Check These Out

Use GNU info with a pager
This makes GNU info output menu items recursively and pipe its contents to less, allowing one to use GNU info in a manner similar to 'man'.

Speed up launch of firefox
Compress information DBs of firefox to speed up the launch of browser.

Makes you look busy
This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim. Drop this in your .bash_aliases and make sure that file is initialized in your .bashrc.

Length of longest line of code
Here's an awk version.

move messages directly from one IMAP inbox to another
This one-liner was useful in helping someone I know to get off of MS Exchange. `mailutil` proved to be a much better alternative than `fetchmail` or `getmail` in this case. It quickly moved all mails to the destination server (a simple Dovecot/Maildir setup), with no need to convert back and forth between mbox/maildir on the user's own system.

Delete all empty lines from a file with vim

Colored SVN diff
Simple way to achieve a colored SVN diff

command line Google I'm Feeling Lucky
opens the Google I'm Feeling Lucky result in lynx, the command line browser
