I need a script to check if a share is mounted. Lets call the server ABC and the share 123. I need a script to see if the share is mounted and if it is then call another script. If it is not mounted then the script should check to see if /mnt has a share mounted to it. If not then mount the share to /mnt. If /mnt is already used then check /tmp and mount to /tmp. If both /mnt and /tmp are already being used then exit and do nothing. Once the share is mounted then call another script.
