What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Share Your Commands

Check These Out

repeat a command every one second

Short method of "while x=0; do foo ; sleep 1 ; done"

Mark packages installed with build-dep for autoremove (on Debian/Ubuntu)

Replace PACKAGE with desired package name. Found here: http://mikebeach.org/2011/04/undo-apt-get-build-dep/

Find the package that installed a command

Find out when your billion-second anniversary is (was). (on OS X)

This is the same command as this one, but for OS X. http://www.commandlinefu.com/commands/view/3053/find-out-when-your-billion-second-anniversary-is-was.

Intercept, monitor and manipulate a TCP connection.

Forwards localhost:1234 to machine:port, running all data through your chain of piped commands. The above command logs inbound and outbound traffic to two files. Tip: replace tee with sed to manipulate the data in real time (use "sed -e 's/400 Bad Request/200 OK/'" to tweak a web server's responses ;-) Limitless possibilities.

Rename files in batch

Use a var with more text only if it exists

See "Parameter Expansion" in the bash manpage. They refer to this as "Use Alternate Value", but we're including the var in the at alternative.

Pause Current Thread

Hold ctrl and press z to pause the current thread. Run $fg to resume it.

Find the package that installed a command

spawn shell listener service with nc
