Check These Out

take a look to command before action
add |sh when you agree the list, I often use that method to prevent typos in dangerous or long operations

python - covert image to base64 string for data URI use
useful if you are using lots of data URI's in your css files

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Screensaver
Console screensaver.

Get your external IP address
Yeah I know it's been up here a million times, but this service is a really clean and nice one. Nothing but your IP address on it. Actually I was to write something like this, and noticed this on appspot... ;)

Print out a man page
man -t manpagename gives a postscript version of said man page. You then pipe it to ls, and assuming you have cups set up, it prints in your default printer.

"What the hell is running on?!" Easily snoop your system's RAM consumption
Works on most unixes, on OpenBSD replace the "-g" parameter at the sort with a "-n".

List only the directories
This command would be useful when it is desirable to list only the directories. 'egrep' chooses only the lines that begin with 'd'.

Make directories for and mount all iso files in a folder

Analyze awk fields
Breaks down and numbers each line and it's fields. This is really useful when you are going to parse something with awk but aren't sure exactly where to start.
