If the exit() occurs after system(), you can assume it will only be executed when B.pl exits for whatever reason.
Did you try to find out whether that is the case? |
B.pl is not a background mode, its a normal user script.
i qoute from perldoc for system "...Does exactly the same thing as exec LIST , except that a fork is done first, and the parent process waits for the child process to complete...." So i can take it that my first script will wait for B.pl to finish before exiting.
the perldoc entry for exec says " ..The exec function executes a system command and never returns--". Therefore i can assume that after it calls B.pl, the calling script will exit.
My intention is not to wait for B.pl to finish, ( ie, runs B.pl and the caller script itself exit ) therefore i should use exec? Any draw backs?
