NAME

       zcmp, zdiff - compare compressed files

SYNOPSIS

       zcmp [ cmp_options ] file1 [ file2 ]
       zdiff [ diff_options ] file1 [ file2 ]

DESCRIPTION

       Zcmp  and zdiff are used to invoke the cmp or the diff program on files compressed via gzip.  All options
       specified are passed directly to cmp or diff.  If  only  file1  is  specified,  it  is  compared  to  the
       uncompressed  contents  of  file1.gz.   If  two  files  are  specified,  their  contents (uncompressed if
       necessary) are fed to cmp or diff.  The input files are not modified.  The exit status from cmp  or  diff
       is preserved.

BUGS

       Messages  from  the cmp or diff programs may refer to file names such as "-" instead of to the file names
       specified.
