lz4

Format

cg lz4 ?options? file ...

Summary

Compresses files using lz4

Description

The given files are compressed using lz4, and the original uncompressed files are removed (by default). Files already compressed using another method, are recompressed using lz4. lz4 is a fast compression method, it compresses and decompresses an order of magnitude faster than gzip, at the cost of some compression.

Options

supports options:

-k 0/1 (--keep)

keep the original uncompressed file if 1 (default 0)

-c number (--compressionlevel)

number between 1 and 12 indicating compression level, where 1 = fast compression, 9 = high compression (default 9) At high compression (9), compression level and speed is similar to gzip, but decompression is still an order of magnitude faster

-b number (--blocksize)

number indicating the blocksize where: 4 = 64KB, 5 = 256KB, 6 = 1MB, 7 = 4MB (default 5)

-i 0/1 (--index)

also create an lz4 index file

-o filename (--outputfile)

The compressed file will be written to filename. If the --keep option is not explicitely given, using -o will change the "default" for -k to 1.
