NAME

       zdiff - decompress and compare two files line by line

SYNOPSIS

       zdiff [options] file1 [file2]

DESCRIPTION

       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 supported formats are bzip2, gzip, lzip and xz.

       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.
