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. + xzcmp and xzdiff compare uncompressed contents of two files. Uncom- + pressed data and options are passed to cmp(1) or diff(1) unless --help + or --version is specified. -SEE ALSO - cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zstd(1), zdiff(1) + If both file1 and file2 are specified, they can be uncompressed files + or files in formats that xz(1), gzip(1), bzip2(1), lzop(1), zstd(1), or + lz4(1) can decompress. The required decompression commands are deter- + mined from the filename suffixes of file1 and file2. A file with an + unknown suffix is assumed to be either uncompressed or in a format that + xz(1) can decompress. -BUGS - Messages from the cmp(1) or diff(1) programs refer to temporary file- - names instead of those specified. + If only one filename is provided, file1 must have a suffix of a sup- + ported compression format and the name for file2 is assumed to be file1 + with the compression format suffix removed. + The commands lzcmp and lzdiff are provided for backward compatibility + with LZMA Utils. +EXIT STATUS + If a decompression error occurs, the exit status is 2. Otherwise the + exit status of cmp(1) or diff(1) is used. + +SEE ALSO + cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zstd(1), lz4(1) -Tukaani 2021-06-04 XZDIFF(1) +Tukaani 2024-02-13 XZDIFF(1) |
