1 XZDIFF(1) XZ Utils XZDIFF(1)
6 xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
9 xzcmp [cmp_options] file1 [file2]
10 xzdiff [diff_options] file1 [file2]
11 lzcmp [cmp_options] file1 [file2]
12 lzdiff [diff_options] file1 [file2]
15 xzcmp and xzdiff invoke cmp(1) or diff(1) on files compressed with
16 xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed
17 directly to cmp(1) or diff(1). If only one file is specified, then the
18 files compared are file1 (which must have a suffix of a supported com-
19 pression format) and file1 from which the compression format suffix has
20 been stripped. If two files are specified, then they are uncompressed
21 if necessary and fed to cmp(1) or diff(1). The exit status from cmp(1)
22 or diff(1) is preserved.
24 The names lzcmp and lzdiff are provided for backward compatibility with
28 cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)
31 Messages from the cmp(1) or diff(1) programs refer to temporary file-
32 names instead of those specified.
