Trap command problem
I am having a unix script which in turns calls another unix script.
Both are creating some temp files in /tmp which are supposed to be deleted after the end of each run

In the child script if I have statement like

trap "rm -f $messagefile" EXIT

A similar statement is there in parent script.


In case of error, although the trap command in child script is working fine but the trap command in parent script is not working.

Is there anyway through which I can return some signal/error exit code from child script's trap statement so that parent works.

Provide at least the shell of the code you are using.

Using the process ID of the parent, send kill -0 SIGNAL to the parent. Trap the signal in your handler. You will have to pass the value of the PID from parent to child when the child process is started.
