Ubuntu shell script - linux, Operating System

Assignment Help:

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 : Disables (locks), but does not remove the specified user account => user cannot use disabled account for login
  • disableuser.sh -m <'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:

1. whoami -> student1

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

3. su user1 -> 'You have been terminated'

4. whoami -> student1

Your disableuser.sh script will have to:

1. Generate the special login script that incorporates the quoted message

2. Configure user account to use the special login script

 

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

Required script functionality:

  • Disables (locks) the account username
  • Packs all files (not just those in the user's home directory) belonging to into single compressed archive named
  • Then, removes the user account
