What's Your Most Underrated Developer Tool? I'll Start.

Mine is jq . I use it every single day, and I'm constantly surprised how many developers don't know it exists. # Pretty-print any JSON curl -s https://api.github.com/users/torvalds | jq . # Extract specific fields cat data.json | jq '.users[] | {name, email}' # Filter and transform cat logs.json | jq '[.[] | select(.status >= 400)] | length' Before jq , I was writing Python scripts to parse JSON. Now it's a one-liner. My Other "Nobody Talks About This" Tools httpie — Better curl # Instead of: curl -X POST https://api.example.com/data -H "Content-Type: application/json" -d '{"key":"value"}' # Just: http POST api.example.com/data key = value bat — Better cat Syntax highlighting, line numbers, git integration. Just replace cat with bat and everything looks better. fd — Better find # Instead of: find . -name "*.py" -type f # Just: fd -e py ripgrep (rg) — Better grep # 10x faster than grep, respects .gitignore by default rg "TODO" --type py fzf — Fuzzy finder for everything # Search command
