✅ Self-Checklist (applied to Bash commands)
I understood how each command works on files and streams.
I tested my pipelines locally before combining commands.
I used quoting correctly (single ' vs double " for patterns).
I applied filters and transformations with grep, cut, tr.
I verified numeric sorting and counting with sort -n, uniq -c.
I combined commands in pipelines (|) safely.
I formatted output clearly for human-readable results.
