Terminal Tuesday: `sed 's/old/new/' file` previews a text substitution without changing the original. Add `g` for every match on a line. Preview first; `-i` edits the file in place.

Terminal Tuesday: `less filename` reads long text one screen at a time. Try `less /var/log/syslog`; use `/` to search and `q` to quit. Tip: it’s a viewer, not an editor, so you can inspect files safely.

Terminal Tuesday: `sort -n scores.txt` displays lines in numeric order. Use `-n` because sort treats values as text by default. Save a separate result with `sort -n scores.txt > sorted-scores.txt`.

Terminal Tuesday: `wc -l path/to/file` counts lines in a file.

Example: `wc -l ~/Documents/meeting-notes.txt`

Tip: quote paths with spaces. Line count ≠ paragraph count.

Terminal Tuesday: use `du -sh ~/Downloads` to see how much space your Downloads folder uses. Add `--max-depth=1` to see immediate subdirectories. `du` only reports usage, so check paths before cleaning up.
