How to kill background jobs? (kill %1 doesn't work)

[jackhab]

I have a FIFO file I'm reading in a background loop:

while (true) ; do cat </tmp/ui-output ; done &

I close the terminal, open another one, run this line again. After a while a have several 'cat /tmp/ui-output' processes running. Now I want to clean up the mess. When I run jobs in a new terminal it shows nothing. When I'm trying to kill by PID the processes are getting re-spawned:

$ ps -o pid= -C 'cat /tmp/ui-output' 
29773
29774
29775
29776

$ ps -o pid= -C 'cat /tmp/ui-output' | xargs kill

$ ps -o pid= -C 'cat /tmp/ui-output' 
29783
29785
29787
29788

How do I catch them?
Thanks.

Hi

Try this

top

It will give you list of the list of programs running on your system with pid and command (program name)

the select the program you want to kill note down its pid
then pass this command

kill -9 pid

hope this will help

Thanks. I forgot kill sends TERM signal by default while I needed KILL.
