Check These Out

ssh X tunneling over multiple ssh hosts (through ssh proxy)
Simply makes it possible to launch any X application residing on sshhost through sshproxy and display it on your screen where ever you are.

Recursively search and replace old with new string, inside every instance of filename.ext
This is a slightly modified version of http://www.commandlinefu.com/commands/view/4283/recursive-search-and-replace-old-with-new-string-inside-files (which did not work due to incorrect syntax) with the added option to sed inside only files named filename.ext

Stream and copy a video from lan
Requires a listening port on HOST eg. "cat movie.mp4 | nc -l 1356 " (cat movie.mp4 | nc -l PORT) Useful if you're impatient and want to watch a movie immediately and download it at the same time without using extra bandwidth. You can't seek (it'll crash and kill the stream) but you can pause it.

Deploy git server repo
After, check if working by executing this command locally : git clone git@192.168.0.18:repositories/gitosis-admin.git Tutorial : http://blog.hemca.com/?p=560
