       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  uncompressed 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
       compressors are bzip2, gzip, lzip and xz.

       Compares <file1> to <file2>. If <file2>  is  omitted  zdiff  tries  the
       following:  If <file1> is compressed, compares <file1> to the file with
       the corresponding decompressed file name (removes  the  extension  from
       <file1>).   If  <file1>  is  not  compressed,  compares  <file1> to the
       uncompressed contents of <file1>.[bz2|gz|lz|xz] (the first one that  is
       found).   If  no  suitable file is found, compares <file1> to data read
       from standard input.

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