Output system statistics every 5 seconds with timestamp
See man vmstat for information about the statistics. This does the same thing without the timestamp: $vmstat 5

Print the detailed statistics of transferred bytes by the firewall rules

Play online music videos in terminal
pvl 'link1' 'link2' 'link3' Play Youtube, Vimeo, etc links without visual elements. Great for music videos when you just want the audio. You can control mplayer with this! Hit Ctrl-C twice to exit (if you're playing multiple files)

Extract audio from start to end position from a video
mplayer -vc null -vo null -ao pcm Firefly\ ep\ 10.avi -ss 195 -endpos 246 Will create file audiodump.wav with audio from second 195 to second 246 (the opnening theme).

get a mysqldump with a timestamp in the filename and gzip it all in one go
Performs a mysqldump and gzip-compresses the output file with a timestamp in the resulting dump file. Inspect the file for integrity or fun with this command afterward, if you desire: $ zcat mysqldump-2009-06-12-07.41.01.tgz | less

Keep a copy of the raw Youtube FLV,MP4,etc stored in /tmp/
Certain Flash video players (e.g. Youtube) write their video streams to disk in /tmp/ , but the files are unlinked. i.e. the player creates the file and then immediately deletes the filename (unlinking files in this way makes it hard to find them, and/or ensures their cleanup if the browser or plugin should crash etc.) But as long as the flash plugin's process runs, a file descriptor remains in its /proc/ hierarchy, from which we (and the player) still have access to the file. The method above worked nicely for me when I had 50 tabs open with Youtube videos and didn't want to have to re-download them all with some tool.

SVN Command line branch merge
This will merge all of the changes from {rev_num} to head on the branch to the current working directory

diff the same file in two directories.
This is useful when you're diffing two files of the same name in radically different directory trees. For example: Set $ path1='/some/long/convoluted/path/to/all/of/your/source/from/a/long/dead/machine' then $ path2='/local/version/of/same/file' then run the command. Much easier on the eyes when you're looking back across your command history, especially if you're doing the same diff over and over again.

Remove annoying OS X DS_Store folders
Recursively removes all those hidden .DS_Store folders starting in current working directory.

Hypnosis
for OS X
