Get your external IP address with a random commandlinefu.com command
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}')

BASH: Print shell variable into AWK

Change gnome-shell wallpaper

Check every URL redirect (HTTP status codes 301/302) with curl

resize all JPG images in folder and create new images (w/o overwriting)
Convert all jpegs in the current directory into ~1024*768 pixels and ~ 150 KBytes jpegs

generate iso

Summarize size of all files of given type in all subdirectories (in bytes)
This deals nicely with filenames containing special characters and can deal with more files than can fit on a commandline. It also avoids spawning du.

ps grep with header
Yet another ps grep function, but this one includes the column headings.

list block devices
Shows all block devices in a tree with descruptions of what they are.

Unzip multiple files with one command
With this command you can easily unzip multiple zip files with just one command. All you need to do is to use single quotes.
