1 lz4(1) -- lz4, unlz4, lz4cat - Compress or decompress .lz4 files
7 `lz4` [*OPTIONS*] [-|INPUT-FILE] <OUTPUT-FILE>
9 `unlz4` is equivalent to `lz4 -d`
11 `lz4cat` is equivalent to `lz4 -dcfm`
14 it is recommended to always use the name `lz4` with appropriate arguments
15 (`lz4 -d` or `lz4 -dc`) instead of the names `unlz4` and `lz4cat`.
21 `lz4` is an extremely fast lossless compression algorithm,
23 `lz4` offers compression speeds > 500 MB/s per core,
27 The native file format is the `.lz4` format.
29 ### Difference between lz4 and gzip argument
31 `lz4` supports a command line syntax similar _but not identical_ to `gzip(1)`.
34 * `lz4` compresses a single file by default (see `-m` for multiple files)
35 * `lz4 file1 file2` means : compress file1 _into_ file2
36 * `lz4 file.lz4` will default to decompression (use `-z` to force compression)
37 * `lz4` preserves original files (see `--rm` to erase source file on completion)
38 * `lz4` shows real-time notification statistics
44 Otherwise, if `stdout` is the console, the implicit output is `filename.lz4`.
50 ensures that the output will be either the specified name, or `filename.lz4` respectively.
54 * `lz4 -m` makes it possible to provide multiple input filenames,
55 which will be compressed into files using suffix `.lz4`.
59 * Similarly, `lz4 -m -d` can decompress multiple `*.lz4` files.
62 * Consequently, `lz4 -m --rm` behaves the same as `gzip`.
64 ### Concatenation of .lz4 files argument
66 It is possible to concatenate `.lz4` files as is.
67 `lz4` will decompress such files as if they were a single `.lz4` file.
70 lz4 file1 > foo.lz4
71 lz4 file2 >> foo.lz4
73 Then `lz4cat foo.lz4` is equivalent to `cat file1 file2`.
99 (for example, a file extension `.lz4` implies `--decompress` by default).
101 `.lz4` file.
106 `.lz4` extension.
109 Test the integrity of compressed `.lz4` files.
117 List information about .lz4 files.
118 note : current implementation is limited to single-frame .lz4 files.
158 When used with `--decompress` and `lz4` cannot recognize the type of
161 that have not been compressed with `lz4`.
168 Compressed file names will be appended a `.lz4` suffix.
171 `lz4 -m` has a behavior equivalent to `gzip -k`
