       zdiff - decompress and compare two files line by line


       zdiff [options] file1 [file2]


       Zdiff  compares  two  files  ('-'  means  standard  input),  and if they differ, shows the
       differences line by line. If any given file is compressed,  its  decompressed  content  is
       used.  Zdiff  is a front end to the diff program and has the limitation that messages from
       diff refer to temporary filenames instead of those specified.

       The formats supported are bzip2, gzip, lzip and xz.

       Zdiff compares file1 to file2. If file2 is omitted zdiff tries the following:

              1.  If  file1  is  compressed,  compares  its  decompressed   contents   with   the
              corresponding uncompressed file (the name of file1 with the extension removed).

              2.  If  file1  is  uncompressed,  compares  it  with  the  decompressed contents of
              file1.[lz|bz2|gz|xz] (the first one that is found).

              3. If no suitable file is found, compares file1 with data read from standard input.

       Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.
