Bash Manipulation: Copy and Move Drill

This lesson reinforces a production-safe sequence: copy first, verify, then move or rename to final state. It reduces risk during refactors and incident remediation.

mkdir -p copy-move-demo
printf '%s\n' 'Quarterly report' > copy-move-demo/report.txt
cp copy-move-demo/report.txt copy-move-demo/backup.txt
mv copy-move-demo/backup.txt copy-move-demo/archive.txt

Both commands usually complete silently on success. Confirm with:

ls copy-move-demo

You should see report.txt and archive.txt (with backup.txt removed after move).

Copy-before-move protects source material while you validate downstream steps. This is especially valuable in release prep and log curation pipelines.

• Moving directly without creating a recovery copy.
• Mixing source and destination order.
• Forgetting to inspect resulting filenames.

Try the full loop:

mkdir -p copy-move-demo
printf '%s\n' '# Runbook' > copy-move-demo/runbook.md
cp copy-move-demo/runbook.md copy-move-demo/runbook.bak
mv copy-move-demo/runbook.bak copy-move-demo/runbook-archive.md
ls copy-move-demo

Repeat until source/destination ordering becomes instant and error-free.
