lrzip
designed for compressing large files
TLDR
Compress with LZMA (default)
$ lrzip [path/to/file]
Compress with BZIP2$ lrzip --bzip2 [path/to/file]
Compress with ZPAQ (extreme)$ lrzip --zpaq [path/to/file]
Compress with LZO (fast)$ lrzip --lzo [path/to/file]
Encrypt compressed file$ lrzip --encrypt [path/to/file]
Set thread count$ lrzip --threads 8 [path/to/file]
SYNOPSIS
lrzip [options] [file]
DESCRIPTION
lrzip (Long Range ZIP) is designed for compressing large files. It uses long-range redundancy reduction followed by compression, achieving high ratios on files with distant matching data.
PARAMETERS
-b, --bzip2
Use BZIP2 compression (balanced)-z, --zpaq
Use ZPAQ compression (maximum, slow)-l, --lzo
Use LZO compression (fast)-g, --gzip
Use GZIP compression-e, --encrypt
Encrypt with password-p, --threads N
Number of processor threads-o, --outfile FILE
Specify output filename-k, --keep
Keep original file
CAVEATS
Very effective on large files with redundant data. ZPAQ compression is extremely slow but achieves best ratios.
