Short answer:

pkill -a Terminal

Slightly longer answer:

The above command search all processes which have the name "Terminal" in them and kill them. This will kill the shell process (e.g. bash) and any processes in the same process tree (commands run under the control of the shell). It probably won't kill GUI applications since they often double fork. Since these are no longer associated with the Terminal process, it's not possible to figure out which ones were originally launched by the terminal.

Also, to find the process without killing it, run:

pgrep -a Terminal

How about cmd+q? It closes the application and all windows of it. If you can send keyboard command.

• It will ask you if you want to terminate all processes before closing all terminals.
• It does not re-open all closed terminals on next launch.
