21 `lz4` is a CLI based on `liblz4`, an extremely fast implementation of lossless compression algorith…
22 It provides a default compression speed of typically > 500 MB/s per core.
23 Speed can traded for higher compression ratio, by increasing the compression level parameter.
34   * `lz4 file.lz4` will default to decompression (use `-z` to force compression)
37      during compression or decompression of a single file
59     on successful compression or decompression, using `--rm` command.
98   `-z` can also be used to force compression of an already compressed
112   Benchmark mode, using `#` compression level.
122   Compression level, with # being any value from 1 to 12.
123   Higher values trade compression speed for compression ratio.
125   Recommended values are 1 for fast compression (default),
126   and 9 for high compression.
127   Speed/compression trade-off will vary depending on data to compress.
131   Switch to ultra-fast compression levels.
132   The higher the value, the faster the compression speed, at the cost of some compression ratio.
134   This setting overrides compression level if one was set previously.
135   Similarly, if a compression level is set after `--fast`, it overrides it.
138   Set highest compression level. Same as -12.
141   Use `#` threads for compression.
148   This option only works in combination with very high compression levels (>=10).
152   Compression and decompression must use the same dictionary to be compatible.
189   Blocks depend on predecessors (improves compression ratio, more noticeable on small blocks)
210   Use Legacy format (typically for Linux Kernel compression)<br/>
232   Delete source files on successful compression or decompression
