Temporarily ignore known SSH hosts
you may create an alias also, which I did ;-) alias sshu="ssh -o UserKnownHostsFile=/dev/null "

Outgoing IP of server
Faster than the curl/wget-approaches.

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}

Lists all files and directories with modified time newer than a given date
This is great for looking for files that have been updated recently. Logs especially or monitoring what files were added during an install.

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.

Show sorted list of files with sizes more than 1MB in the current dir

draw honeycomb
Fill the entire terminal screen. Is COLUMNS or LINES are undefined run "resize"

nmap IP block and autogenerate comprehensive Nagios service checks

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

Create an easy to pronounce shortened URL from CLI
Shorter regex.
