NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
SYNOPSIS
xzcmp [cmp_options] file1 [file2]
xzdiff [diff_options] file1 [file2]
lzcmp [cmp_options] file1 [file2]
lzdiff [diff_options] file1 [file2]
DESCRIPTION
xzcmp and xzdiff invoke cmp(1) or diff(1) on files compressed with
xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed
directly to cmp or diff. If only one file is specified, then the files
compared are file1 (which must have a suffix of a supported compression
format) and file1 from which the compression format suffix has been
stripped. If two files are specified, then they are uncompressed if
necessary and fed to cmp(1) or diff(1). The exit status from cmp or
diff is preserved.
The names lzcmp and lzdiff are provided for backward compatibility with
LZMA Utils.

BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary
filenames instead of those specified.
