 - recvdir - The counterpart to the above that receives the directory sent.
 - brightness.sh - Another small script I've written that controls the brightness of my screen. It works for me, but it may not work for you.

 	 - setclip - Sets the clipboard to the contents of the standard input

 - [colortrans](https://gist.github.com/MicahElliott/719710) - Convert rgb colours to xterm ones
 - nautilus-here - A quick command that  opens nautilus in the current directory. For lazy people :P
 - ssh-retry - I forget where it came from, but this command reepeatedly calls ssh until it succeeds in connecting.

+ - teleport / telepeek - A pair of quick functions in my `.bash_aliases` file for quickly jumping about. Works best if you've got a decent amount of free RAM for the cache.

 ## cloudsurfer.sh
 `cloudsurfer.sh` is a new script I'm writing to bring some of the customisations I store here in this repository to terminals on shared machines - where I can't modify `.bashrc`, for example.
