Print a monthly calendar with today's date highlighted
The cal command is handy, but sometimes you want to quickly see today's date highlighted. That's why I came up with this quick command. Much like http://www.commandlinefu.com/commands/view/1342/show-this-months-calendar-with-todays-date-highlighted but cleaner and more succinct.

Remove all .svn folders

find builtin in bash v4+
This command will give you the same list of files as "find /etc/ -name '*killall' | xargs ls -l". In a simpler format just do 'ls /etc/**/file'. It uses shell globbing, so it will also work with other commands, like "cp /etc/**/sshd sshd_backup".

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

Pulse Volume Control Using Zenity
This produces a little bar that you can use to set the volume percentage.

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

Mount a truecrypt drive from a file from the command line interactively
It seems to completely void the benefit of having an encrypted folder if you then have a script on your unencrypted hard drive with your password in it. This command will mount a truecrypt file at a given mount point after asking you for the password.

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

Zip a directory on Mac OS X and ignore .DS_Store (metadata) directory
If you want to generate a cross-platform compatible zip file and ignore the Finder's hidden metadata directory

Generate a random password 30 characters long
Find random strings within /dev/urandom. Using grep filter to just Alphanumeric characters, and then print the first 30 and remove all the line feeds.
