more newbie questions

Bit of a basic one this but show do I start a program like snort running only in a new terminal on its own without opening a new terminal specially to run one program.

there’s a couple of ways -
run it in the background by adding an & to the end of the command (./command &)
run it in screen. just run “screen”, use it as a normal terminal, then hit ctrl + A + D to detatch. type screen -r to re-attach
