To play a file at 1.5 times normal speed without increasing the pitch

Find out what the day ends in

Several people have submitted commands to do this, but I think this is the simplest solution. It also happens to be the most portable one: It should work with any sh or csh derived shell under any UNIX-like OS. Oh by the way, with my German locale ($LC_TIME set appropriately) it prints "g" most of the time, and sometimes (on Wednesdays) it prints "h". It never prints "y".

Create and replay macros in vim

You can record, then replay a series of keystrokes in vim. In command mode 'q', then a letter [a-zA-Z] starts macro recording mode. Enter a series of vim commands. When done, enter command mode again, and press 'q' to stop recording. To replay, enter command mode, then press @{letter}

Create commands to download all of your Google docs

Create commands to download all of your Google docs to the current directory.

Generate diff of first 500 lines of two files

Useful for massive files where doing a full diff would take too long. This just runs diff on the first 500 lines of each. The use of subshells to feed STDIN is quite a useful construct.

Find all dot files and directories

Show CPU usage for EACH cores

Dump the root directory to an external hard drive

This will compress the root directory to an external hard drive and split it to parts once it reaches the 4 Gigs file system limit. You can simply restore it with: $ restore ivf /media/My\ Passport/Fedora10bckup/root_dump_fedora
