Kill a process launched by a shell script


I have a script "A.sh". It will launch a automated SSH process.

However, sometimes, the SSH process get hanged.

I try to kill the script A.sh, but, the hanged SSH process is still alive.

I hope that if I kill the A.sh, the child SSH process can also be killed together?

(Maybe, getting the PID of the child SSH process, then kill it? I don't know how to write)

Get the process ID using ps -u <username>

Then kill the process using kill -9 <process_id>

Or, the "faster" alternative,
skill
... or ...
fuser -k

Both will allow you various ways of killing
stuff, eg username, process name, ... saving
you looking up the PID.

E.g. skill -KILL nutscrape joe_blogg


Cheers,
Tink

skill is a quite powerful tool

But it needs me to give a signal name to it e.g. HUP, KILL.
I don't know what are they. Which website could teach me these things?
(I have try to search the google like "linux signals, HUP, KILL", but those pages are not talking about these things)

Thanks.

Just try a
man skill
in a terminal :)

It will give you all the details (well, almost) ...
and the ones it doesn't - it gives you other
references for ;) ... after 30 seconds of reading
(jump to end of man page, read SEE ALSO)
you'll come across
man 7 signal



Cheers,
