zcmp

ZDIFF(1)						      General Commands Manual							  ZDIFF(1)

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  con-
       tents  (uncompressed  if  necessary)  are  fed to cmp or diff.  The input files are not modified.  The exit status from cmp or diff is pre-
       served.

SEE ALSO

       cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)

BUGS

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