Welcome to r/linuxtricks — The home for Linux one-liners, shell tricks, and CLI hacks

If you've ever typed a command and thought "there has to be a shorter way"

— you're in the right place.

r/linuxtricks is a community for practical Linux tricks, shell one-liners,

and CLI shortcuts that actually save time. No fluff, no theory — just

commands that work.

**What belongs here:**

- Shell tricks (bash, zsh, fish, ksh, posix)

- CLI tool shortcuts (awk, sed, tmux, vim, openssl, kubectl and more)

- Sysadmin one-liners that make you look like a wizard

- Anything that saves keystrokes and runs on Linux

**The rules are simple:**

1. Test your command before posting — working code only

2. Label your shell or tool in the title e.g. [bash] or [openssl]

3. Free tools mentioned in context are fine — sales pitches are not

4. Be kind to beginners — everyone started somewhere

**How to post:**

Share a trick with a working example and a one-line explanation of what

it does. The best posts show the before and after — what most people do

vs the shortcut.

**To kick things off** — here's the trick that started this community:

Stop typing the filename twice. Brace expansion handles it.

Instead of:

cp config.yml config.yml.bak

Just write:

cp config.yml{,.bak}

Works in bash and zsh. Been saving keystrokes for 28 years.
