- 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.
- ptr - A small script I wrote that uses `dig` to do PTR (reverse DNS) lookups, since I have to keep looking the command up every time :P
- *clip
- * clip
- setclip - Sets the clipboard to the contents of the standard input
- getclip - Sends the current clipboard contents out of the standard output
- listenclip - Listens on localhost:5556 and pipes any data recieved into the clipboard. Make sure you're firewall is working correctly!

- [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.
- quote-get - Displays a random quote from a remote file. The quote stays the same until the following day. The remote file is cached locally for convenience :smiley_cat:
- 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.
