Stream YouTube URL directly to MPlayer
A function for streaming youtube to mplayer. The option "-g" for youtube-dl tells it to output the direct video URL, instead of downloading the video. "-fs" tells MPlayer to go FullScreen, and "-quit" makes it less verbose. Requires: youdube-dl ( http://bitbucket.org/rg3/youtube-dl/ ) (Tested in zsh)

Countdown Clock
Simple countdown clock that should be quite portable across any Bourne-compatible shell. I used to teach for a living, and I would run this code when it was time for a break. Usually, I would set "MIN" to 15 for a 15-minute break. The computer would be connected to a projector, so this would be projected on screen, front and center, for all to see.

Set CDPATH to ease navigation
CDPATH tells the cd command to look in this colon-separated list of directories for your destination. My preferred order are 1) the current directory, specified by the empty string between the = and the first colon, 2) the parent directory (so that I can cd lib instead of cd ../lib), 3) my home directory, and 4) my ~/projects directory.

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

Running scripts after a reboot for non-root users .
Sometimes we may want to run a script when a system reboots . We can simply do this by just scheduling the script using vixie cron with the @reboot option . e.g @reboot I use it to send me an alert message on our prod hosts to send an alert message when the system reboots . @reboot zaman uptime | echo `uptime` | mail -s "`uname -n` got rebooted" me@myhost.com
