NAME

SYNOPSIS

9       zcmp [ cmp_options ] file1 [ file2 ]
10       zdiff [ diff_options ] file1 [ file2 ]
11

DESCRIPTION

13       The zcmp and zdiff commands are used to invoke the cmp or the diff pro‐
14       gram on files compressed via gzip.  All options  specified  are  passed
15       directly to cmp or diff.  If only file1 is specified, it is compared to
16       the uncompressed contents of file1.gz.  If  two  files  are  specified,
17       their contents (uncompressed if necessary) are fed to cmp or diff.  The
18       input files are not modified.  The exit status from cmp or diff is pre‐
19       served.

BUGS

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