This command clones an image three times and creates a 'tile' image that can be used for a repeating pattern wallpaper. Add 'rm $f $of $off' to the end for cleanup (command was too long to submit with it). See this link for an example: http://meathive.deviantart.com/art/Easy-Photography-Hack-314846774

This command, or a derivative like it, is a must-have if you're a server administrator interested in website optimization: https://kinqpinz.info/?%C2%B6=287a7ba6 Command requires Yahoo's YUI, find it here: http://developer.yahoo.com/yui/ Show Sample Output

My variation on an audio burning command from commandlinefu - this one doesn't crap out if you want to burn a CD in a directory whose permissions don't allow it, and instead rips everything to /tmp. If you mount your music partition like I do using Samba, you probably don't have write permission inside that file system in order to create the temporary directory other audio burning commands here use. Not a bad idea to add cdrom to your groups, and /bin/eject with visudo.

This command will format your alias or function to a single line, trimming duplicate white space and newlines and inserting delimiter semi-colons, so it continues to work on a single line. Show Sample Output

This command will automate the creation of ESSIDs and batch processing in pyrit. Give it a list of WPA/WPA2 access points you're targeting and it'll import those ESSIDs and pre-compute the potential password hashes for you, assuming you've got a list of passwords already imported using: pyrit -i dictionary import_passwords Once the command finishes, point pyrit to your packet capture containing a handshake with the attack_db module. Game over. Show Sample Output

A shortcut to generate documentation with phpdoc. Defaults to HTML; optionally to PDF if third argument is given. Stores documentation in cwd under ./docs/. I forget the syntax to the output, -o, option, so this is easier.

newly downloaded videos goyoutube random goyoutube rand This command assumes you've already downloaded some YouTube .mp4 or .flv video files via other means. Requires 'shuf', or your own stdin shuffler.

gorecord foo.mp4 I've tried all of the screen recorders available for Linux and this is easily the best. xvidcap segfaults; VNC is too much hassle. There are alternatives of this command already here that I am just too lazy to reply to. Messing with the frames per second option, -r, 25 seems to be the best. Any lower and the video will look like a flipbook, if it records at all - -r 10 won't - any faster is the same, oddly enough. Edit: CLF doesn't like my long command to add audio, so here it is in the description. goaddaudio() { if [ $# != 3 ]; then echo 'goaddaudio < audio > < src video > < dst video >' return fi f=goaddaudio$RANDOM ffmpeg -i "$2" &> $f d=$( grep Duration $f | awk '{print $2}' | tr -d ',' ) && rm $f && ffmpeg -i "$1" -i "$2" -r 25 -ab 192k -ar 44100 -sameq -t $d "$3" }

If Firefox is your daily browser, be a good Orwellian and run this command regularly. If you see, 'SQL error near line 1: database is locked', close Firefox and run again.
