Save and clear the terminal contents with: $tput smcup Execute some commands, then restore the saved terminal contents with: $tput rmcup

Command to logout all the users in one command
This command logs out all users - which is way more secure to use ps -ef and "grep" to kill processes. Never ever use ps -ef piped to grep to kill something. If you ever need to ps-something use the UNIX95-directive, which makes sure you will never need "grep" together with "ps".

Have to run as superuser... but easier and more informational if you are looking for actual devices. Need to install arp-scan.
