           1. Write a shell script that will:

              Read your name from the standard input into a variable.

              Read your street address into a second variable.

              Read your city and state into a third variable.

              Print the contents of all the variables on the standard
              output and identify the output with headings.

              Put the shell program in a file named genlabel.

         
           2. Write a shell program that accepts a single argument. Search
              the output of the "who" command for the value of this argument.

              Put this shell program in a file called lookup.


              Example:

              $who
               alex      tty25    Apr 24 20:18
               hutch     tty15    Apr 24 21:22

              $lookup alex
               alex      tty25    Apr 24 20:18

              $lookup hutch
               hutch     tty15    Apr 24 21:22
