XZDIFF(1) XZ Utils XZDIFF(1)
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), bzip2(1), lzop(1), or zstd(1). All options
specified are passed directly to cmp(1) or diff(1). If only one file
is specified, then the files compared are file1 (which must have a suf-
fix of a supported compression format) and file1 from which the com-
pression 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(1) or diff(1) is preserved unless a decompres-
sion error occurs; then exit status is 2.
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 file-
names instead of those specified.
