Use man ps to take a look at how to use ps in some advanced way. You are
required to create a shell script called advcps.
advcps will display a menu (using select command), letting a user choose the criteria
he/she prefers to display the information about all the processes running in the system.
advcps should provide the options to: (1) display all the processes based on the
alphabetical order of their creators; (2) display all the processes based on the size of
memory they are using (from high to low); (3) display all the processes based on the CPU
time they have consumed (from high to low); (4) display all the process based on their
priorities (from high to low).
advcps should also provide an option to let the user exit itself.

Code:

#!/bin/bash

       $VAR=VAR
       echo "Please enter the user's name"
       read VAR
      if  [ $VAR = 1 ] ; then

             top | grep $VAR
      else
            echo "Not have this user"
      fi

I make this code but they can't store the read varable to my top | grep $VAR,why
