Compressing a file can significantly reduce the file size by encoding the data in the file with fewer bytes, and is useful when backing up and transferring files across the network. On the other hand, unzipping the file means restoring the data in the file to its original state.

There are several file compression and decompression tools in Linux, such as gzip, 7-zip, Lrzip, PeaZip, and so on.

In this tutorial, we will show you how to use the bzip2 tool to compress and extract .bz2 files in Linux.

Bzip2 is a very famous compression tool and is available on most major Linux distributions, so you can install it on your distribution with the appropriate command.

$sudo apt install bzip2 [On Debian/Ubuntu] $sudo yum install bzip2 [On CentOS/RHEL] $sudo dnf install bzip2 [On Fedora 22 +]

The general syntax for using bzip2 is:

$bzip2 option (s) filenames

How to use "bzip2" to compress files in Linux

You can compress a file as follows and use the-z flag to enable compression:

$bzip2 filename or $bzip2-z filename

To compress a .tar file, use the command:

$bzip2-z backup.tar

Important: bzip2 deletes the input file (the original file) by default when compressing and unzipping the file. To keep the input file, use the-k or-- keep option.

In addition, the-f or-- force flag forces bzip2 to overwrite existing output files.

-to keep the input file-$bzip2-zk filename $bzip2-zk backup.tar

You can also set the size of the block, from 100k to 900k, using-1 or-- fast to-9 or-- best:

$bzip2-K1 Etcher-linux-x64.AppImage $ls-lh Etcher-linux-x64.AppImage.bz2 $bzip2-K9 Etcher-linux-x64.AppImage $bzip2-kf9 Etcher-linux-x64.AppImage $ls-lh Etcher-linux-x64.AppImage.bz2

The screenshot below shows how to use the option to retain the input file, force bzip2 to overwrite the output file, and set the block size in compression.

How to use "bzip2" to extract files in Linux

To extract the .bz2 file, be sure to use the-d or-- decompress option:

$bzip2-d filename.bz2

Note: this file must be a .bz2 extension for the above command to be used.

$bzip2-vd Etcher-linux-x64.AppImage.bz2 $bzip2-vfd Etcher-linux-x64.AppImage.bz2 $ls-l Etcher-linux-x64.AppImage
