Ok im already having trouble. I can create a file that lists all the users; I know that I should use cmp to tell if the files are the same, but I do not know how to set up the while loop take each username in the file and then use it in the iff statement. I know I have to use a variable, but how do I get the while loop to transverse the file line by line?

DESCRIPTION

       Bzcmp  and  bzdiff  are used to invoke the cmp or the diff program on bzip2 compressed files.  All options specified are passed directly to

       then they are uncompressed if necessary and fed to cmp or diff.	The exit status from cmp or diff is preserved.
