Calculate N!

Display the top ten running processes - sorted by memory usage
ps returns all running processes which are then sorted by the 4th field in numerical order and the top 10 are sent to STDOUT.

ssh autocomplete
Add to your bash profile to minimize carpal tunnel syndrome. Doesn't work with [email protected] but appending "-l user" works fine if needed. Works for ping as well.. complete -W "$(echo `cat ~/.ssh/known_hosts | cut -f 1 -d ' ' | sed -e s/,.*//g | uniq | grep -v "\["`;)" ping

Append stdout and stderr to a file, and print stderr to the screen [bash]
Useful for cron jobs -- all output will be logged but only errors will cause email to be sent. NB the order of "2>&1" and ">> logfile" is important, it doesn't work if you reverse them (everything goes to the logfile, nothing left for tee).

Get the size of all the directories in current directory

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

Recursively replace a string in files with lines matching string
Changed out the for loop for an xargs. It's a tad shorter, and a tad cleaner.

Change the homepage of Firefox
Pros: Works in all Windows computers, most updated and compatible command. Cons: 3 liner Replace fcisolutions.com with your site name.

history autocompletion with arrow keys
This will enable the possibility to navigate in the history of the command you type with the arrow keys, example "na" and the arrow will give all command starting by na in the history.You can add these lines to your .bashrc (without &&) to use that in your default terminal.
