Get both PID and exit status of a child process
I have a C shell script on Linux that spawns a child process. If I run the child process in the foreground, I am able to capture its exit status via $status but not its PID. If I run it in the background (and force the parent to wait via the "wait" command) I am able to capture the PID of the child via $! but not the exit status. Both the $? and $status variables now hold the exit status of the "wait" command.
Any ideas? |
