Hi All,

I want to know about what command i can use so that it should run the below mentioned line if somebody killed the process when i run my script...

the command to run once my script is killed is

\rm -rf $LOCKDIR

Thank you

You can use trap - but you cannot trap all signals

trap "rm -rf $LOCKDIR"  [signal to trap goes here, example INT for ctrl/c interrupt]

kill -l ( that is a lowercase ELL) will show the signal names on your system.

if i want to use the trap then where do i need to use that? before the script starts?

trap "cleanup; exit" 0 1 2 3 15
