Start a quick rsync daemon for fast copying on internal secure network
"Sample output" shows a minimalistic configuration file.

move cursor to beginning of command line
Pressing Ctrl combined with 'a' will move the cursor to the beginning of the command under bash (other shells?). I used to do this after arrowing up for the last command, then typing 'sudo ' to run the last command as root, but of course the all time greatest command here `sudo !!` is more succinct. Still Ctrl+A can be very useful when you want to edit something at/close to the beginning of the command line.

Compare a remote dir with a local dir
You can compare directories on two different remote hosts as well: $ diff -y

Count lines of source code excluding blank lines and comments
Much more accurate than other methods mentioned here straight out of the box.

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.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

swap stdout and stderr
Possible use, to filter something in stderr: (/usr/bin/$COMMAND $PARAM 3>&1 1>&2 2>&3 | grep -v $uninteresting_error ) 3>&1 1>&2 2>&3

List all global top level modles, then remove ALL npm packages with xargs
