Replicate a directory structure dropping the files

climagic's New Year's Countdown clock
This is the 140 character long new year's countdown timer that was posted to the climagic account on twitter and identi.ca. There are saner ways of doing this of course, but probably none of those would fit. Uses the figlet command, but of course you can replace figlet with just echo if you want.

Search previous commands from your .bash_history
This is not actually a command, it's just a keyboard shortchut. But a very useful one.

Create multiple subfolders in one command.

dd with progress bar
piping through 'pv' shows a simple progress/speed bar for dd. This is a replacement for my otherwise favorite 'while :;do killall -USR1 dd;sleep 1;done'

Check your unread Gmail from the command line
notice what happens when there is more than one unread message in a thread... also people please dont hardcode the password when you use curl. Leave it out and curl will ask you when it runs. Please...?

Rename file to same name plus datestamp of last modification.
FILENAME=nohup.out mv -iv $FILENAME{,.$(stat -c %Y $FILENAME)} does it help ?

Generate 2000 images with its number written on it

split a string (2)

Runs previous command replacing foo by bar every time that foo appears
Very useful for rerunning a long command changing some arguments globally. As opposed to ^foo^bar, which only replaces the first occurrence of foo, this one changes every occurrence.
