PATCH 242/338] docs(chmod): briefly mention Windows file perms

File permissions on Windows are weird. This adds a brief note into the
README that this is something to watch out for. As far as I'm aware, WSL
completely avoids the weirdness because it's actually Linux (and so it
follows POSIX).

Subject: [PATCH 249/338] test(cp): fix cp -Ru test cases

This fixes several issues with the cp -Ru test cases:

* Originally, I noticed the touch syntax looked wrong
* After fixing that, I was trying to figure out how the test case was
  even passing before. I realized one of the assertions was wrong (it
  was asserting sourceFile contents, but should have asserted destFile
  contents)
* I realized the test should have created a nested destination
  directory; without proper nesting, the sourceFile never actually
  collided with destFile during the copy
* Lastly, I swapped touch() usage to use hardcoded timestamps for test
  consistency

Subject: [PATCH 251/338] docs(import): document es6 import command

No change to logic. This documents that we support importing via
`import shell from 'shelljs'`.

Related to issue #1071, although some more investigation is required to
understand why the other syntax doesn't work.

No change to logic. This expands on the `touch()` command documentation
to make it more obvious how to use multiple options, long options, etc.
This also renames a variable in a test case to make the usage more
obvious.

Subject: [PATCH 257/338] fix: shell.errorCode() honors shell.exit(code)

This changes shell.exit() to use a wrapper function. This is so that
shell.errorCode() will have the correct error code after invoking
shell.exit(code). This isn't normally relevant, however a caller may be
listening for the exit status:

```
process.on('exit', code => {
  shell.exit(shell.errorCode());
});
```

Subject: [PATCH 259/338] chore: update nyc to v15

No change to logic. This updates nyc (code coverage tool) to version 15,
which works around a breaking change that snuck into the latest Node LTS
versions.

Unfortunately, this version of nyc appears to break Node 8 and 9. We
need to work around this problem by skipping test coverage on those
versions.

Fixes #1130

Subject: [PATCH 261/338] chore: remove codecov token

It looks like 1a1a820569f0883a317944973c15cf34431dd6c2 actually broke
codecov. Codecov is currently trying to diff all PRs against the commit
before that one, which leads to flagging previously-added lines of code
as needing coverage in the current PR.

Let's try removing the token and see if codecov is happy again.

Fixes #1124

Subject: [PATCH 262/338] test: add coverage for exit function

This adds test coverage for the shell.exit() function. This also
refactors how we mock stdout/stderr and adds support for mocking
process.exit() (which was needed for this change).

While I was writing these tests, I realized there was an edge case I
missed in PR #1122. This change fixes that edge case.

Issue #1013

Subject: [PATCH 267/338] docs: change GitHub Actions README badge

This changes the README to use a standard shields.io badge for GitHub
Actions. The custom badge
(https://github.com/Atrox/github-actions-badge) was cool, but the
atrox.dev link doesn't work reliably. I noticed that shields has support
for this now, so there's no reason to use a custom badge.

One notably difference is that this badge says the build is passing even
if there's a job still in progress.

Subject: [PATCH 268/338] chore: try codecov token again

I tried this recently in 1a1a820569f0883a317944973c15cf34431dd6c2 and
then reverted in b8b1c4224d0ec7d631d26c78922c018dd5b895f5. Unfortunately
I'm still seeing spurious failures from codecov, so let's try the token
one more time.

This time I double checked the token is provided by
https://app.codecov.io/gh/shelljs/shelljs/settings. I regenerated the
token for good measure.

Subject: [PATCH 269/338] test: create test files inside temp directory

No change to logic. This updates some test cases to create the files
they need inside the temp directory instead of in the repo itself. This
is helpful in case the test case fails early, that way we don't leave
this file behind.

This contributes toward #828, since the change to fast-glob made it
clear that this test was mishandling link files and leaving side effects
in the git repo. However this change is desirably independent of
fast-glob.

Subject: [PATCH 272/338] test: add more coverage for globOptions

No change to logic. This adds tests for more `config.globOptions`
values. This aims to cover the options which appear to be supported by

in each module. This is a followup to PR #1163.

Subject: [PATCH 273/338] deprecate config.globOptions

This deprecates support for configuring `config.globOptions`. Exposing
this variable makes it difficult to change (or upgrade) our glob
library. This discourages users from depending on this config option
going forward.

If anyone is using `config.globOptions` then it should continue to
function, however this support is not promised for the long-term.

As far as I know, this is not a commonly used option:
https://github.com/shelljs/shelljs/issues?q=globOptions currently shows
no GitHub issues of users using this option, and there was never really
a motivation for why this needed to be exposed (#400 exposed the option
just because we could, not because we should).

This is one step toward supporting Issue #828.

Subject: [PATCH 278/338] chore: switch to testing LTS releases only

No change to official support. We will still accept patches for non-LTS
versions when it's reasonable to support them, especially for the most
recent Node release (whether that is odd-numbered or even-numbered).
This just lightens up the workload on CI because most of our users are
probably running node LTS.

