Re: Cron Question?

The '*/8' syntax is not valid in HP-UX. That is a Linux only thing.

If you want to run A.pl at 8:49 and B.sh at 9:19, then:

49 8 * * * A.pl
19 9 * * * B.sh

Re: Cron Question?

Hi Allan:

The syntax you specified is a GNU (Linux) syntax not recognized by HP-UX.

You could have "script-A" 'sleep' for 1800 seconds (30-minutes) and thrn run "script-B" or you could have "script-A" issue:

at -f /home/script_B NOW +30 minutes

...to launch it.

Regards!
