LINUX - UBUNTU Shell Script

Task 1 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 <username> : Disables (locks), but does not remove the specified user account => user cannot use disabled account for login
• disableuser.sh -m <username> <'message'> : Does not disable login (by the operating system), but changes the user's login shell to a script that just writes the quoted message to standard output and then exits

Example results:

o   whoami -> student1

o   disableuser.sh -m user1 'You have been terminated'

o   su user1 -> 'You have been terminated'

o   whoami -> student1

Your disableuser.sh script will have to:

o   Generate the special login script that incorporates the quoted message

o   Configure user account to use the special login script

 

Task 2 description: Design and implement the removeuser.sh script.

  • Then, removes the user account
