In this project, I practiced using core shell commands to process and analyze text files efficiently. Key skills learned:

List and explore files using ls
Search for patterns and count occurrences with grep
Sort data numerically, alphabetically, and by columns using sort
Identify duplicates and count them with uniq
View the beginning or end of files using head and tail
Combine commands with pipelines to perform multi-step data processing in one line

… first attempt

…nd their last attempt

…utput it

… last result

…n the word Dcotor

…n the word Dcotor with ignoring

…regardiling the senesitive case

…the line before

…contain any other upper case letter

 # TODO: Write a command to output just the names of each player along with the number of times they've played the game.
 # Your output should contain 6 lines, each with one word and one number on it.
 # The first line should be "Ahmed 3".


Works but hardcoded and not flexible.

yassineyahya-occ · 2026-04-09T08:11:24Z


+grep "" dialogue.txt
 # TODO: Write a command to output every line in dialogue.txt said by the Doctor.
 # The output should contain 6 lines.


Matches all lines, no filtering.

yassineyahya-occ · 2026-04-09T08:11:42Z


+grep -F "Doctor" dialogue.txt
 # TODO: Write a command to output every line in dialogue.txt that contains the word Doctor (regardless of case).
 # The output should contain 9 lines.


Missing case-insensitive flag (-i).

yassineyahya-occ · 2026-04-09T08:12:07Z

 # TODO: Write a command to output input.txt with all occurrences of the letter `i` replaced with `I`.
 # The output should contain 11 lines.
 # The first line of the output should be: "ThIs Is a sample fIle for experImentIng wIth sed.".
+sed 's/i/I' input.txt


Missing g , only replaces first match per line.

 # The input for this script is the person.json file.
 # TODO: Write a command to output the name of the person.
+jq '.name' person.json
 # Your output should be exactly the string "Selma", but should not contain any quote characters.


Missing -r, output includes quotes.

yassineyahya-occ · 2026-04-09T08:12:46Z


 # The input for this script is the person.json file.
 # TODO: Write a command to output the address of the person, all on one line, with a comma between each line.
+jq -c '.address | join(", ")' person.json


Missing -r, output includes quotes.

yassineyahya-occ · 2026-04-09T08:12:52Z

 # The input for this script is the person.json file.
 # TODO: Write a command to output the name of the person, then a comma, then their profession.
+jq  '[.name, .profession] | join(", ")' person.json
 # Your output should be exactly the string "Selma, Software Engineer", but should not contain any quote characters.


Missing -r, output includes quotes.

yassineyahya-occ · 2026-04-09T08:12:59Z

 # TODO: Write a command to output just the names of each player, one per line.
+jq '.[].name' scores.json
 # Your output should contain 6 lines, each with just one word on it.
 # Your output should not contain any quote characters.


Missing -r, output includes quotes.

 Convert the decimal number 14 to binary.
 Answer:
-
+0001 0100


Incorrect conversion (should be 1110)

 If reading the bytes 0xAA00FF as an RGB colour, as described in "Approaches for Representing Colors and Images", what colour would it mean?

Missing answer

 # The input for this script is the events.txt file.
 # TODO: Write a command to show how many times anyone has entered and exited.
 # It should be clear from your script's output that there have been 5 Entry events and 4 Exit events.
+sort events.txt | uniq --group


Doesn’t count occurrences (wrong tool/flags)

yassineyahya-occ · 2026-04-09T08:15:47Z

 # TODO: Write a command to show how many times anyone has entered and exited.
 # It should be clear from your script's output that there have been 5 Entry events and 4 Exit events.
 # The word "Event" should not appear in your script's output.
+sort events.txt | uniq --group


Same issue as above

yassineyahya-occ · 2026-04-09T08:16:10Z

 # so every Y should be a Z, and every Z should be a Y!
 #
 # TODO: Write a command to output the contents of text.txt with every Y and Z swapped (both upper and lower case).
+cat text.txt | tr 'Z' 'z' | tr 'Y' 'y' | tr 'z' 'Z' | tr 'y' 'Y'


Incorrect swap logic; transforms incorrectly

Good overall work, but watch for missing flags and choose the correct tools/filters more carefully.
good job Hamdi !
