MP3 player
I tried a few curses based mp3 players for playing back choir practice songs for my wife. Unfortunately none of the ones I tried were capable of scrubbing a track. Firefox saves the day.

Watch the progress of 'dd'
Pressing ctrl-t will display the progress

print code 3-up and syntax-highlighted for easy beach-time study
This is the setup I'm using for my largest project. It gives 357 lines per page (per side), which makes it fairly easy to carry around a significant amount of code on a few sheets of paper. Try it. (I stick to the 80 column convention in my coding. For wider code, you'll have to adjust this.)

Search some text from all files inside a directory

escape any command aliases
e.g. if rm is aliased for 'rm -i', you can escape the alias by prepending a backslash: rm [file] # WILL prompt for confirmation per the alias \rm [file] # will NOT prompt for confirmation per the default behavior of the command

Encode file path to URL
Really helpfull when play with files having spaces an other bad name. Easy to store and access names and path in just a field while saving it in a file. This format (URL) is directly supported by nautilus and firefox (and other browsers)

Get last sleep time on a Mac

Output files without comments or empty lines
better integration. works on all Unices works one bash and ksh.

Get the time since epoch. Useful when working with commands and logs which use this format.
