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

Calculate sum of N numbers (Thanks to flatcap)

replaces "\n" with "+"

Show a prettified list of nearby wireless APs

Check if a string is into a variable

Returns true (0) if the string is into $var, or false (1) if not.

calculate the total size of files in specified directory (in Megabytes)

the command will calculate the size of hidden files

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"

Re-emerge all ebuilds with missing files (Gentoo Linux)

This loops through all installed ebuilds and checks if every file that should be installed is still there and if not adds it to emerge. It includes a verbose output to stderr too. If you have packages installed that have whitespace in their filenames you have to change the IFS to "newline".

Don't save commands in bash history (only for current session)

Only from a remote machine: Only access to the server will be logged, but not the command. The same way, you can run any command without loggin it to history. ssh user@localhost will be registered in the history as well, and it's not usable.

Find if $b is in $a in bash

How many days until the end of the year

What is my public IP-address?

Very effective, use only DNS protocol. The @ part is optional if you already set opendns servers as default ns servers.

Stay in the loop…
