There are some pretty good live performances on late night TV. With Mythtv I record David Letterman, Jimmy Fallon, and Conan nightly all in HD from over the air broadcasts. If I find a live performance I like I copy it to my Rockboxed iPod using this command. The Rockbox firmware knows how to downmix 5.1 audio. The command above extracts the audio from the video starting at 58 minutes and 15 seconds. It ends at the end of the file since this was the last performance of the recording. The command creates an ac3 file. I copy the ac3 file to my Rockbox iPod and rock on.
Converts any number of seconds into days, hours, minutes and seconds.

Update - now fixed.
Probably the quickest / easiest way to clear the screen.
When you don't have c_rehash handy. Really simple - if you have a .pem file that doesn't really contain a x509 cert (let's say, newreq.pem), it will create a link, simply called '.0', pointing to that file.
Useful if you want get all the md5sum of files but you want exclude some directories. If your list of files is short you can make in one command as follow:
$ find . -type d \( -name DIR1 -o -name DIR2 \) -prune -o -type f -exec md5sum {} \;
Alternatively you can specify a different command to be executed on the resulting files.
This is a very simple and lightweight way to play DI.FM stations
For a more complete version of the command with proper strings in the menu, try: (couldnt fit in the command field above)
$zenity --list --width 500 --height 500 --title 'DI.FM' --text 'Pick a Radio' --column 'radio' --column 'url' --print-column 2 $(curl -s http://www.di.fm/ | awk -F '"' '/href="http:.*\.pls.*96k/ {print $2}' | sort | awk -F '/|\.' '{print $(NF-1) " " $0}') | xargs mplayer
This command line parses the html returned from http://di.fm and display all radio stations in a nice graphical menu. After the radio is chosen, the url is passed to mplayer so the music can start
dependencies:
- x11 with gtk environment
- zenity: simple app for displaying gtk menus (sudo apt-get install zenity on ubuntu)
- mplayer: simple audio player (sudo apt-get install mplayer on ubuntu)
