Any linux command to perform parallel decompression of tar.bz2 file?

rated 0 times [ 24] [ 0] / answers: 1 / hits: 28421 / 2 Years ago, sat, june 18, 2022, 2:04:02

I have a rather large file (~50GB) and it takes some time to run

tar xvf file.tar.bz2

on it. I'm aware of programs that can do parallel compression for bzip2 files but unaware of programs that can do parallel decompression for bzip2 files.

Are there any programs that can achieve this? What is the exact syntax of the command to use to extract from the file?

I'm using ubuntu 12.04

lbzip2 and pbzip2 are the tools which you can use for parallel compression and decompression.

Usage:

lbzip2 -d <file.tar.bz2> 

pbzip2 -d <file.tar.bz2>

-d option is used for decompression.

To install these packages:

lbzip2 type:

sudo apt-get install lbzip2

pbzip2 type:

sudo apt-get install pbzip2
