ZDIFF(1)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 one file is specified, then it is compared to a file
with the same name without the .gz extension. If two files are speciā
fied, then they are uncompressed if necessary and fed to cmp or diff.
The exit status from cmp or diff is preserved.
When both files must be uncompressed before comparison, the second is
uncompressed to /tmp. In all other cases, zdiff and zcmp use only a
pipe.

Messages from the cmp or diff programs refer to temporary filenames
instead of those specified.
