Pro Tips
Use 'grep -r' for recursive search, 'grep -i' for case-insensitive, combine as needed.
Use 'sort | uniq -c | sort -rn' to count and rank occurrences of lines.
For JSON processing, use 'jq' instead of sed/awk - it understands JSON structure.
Common Mistakes
sed -i modifies files in place. Use 'sed -i.bak' to create backups before editing.
