Check These Out

move cursor to beginning of command line
Pressing Ctrl combined with 'a' will move the cursor to the beginning of the command under bash (other shells?). I used to do this after arrowing up for the last command, then typing 'sudo ' to run the last command as root, but of course the all time greatest command here `sudo !!` is more succinct. Still Ctrl+A can be very useful when you want to edit something at/close to the beginning of the command line.

kill ip connection
needed; apt-get install tcpkill

check open ports without netstat or lsof

Grep for word in directory (recursive)
greps for search word in directory and below (defaults to cd). -i case insensitive -n shows line number -H shows file name

What is my public IP-address?
alternative to $curl ifconfig.me for those that don't have curl

Nice info browser
pinfo package provide a nice info alternative based on ncurses.

Empty a file

Share your terminal session (remotely or whatever)
Force the user you want to watch doing things into doing his things in a screen session. Then simply attach yourself to that session with the command shown above. Works only if you are on the same machine, of course
