That IS a solution. It uses programming logic to decide what action to take, and those 'tricks' are used in MANY programs to make sure the required conditions are met before doing something. A commonly used program named passwd goes even further. It checks the user id and if not root it will only allow the user to change their own password. If root it allows the user to change any users password. When you write a script/program/procedure you must define the conditions that are required for satisfactory execution and also the actions to take if those conditions are not met. Any of the scripts in /etc/rc.d/init.d use similar logic to function. Check /etc/rc.d/init.d/network and you will see what I mean. In your case, since you do NOT want the script to execute unless the device is mounted, the suggestions you have received of how to check if it is mounted are parameters of the condition required to be met before it can complete and becomes the (automated) solution to your problem, not a workaround. > thanks, > Alex >
