How to send a signal SIGINT from script to script ? BASH
- by debugger
I want to trap a signal send from Script-A.sh to Script-B.sh
so in Script-A.sh i use the command
(Send SIGINT to Script-B.sh)
kill -2 $PID_Script-B.sh
And in Script-B.sh i catch the signal and call function Clean
trap 'Clean' 2
It does not work, instead the Script-B.sh is killed right away without performing the Clean !!
What i notice also is that if i want to send SIGINT from terminal to any script that traps it, a ctrl-c will be catched correctly, but not if i specify the signal via the command kill -2 $pid_of_script
Any idea about the difference between the two method to send the SIGINT (ctrl-c VS kill -2 $pid_of_script), and how i can send a SIGINT from a script to another ?