Dropping support for everything before node v18, which is the current
maintenance LTS and also the version in Ubuntu 24.04 LTS.

This also updates all devDependencies while trying to minimize the
required source code changes. Some devDependencies can go higher still
(ava, chalk), but this is going to require extensive refactoring.

Subject: [PATCH 281/338] refactor: unescape quotes

This swaps out quote characters to limit how often we need to escape
strings. This is just to improve code readability.

Almost all of the changes could be done without changes to .eslintrc,
however this amends the lint rule to also permit backtick strings which
can be useful to eliminate a few extra instances of quote escaping.

Fixes issue #788
Test: npm run lint

Subject: [PATCH 282/338] refactor: switch to fast-glob

This removes `node-glob` in favor of `fast-glob`. The main motivation
for this is because `node-glob` has a security warning and I can't
update to `node-glob@9` unless we drop compatibility for node v8.

Switching to `fast-glob` seems to be fairly straightforward, although
some options need to be changed by default for bash compatibility.

Fixes #828
Fixes #1149

Subject: [PATCH 283/338] feat: expose new shell.cmd()

shell.cmd() was originally implemented in #866, however was not yet
exposed. This command should be ready for people to try out, so this
exposes the command by default.

This is still not a full implementation of everything in the
https://shelljs.page.link/cmd-design design doc, however this completes
the initial phase and is likely good enough to replace most use cases of
synchronous shell.exec().

Fixes #495

Subject: [PATCH 284/338] refactor: move exec-child logic into main function

No change to logic. This refactors the exec-child.js script to move all
of its main logic into a main() function. This function is only invoked
if the script is executed, not when it is imported.

Importing the script is now a NOOP instead of throwing an exception.
It's still not advisable to import the script, however this can be done
if absolutely necessary to trick JavaScript bundlers which try to prune
non-imported code files.

Partially related to issue #1160 and #1172.

Subject: [PATCH 285/338] refactor: rewrite gendocs script without commands.js

The gendocs script no longer depends on commands.js. This now works by
iterating over source files and parsing them directly.

Partially related to issue #1160 and #1172.
Test: npm run gendocs

Subject: [PATCH 287/338] test: document test for newline in cmd() function

No change to logic. This adds documentation for the test case for
handling newlines.

This also removes a nearby eslint suppression which is no longer
necessary after PR #1184.

Fixes #175

Subject: [PATCH 288/338] refactor: prefer includes() over indexOf()

No change to logic. This swaps out Array.prototype.indexOf in favor for
Array.prototype.includes() to simplify logic. This does the same for the
equivalent String.prototype functions.

From 495933f13ae62a342ed18cc942ab14bbbb65e5fd Mon Sep 17 00:00:00 2001

Subject: [PATCH 290/338] chore: update ava dep

No change to logic. This updates ava to major version 2. This is not the
latest version, however updating to version 3 is not trivial because of
some breaking changes.

This removes the commandline options from the ava invocation in favor of
moving this into the well-supported ava JSON configuration. This is
required for Windows compatibility, because otherwise Windows won't
properly expand "test/*.js" on the commandline and ava v2 won't expand
this unless it's specified in the JSON config.

Test: npm test
Test: npm run test-with-coverage

Subject: [PATCH 291/338] Explicitly require commands (#1119)

Currently anything that includes shelljs in it's chain cannot be bundled into a singular file due to the dynamic require. By explicitly requiring everything in src, this allows singular bundles through things like esbuild.

Subject: [PATCH 292/338] refactor: follow up fixes for static imports

No change to logic. This is a follow up to PR #1119. This change:

* Deletes commands.js entirely and edits the 'files' section of
  package.json
* Undoes some duplicate imports (ex. src/error)
* Adds an explicit import for exec-child.js as a hint for the bundler

After this change, I expect that bundlers/minifiers such as esbuild will
now correctly process shelljs.

Fixes #1160

Subject: [PATCH 293/338] docs(changelog): updated by Nate Fischer

Manual changelog update for v0.8.4 and v0.8.5 releases. This also
removes the 'Unreleased' section since it isn't that useful in a
changelog document.

I'm manually updating because it looks like
https://github.com/skywinder/gitlab-changelog-generator is not working
at the moment (this is what shelljs-changelog depends on).

Subject: [PATCH 295/338] fix: add global.js and plugin.js to exports list

We intend for dependent projects to be able to import these files, so
this adds them to the explicit list of supported exports.

Fixes #1195
Test: tested this by running shelljs-plugin-open's test suite.

Subject: [PATCH 297/338] test: add tests for shelljs glob expansion

No change to logic. This adds unit tests for glob expansion.

This includes one test case for behavior which was broken by v0.9.0
(probably due to the switch to fastglob). This behavior hasn't been
fixed yet, so the test is marked as skipped.

Subject: [PATCH 299/338] fix: add package.json to exports list

No change to logic. shx has a dependency on shelljs/package.json so that
it can read the ShellJS version number. This is useful for shx and
probably harmless for other packages (we need to ship the package.json
file anyway), so this adds it to the exports list as an optional export.

