sharc

Simple High-speed ARChiver

sharc is a very fast file archiver, using the density compression library. It is ideal when speed is the main requirement, followed by compression ratio - although excellent ratios can be achieved with certain settings and low entropy data.

Build

Usage

To compress a file named 'test' using the default algorithm (density cheetah):

sharc test

To decompress 'test.sharc',

sharc -d test.sharc

or:

unsharc test.sharc

Compression algorithm can be selected with the -c option. Fastest algorithm (density chameleon):

sharc -c1 test

Well-balanced default (density cheetah)

sharc -c2 test

Slower but still very fast, with better compression ratio (density lion):

sharc -c3 test
