10 CLI Tools Every Developer Should Automate in 2026

Manual work is the enemy of productivity. Here are 10 CLI tasks you should automate today — with working code examples.

pip install ai-agent-toolkit
web-fetch https://api.github.com/repos/torvalds/linux | json-query .stargazers_count

2. JSON Query Tool

No more cat file.json | python -m json.tool | grep madness.

json-query '.users[] | select(.age > 18) | .name' data.json

Automatically run tests or rebuild when files change:

file-watch --dir ./src --pattern "*.py" --cmd "pytest -x"

Extract errors, warnings, and patterns from messy log files:

log-parse --level ERROR --since 1h /var/log/app.log

Monitor endpoints and get alerted on downtime:
