How do I kill a process once I've successfully identified the PID in a script?

Question

I have a bash script that needs to kill a specific PID that can be obtained by:

ps -A | grep -m1 apcagent | awk '{print $1}'

The above code identifies the PID of apcagent... and now I want to kill it within my bash script. Suggestions? Ideas?

Do you want to send a `SIGKILL` or a `SIGINT` signal to the process? — phoxis, May 10 '18 at 21:22

Thanks, Benjamin W. for the link. You're right, that question answered mine:

kill $(ps -A | grep -m1 apcagent | awk '{print $1}')

Also see `pidof`. You can do a `kill $(pidof processname)` – phoxis May 10 '18 at 21:23

It should be as easy as:

kill -9 <pid>

Did you look at man kill?

Don't use `-9` in everyday usage, as the process being killed doesn't get a chance to clean up after itself. `kill ` should be sufficient for a well-behaved program. – chepner May 10 '18 at 21:24
Agreed, @chepner – Tamias May 10 '18 at 21:29
