So you must capture its exit value for the random number :).

I don't happen to have random installed on my system, however jot is installed with the base system, and will generate random numbers quite well. For example 'jot -r 1 1 60' will generate a single random number between 1 and 60. Won't randomNumber=$? Just return 0 if the previous command completes successfully? Shouldn't it be: randomNumber=`random -e 60` Or better yet randomNumber=`jot -r 1 1 60` ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

See 'man 6 random' and 'man sleep'. Then try doing something like this in the background: #!/bin/sh while true do random -e 60 randomNumber=$? sleep $randomNumber done Where '60' means, maximum 60 seconds between two script calls. There might be better or nices ways of doing this :).
