Sneaky CLI Tricks You Probably Missed

Here's a fast burst of command-line goodness to shake up your dev life.

1. Instantly Dig Up Old Commands With `history`, `grep`, and `fzf`

Ever find yourself blanking on that Docker command you used last week? Same. Just run:

history | grep docker | fzf

Scroll, pick the one you need, hit Enter, and boom—it's back at your prompt. Feels like magic, but nope, that's just fzf working for you.

2. Track Down When Code Snippets Showed Up in Git

Stop scrolling forever trying to figure out when someone slipped in that random line of code. You can search your git history by file contents with the -S flag:

git log -S "resizeObserver" --oneline -- src/components/header.tsx

Now you know exactly when that string landed. No more endless digging.

3. Pretty-Print JSON—No Extra Installs Needed

Sick of reaching for jq every time you want to read some messy JSON? Turns out python3 can handle it out of the box:

cat response.json | python3 -m json.tool | less

No extra installs, no hassle.

4. Dead-Simple Port Forwarding With SSH

Want to show off your local site on port 3000? Don't bother with ngrok and logins. Just run:

ssh -R 80:localhost:3000 ssh.localhost.run

You'll get a public URL right away. Drop it in Slack, then sit back and watch the surprised reactions roll in.

5. Time Anything—No Stopwatch, No Fuss

Ever wonder why your linter takes so long? Find out for real:

time (npm run lint > /dev/null)

Tip: stick this in a pre-push hook so you can stop slow commands before they wreck your workflow.
