cron/terminal/script/mount questions

Hi, I'm new to the board and I have what I hope is a simple questions for you gurus out there. I have Panther server running and I would like to setup a cron job to mount a remote drive so that I can run a backup on it and then have another script to unmount the drive when it's finished. What's the syntax for mounting and unmounting a drive in a script? Thanks in advance for any help. Jeff jeff_langston mac.com
