xzcmp [cmp_options] file1 [file2]
xzdiff [diff_options] file1 [file2]
lzcmp [cmp_options] file1 [file2]
lzdiff [diff_options] file1 [file2]
xzcmp and xzdiff invoke cmp(1) or diff(1) on files compressed with
xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1). All options specified
are passed directly to cmp(1) or diff(1). If only one file is speci-
fied, then the files compared are file1 (which must have a suffix of a
supported compression format) and file1 from which the compression for-
mat 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.
The names lzcmp and lzdiff are provided for backward compatibility with
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)
Messages from the cmp(1) or diff(1) programs refer to temporary file-
names instead of those specified.
