Logging Off Students

• I wrote a script named superkill that teachers can use to logoff students. All they need to do is logon to Jill and type

  	./superkill studentID
  

  where studentID is the student they want to logoff.
• Here is the code for the script:

  #!/bin/sh
  for i in $(pgrep -u $1)
  do
      kill -9 $i
  done
