It can be done with two shell scripts: No. 2 is run by No. 1 and exec's my program when No. 1 has finished doing it's stuff with the PID of No. 2. When my program finishes, No. 1 can remove the stuff it has done and exits. However, I am just writing a small C program which does this (by fork()) since this easier than havin two shell scripts talking with each other. -Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
