Insert a comment on command line for reminder
Comments can be used directly on the command line so I can save in the history a brief description of what command does.

Extended man command
This microscript looks up a man page for each word possible, and if the correct page is not found, uses w3m and Google's "I'm feeling lucky" to output a first possible result. This script was made as a result of an idea on a popular Linux forum, where users often send other people to RTFM by saying something like "man backup" or "man ubuntu one". To make this script replace the usual man command, save it as ".man.sh" in your home folder and add the following string to the end of your .bashrc file: alias man='~/.man.sh'

Convert ascii string to hex
If you're going to use od, here's how to suppress the labels at the beginning. Also, it doesn't output the \x, hence the sed command at the end. Remove it for space separated hex values instead

Trace and view network traffic
Trace and view network traffic. I made this far too complicated.. now fixed, thanks zolden.

check the status of 'dd' in progress (OS X)
While a dd is running in one terminal, open another and enter the while loop. The sample output will be displayed in the window running the dd and the while loop will exit when the dd is complete. It's possible that a "sudo" will need to be inserted before "pkill", depending on your setup, for example: $ while pgrep ^dd; do sudo pkill -INFO dd; sleep 10; done

Run the Firefox Profile Manager
even when another instance is already open. Great for testing purposes when you need to be 2 people at once on the same site.

Re-use the previous command output
The $(!!) will expand to the previous command output (by re-running the command), which becomes the parameter of the new command newcommand.

Ultimate current directory usage command
Based on the MrMerry one, just add some visuals and sort directory and files
