## 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.

## 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.