Fixes #1195
Test: I ran `shx --version` with this copy of shelljs as the dependency

Subject: [PATCH 303/338] refactor: avoid dependency cycle

Prior to this change, there was a dependency cycle between shell.js and
common.js. This refactors code to avoid the cycle.

This was previously reported in #1133. Node.js already worked around the
issue in v20.6.1, but it's simpler if we can avoid the dependency cycle
on our end anyway.

I tested this with `npm test` and also by running my own script which
uses a shelljs plugin. This seems to work correctly in both cases.

Subject: [PATCH 307/338] refactor: use promises for utils.runScript

No change to logic. This swaps out utils.runScript() to return a Promise
instead of taking a callback. This also moves some of `test.cb()` cases
over to async functions instead.

No change to logic. This is a small refactor to use stricter
"expectation" arguments for calls to t.throws().

Subject: [PATCH 309/338] refactor: prefer promises over test.cb

This is a followup to PR #1211 to use promises everywhere and migrate
away from `test.cb()`. The `test.cb()` function is removed in a future
version of ava.

I made an attempt to convert the skipped shell.cmd() async test cases,
but async functionality isn't implemented so it's possible the test
conversion is not totally correct.

Subject: [PATCH 311/338] refactor: use es6 class syntax for CommandError

This is supposed to be a NOOP, although for some reason this makes a
difference in the ava@6 test framework. This should not have a
user-visible effect because CommandError is an implementation detail of
this library (it's only thrown if `options.fatal` is off, and it's
always caught inside of common.js).

Subject: [PATCH 312/338] chore: update ava

This updates ava to v6. This resolves some `npm audit` warnings in our
project's devDependencies. This adds `workerThreads: false` because
operations like `process.chdir()` don't work in workers (but are
required for shelljs).

This is a partial fix #1180, although I found more errors when I ran the
tests locally on v22.10.0.

Test: npm audit

Subject: [PATCH 313/338] fix: cmd is compatible with node 22.10

Starting in node >= 22.10.0, a commandNotFound error will have
`undefined` values for stdout/stderr, whereas in earlier versions these
values were `null`.

Fixes #1180

Subject: [PATCH 314/338] refactor: explicit handling for execa errors

This adds a dedicated if-condition to handle internal errors from execa
(timeout, maxBuffer, etc.) and to distinguish these from "regular"
errors (the command executed, but it failed with non-zero status).

Subject: [PATCH 316/338] refactor: change how internal errors are handled

This is an internal refactor to change how we handle execa errors inside
of shell.cmd().

This also adds a test case for a command which fails silently to make
sure that we handle this case correctly.

Subject: [PATCH 319/338] chore: remove accidental audit dep

I think this was installed by accident when running `npm audit`. The
`audit` module is entirely unrelated and I didn't meant to add a
dependency on this.

Subject: [PATCH 320/338] Deprecate the shjs binary

This removes the shjs binary. This feature was not widely used and it
was buggy. The recommended workaround is to invoke scripts directly with
'node' (you may also need to set your NODE_PATH environmental variable).

Dropping this script lets us trim down the dependency tree.

For those who still need the original script, the source code has moved
to https://github.com/shelljs/shjs.

Subject: [PATCH 324/338] test: check for README changes in the unit tests

No change to logic. This checks for stale README in the unit tests
instead of by calling 'gendocs' directly.

The main goal is for GitHub CI to stop getting tripped up by
package-lock.json formatting changes. `npm install` sometimes overwrites
the package-lock file with a new format, and this breaks the
after-travis step.

Test: node_modules/.bin/ava test/docs.js

Subject: [PATCH 330/338] fix: expand ? wildcard in non-final path segments
 (#1242)

fast-glob's dependency glob-parent does not recognize the ? wildcard
when it appears in non-final path segments (e.g. test/r?sources/file.txt).
It incorrectly treats "test/r?sources" as a literal directory name, causing
the glob to fail silently and return no matches.

Work around this by converting standalone ? characters to the equivalent
character class [^/] before passing patterns to fast-glob. Both match
exactly one non-slash character, but glob-parent correctly handles [^/].

The conversion preserves ? inside character classes ([?]), escaped
characters (\?), and extglob patterns (?(...)).

Un-skip the existing test for this case and add new test coverage.

Fixes #1197

Subject: [PATCH 337/338] chore: update GitHub Actions

No change to logic. This updates GitHub Actions to their latest
versions. This also ensures we are testing up through Node v26.

The most important part of this is that it updates codecov to v7, which
contains a major bug fix that was blocking all codecov uploads (and
failing all CI test runs).

When Next.js (or any webpack-based bundler) bundles the server-side
code, __dirname is replaced with the bundled output directory (e.g.
.next/server/vendor-chunks/). This causes child_process.execFileSync to
look for exec-child.js in the wrong location, leading to the 'Cannot
find module' error.

Fix: resolve exec-child.js path using require.resolve() at module load
time. require.resolve() always returns the real filesystem path of the
module, unaffected by bundler __dirname transformations.
