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
The zcmp and zdiff commands are used to invoke the cmp or the diff pro-
gram 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 pre-
served.

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