Fix Ubuntu's Broken Sound Server
Ever since the switch to pulseaudio, Ubuntu users including myself have found themselves with no sound intermittently. To fix this, just use this command and restarts firefox or mplayer or whatever.

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"

Write comments to your history.
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.

Create an alias, store it in ~/.bash_aliases and source your new alias into the ~/.bashrc
This is useful if you use a shell with a lot of other users. You will be able to run "topu" to see your running processes instead of the complete 'top -u username'. Read more on alias: http://man.cx/alias

Change display resolution
-s must be a valid resolution. You can get a list of valid (and supported) resolutions via `xrandr`.
