You can't. At some point you have to decompress them.

how bout..

Try Using diff , it will output a difference report containing the text that differs between the two files...

$ diff "file1" "file2" [RET] (of course don't use the ")

Maybe this will do!

Or perhaps not.

1. A compressed file is binary, diff is a text tool.

2. A tar file may contain the files in any order and still be considered the same.
