Readme for sak-0.1.3.1

[back to package description]

sak

sak is a command-line tool for compression.

Installation

Binary Releases

You can find binaries for many platforms here.

Source

With cabal-install:

cabal install sak

Use

To convert compression format:

sak transcode sak-0.1.0.0.tar.gz sak-0.1.0.0.tar.lz

To recompress a file:

sak recompress binary.tar.zst --best

Bash Completions

To get bash completions in your current shell session:

eval "$(sak --bash-completion-script sak)"

You can put this in your ~/.bashrc or ~/.bash_profile as needed.

Manpages

man/sak.1 contains manpages for sak

Comparison

Features

sak has some features not present in most decompressors (such as lzip or zstd)

  • transcode - converts from one compressed format to another (streaming)
  • recompress - loads a file into memory and compresses it at a higher level
  • verify - simply verifies that a file is valid

Performance

Performance should be on the same order of magnitude as the various C command-line tools (gzip, lzop, zstd, &c.).
