SeeFEATURES andWHATS-NEW files for list of lrzip-next enhancements.

(See original README for more historical info)

$ git clone https://github.com/pete4abw/lrzip-next
or if you desire to also download thelrzip-fe front end
$ git clone --recurse-submodules https://github.com/pete4abw/lrzip-next

If you forget use --recurse-submodules and want to download lrzip-fe separately, use these commands:

$ git clone https://github.com/pete4abw/lrzip-next$ cd lrzip-next$ git submodule update --init (to download lrzip-fe)

NEW! Tarballs will now compile from version 0.7.44 onward. gitdesc.sh has been mademore intelligent! Recommend downloading from master, not from past tags/releases.

NEW! If you just want to trylrzip-next, download the static binaries. No compilationnecessary. Get current x86_64 binaries inReleases.

Verify file with gnupg key 0xEB2C5812.

cd lrzip-next$ ./autogen.sh$ ./configure [options] (see configure --help for all options)

If any required libraries or compilers are missing,configure will report and stop.

$ make [-j#] (for parallel make where # is typically number of processors)$ make install (as root)

lrzip-next applies a two-step process (optionally three-step process if filters are used)and reads file or STDIN input, passes it to therzip pre-processor (and optional filter).The rzip pre-processor applies long-range redundancy reduction and then passes the streams ofdata to a back-end compressor.lrzip--next will, by default, test each stream with acompressibilitytest usinglz4 prior to compression. The selected back-end compressor works on smaller datasets and ignore streams of data that may not compress well. The end result is significantlyfaster compression than standalone compressors and much faster decompression.

lrzip-next's compressors are:

• lzma (default)
• gzip
• bzip2
• bzip3
• lzo
• zpaq
• zstd
• rzip (pre-processed only)

lrzip-next's memory management scheme permits maximum use of system ram to pre-process files and then compress them.
