lbzip2
TLDR
Compress file
$ lbzip2 [file]
Decompress file$ lbzip2 -d [file.bz2]
Use specific thread count$ lbzip2 -n [4] [file]
Keep original file$ lbzip2 -k [file]
Compress to stdout$ lbzip2 -c [file] > [file.bz2]
Test archive integrity$ lbzip2 -t [file.bz2]
SYNOPSIS
lbzip2 [options] [files...]
DESCRIPTION
lbzip2 is a parallel bzip2 compressor and decompressor. It uses multiple CPU cores to compress and decompress files faster than standard bzip2.
lbzip2 produces output compatible with bzip2/bunzip2. It automatically uses available CPU cores, making it much faster on multicore systems.
PARAMETERS
-d, --decompress
Decompress.-z, --compress
Compress (default).-k, --keep
Keep input files.-c, --stdout
Output to stdout.-t, --test
Test integrity.-n threads
Number of threads.-1 to -9
Compression level.-f, --force
Force overwrite.-v, --verbose
Verbose output.
COMPARISON
$ bzip2 - Single-threaded
pbzip2 - Parallel, different archive format
lbzip2 - Parallel, fully compatible format
pbzip2 - Parallel, different archive format
lbzip2 - Parallel, fully compatible format
CAVEATS
Higher memory usage than bzip2. Thread count affects memory. Compatible with bzip2 files. Default uses all cores.
HISTORY
lbzip2 was written by Mikolaj Izdebski as a drop-in parallel replacement for bzip2 that maintains full compatibility with the original format.
