xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
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
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(1) or diff(1) is
preserved.
The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.
