When you’re running a long command on a terminal over SSH, illness you may end up wasting a great deal of time checking back repeatedly to see if the process is complete. A quick alternative would be to make the shell beep when it’s complete. Assuming you are running a script called “longScript.sh”, then simply typing a line like:
> longScript.sh; printf \a
Will cause most SSH clients to beep after longScript.sh is finished running.

Hope that helps!
