Move all images in a directory into a directory hierarchy based on year, month and day based on exif information
This command would move the file "dir/image.jpg" with a "DateTimeOriginal" of "2005:10:12 16:05:56" to "2005/10/12/image.jpg". This is a literal example from the exiftool man page, very useful for classifying photo's. The possibilities are endless.

remove OSX resource forks ._ files
DESCRIPTION For each dir, dot_clean recursively merges all ._* files with their cor- responding native files according to the rules specified with the given arguments. By default, if there is an attribute on the native file that is also present in the ._ file, the most recent attribute will be used. If no operands are given, a usage message is output. If more than one directory is given, directories are merged in the order in which they are specified.

disable history for current shell session
this will cause any commands that you have executed in the current shell session to not be written in your bash_history file upon logout

ThePirateBay.org torrent search
usage: tpb searchterm example: tpb the matrix trilogy This searches for torrents from thepiratebay and displays the top results in reverse order, so the 1st result is at the bottom instead of the top -- which is better for command line users

Easily decode unix-time (funtion)

Get each users commit amount

Compare two files side-by-side
I found out about this from Unix Power Tools, and thought it was pretty useful. Use the -w option to change the width of the output, and the -s option to suppress lines that are the same in both files.

Get the IP of the host your coming from when logged in remotely
Even faster without the need for cut... :)

All what exists in dir B and not in dir A will be copied from dir B to new or existing dir C
Assumed dir A, B, C are subdirs of the current dir Exact syntax of the command is: rsync -v -r --size-only --compare-dest=/path_to_A/A/ /path_to_B/B/ /path_to_C/C/ (do not omit end-slashes, since that would copy only the names and not the contents of subdirs of dir B to dir C) You can replace --size-only with --checksum for more thorough file differences validation Useful switch: -n, --dry-run perform a trial run with no changes made

Beep siren
Infinitely plays beeps with sinusoidally changing sound frequency. Ideal for alarm on an event.
