Task description: Design and implement the disableuser.sh script.

Required script functionality:

• disableuser.sh –v: prints the script version number and exits

• disableuser.sh –h: prints help content and exits

• disableuser.sh –m <’message’>: Does not disable login (by the operating system), but changes the user’s login shell to a script that just prepares the quoted message to standard output and then exits.
