Linux compression helper bzip2

Linux compression helper bzip2
GuideTo compress a file, you can use a small number of bytes to encode the data in the file to significantly reduce the file size, and it is useful for cross-network file backup and transfer. On the other hand, decompression means that the data in the file is restored to the initial state.

Linux has several File compression and decompression tools, such as gzip, 7-zip, Lrzip, and PeaZip.

In this tutorial, we will introduce how to use the bzip2 tool in Linux to compress and decompress the. bz2 file.

Bzip2 is a well-known compression tool available in most mainstream Linux distributions. you can install it with appropriate commands on your release.

$sudoaptinstallbzip2[OnDebian/Ubuntu]$sudoyuminstallbzip2[OnCentOS/RHEL]$sudodnfinstallbzip2[OnFedora22+]

The general syntax for using bzip2 is:

$bzip2option(s)filenames

How to use "bzip2" to compress files in Linux

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

$ Bzip2filename or $ bzip2-zfilename

To compress a. tar file, run the following command:

$bzip2-zbackup.tar

Important: bzip2 will delete the input file (original file) during File compression and decompression by default. to retain the input file, use the-k or -- keep option.

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

--------To reserve the input file ------20.bzip2-zkfilename1_bzip2-zkbackup.tar

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

$bzip2-k1Etcher-linux-x64.AppImage$ls-lhEtcher-linux-x64.AppImage.bz2$bzip2-k9Etcher-linux-x64.AppImage$bzip2-kf9Etcher-linux-x64.AppImage$ls-lhEtcher-linux-x64.AppImage.bz2

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

How to Extract files using "bzip2" in Linux

To decompress the. bz2 file, make sure to use the-d or -- decompress options:

$bzip2-dfilename.bz2

Note: This file extension is. bz2, which can only be used by the preceding command.

$bzip2-vdEtcher-linux-x64.AppImage.bz2$bzip2-vfdEtcher-linux-x64.AppImage.bz2$ls-lEtcher-linux-x64.AppImage

Decompress the bzip2 File in Linux

To view the bzip2 help and man page, enter the following command:

$bzip2-h$manbzip2

Finally, I believe that you can compress and decompress the bz2 file in Linux. However, if you have any questions or feedback, you can leave a message in the comment area.
