So then David S. Jackson (dsj@dsj.net) said . . .

Okay, I get it now.  It's more similar to the SysV way than I thought:

su root -c "$mountcmd $device $mountpt"

So, this should work:


===SNIP===

#! /bin/sh

device="/dev/wcd0c"
mountpt="/cdrom"
ftpmountpt="/home/ftp/pub/cdrom"
mntcmd="mount -t cd9660"

case $1 in

    -f)
	su root -c "$mntcmd $device $ftpmountpt"
	;;
    -l)
	mount
	;;
    -u)
	check=$(mount | grep /cdrom)
	check1=$(mount | grep /home/ftp/pub/cdrom)
	check2=$(mount | grep /dev/wcd0c)
	if [ -n "$check" ]; then
	    echo "unmounting $check"
	    su root -c "umount $device"
	elif [ -n "$check1" ]; then
	    echo "unmounting $check1"
	    su root -c "umount $device"
	elif [ -n "$check2" ]; then
	    echo "unmounting $check2"
	    su root -c "umount $device"
	else
	    echo "$device is not mounted"
	fi
	;;
    -m)
	su root -c "$mntcmd $device $mountpt"
	;;
     *)
	echo -e "usage: cdm -f (for ftp users: requires root access) \n or -l (to show mounted directories) \n or -u (to umount /dev/wcd0c: requires root access) \n or * (to show this help resource) \n or -m (to mount to normal mount position: /cdrom  -- Requires root access)"
 
esac

===SNIP===

Let me know what you think!  :-)
