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.

Check These Out

Find the package that installed a command

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Determine command type (alias, keyword, function, builtin, or file)

Prints a string indicating whether a command is an alias, keyword, function, builtin, or file. I have used this in my BASH scripts to allow an external parameter to define which function to run, and ensure that it is a valid function that can indeed be run.

Convert file type to unix utf-8

converts encoding of a file to unix utf-8 useful for data files that contain what would be usable ascii text but are encoded as mpeg or some other encoding that prevents you from doing common manipulations like 'sed'

See system users

Convert text to lowercase

Usage: lower [STRING]...

Attach screen over ssh

Directly attach a remote screen session (saves a useless parent bash process)

list all executables in your path

If run in bash, this will display all executables that are in your current $PATH

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

Merge various PDF files
