Check These Out
Displays six rows and five columns of random numbers between 0 and 1. If you need only one column, you can dispense with the "for" loop.
This is what I came up to generate XKCD #936 style four-word password.
Since first letter of every word is capitalized it looks a bit more readable to my eyes.
Also strips single quotes.
And yes - regex is a bit of a kludge, but that's the bes i could think of.
This command prints the Date (Not time) from 3 days ago (72 hours ago).
This works on systems without GNU date (MacOSX , Solaris, FreeBSD).
Google just released a new commend line tool offering all sorts of new services from the commend line. One of them is uploading a youtube video but there are plenty more google services to interact with.

Shorter and more straightforward.
Also in perl:
$ perl -e 'print join(":", map { sprintf "%0.2X",rand(256) }(1..6))."\n"'
In OSX you would have to make sure that you "sudo -s" your way to happiness since it will give a few "Permission denied" errors before finally spitting out the results. In OSX the directory structure has to start with the "Users" Directory then it will recursively perform the operation.

There's been so many ways submitted to get your external IP address that I decided we all need a command that will just go pick a random one from the list and run it. This gets a list of "Get your external IP" commands from commanlinefu.com and selects a random one to run. It will run the command and print out which command it used.
This is not a serious entry, but it was a learning exercise for me writing it. My personal favourite is "curl icanhazip.com". I really don't think we need any other ways to do this, but if more come you can make use of them with this command ;o).
Here's a more useful command that always gets the top voted "External IP" command, but it's not so much fun:
$ eval $(curl -s http://www.commandlinefu.com/commands/matching/external/ZXh0ZXJuYWw=/sort-by-votes/plaintext|sed -n '/^# Get your external IP address$/{n;p;q}')
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.
