Step 1: Prerequisites
a) You should have a running Ubuntu or Debian Linux System. In this article, we are using Ubuntu 22.04 LTS system to showcase the installation and usage of bunzip2 utility. You might be using some different Ubuntu or Debian linux system.
b) You should have sudo or root access to run privileged commands.
c) You should have apt or apt-get utility available in your Server.
d) Minimum hardware requirements:-
- CPU: Any modern processor supported by Ubuntu and Debian Linux system would be enough.
- Memory: Although 512MB would be enough but I would recommend to use atleast 1GB of memory for better performance.
- Storage: The bzip2 package requires only 1MB of space but it also depends on size of compressed .bz2 file and extracted output.
Step 2: Update Your Server
Before installing any new package, it is always recommended to check and install all the latest available features and fixes using sudo apt update && sudo apt upgrade command as shown below. This will keep your system stable and secure.
cyberithub@ubuntu:~$ sudo apt update && sudo apt upgrade
Step 3: Install bunzip2
In the next step, you can install bzip2 package from default Ubuntu repo by using sudo apt install bzip2 command as shown below. This will download and install the package along with all its dependencies.
cyberithub@ubuntu:~$ sudo apt install bzip2 Reading package lists... Done Building dependency tree... Done Reading state information... Done The following packages were automatically installed and are no longer required: fakeroot g++ g++-11 gcc gcc-11 libalgorithm-diff-perl libalgorithm-diff-xs-perl libalgorithm-merge-perl libasan6 libcc1-0 libdpkg-perl libfakeroot libfile-fcntllock-perl libgcc-11-dev libitm1 liblsan0 libquadmath0 libstdc++-11-dev libtsan0 libubsan1 lto-disabled-list Use 'sudo apt autoremove' to remove them. Suggested packages: bzip2-doc The following NEW packages will be installed: bzip2 0 upgraded, 1 newly installed, 0 to remove and 62 not upgraded. Need to get 34.8 kB of archives. After this operation, 117 kB of additional disk space will be used. Get:1 http://in.archive.ubuntu.com/ubuntu jammy/main amd64 bzip2 amd64 1.0.8-5build1 [34.8 kB] Fetched 34.8 kB in 1s (67.3 kB/s) Selecting previously unselected package bzip2.

Setting up bzip2 (1.0.8-5build1) ... Processing triggers for man-db (2.10.2-1) ...
Step 4: Check Version
After successful installation, you can check current installed version by using bunzip2 --version command as shown below.
cyberithub@ubuntu:~$ bunzip2 --version bzip2, a block-sorting file compressor. Version 1.0.8, 13-Jul-2019. Copyright (C) 1996-2019 by Julian Seward. This program is free software; you can redistribute it and/or modify it under the terms set out in the LICENSE file, which is included in the bzip2 source distribution. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the LICENSE file for more details.
Step 5: Uncompress .bz2 file
Now that bunzip2 is installed, it is time to test this utility. We have an example bzip2 file called restic.bz2 which can be decompressed using bunzip2 restic.bz2 command as shown below. You will see that the extracted file will replace the original downloaded bzip2(.bz2) file.
cyberithub@ubuntu:~$ bunzip2 restic.bz2
If you are looking to retain the original bzip2 file along with the extracted file then you have to use -k option during decompression.
cyberithub@ubuntu:~$ bunzip2 -k restic.bz2
Step 6: Check all available options
You can check all options available with bunzip2 utility using bunzip2 --help command as shown below.
cyberithub@ubuntu:~$ bunzip2 --help bzip2, a block-sorting file compressor. Version 1.0.8, 13-Jul-2019. usage: bunzip2 [flags and input files in any order] -h --help print this message -d --decompress force decompression -z --compress force compression -k --keep keep (don't delete) input files -f --force overwrite existing output files -t --test test compressed file integrity -c --stdout output to standard out -q --quiet suppress noncritical error messages -v --verbose be verbose (a 2nd -v gives more) -L --license display software version & license -V --version display software version & license -s --small use less memory (at most 2500k) -1 .. -9 set block size to 100k .. 900k --fast alias for -1 --best alias for -9 If invoked as `bzip2', default action is to compress. as `bunzip2', default action is to decompress. as `bzcat', default action is to decompress to stdout. If no file names are given, bzip2 compresses or decompresses from standard input to standard output. You can combine short flags, so `-v -4' means the same as -v4 or -4v, &c.
Step 7: Uninstall bunzip2
Once you are done using bunzip2 utility, you can choose to remove it from your system by using sudo apt remove bzip2 command as shown below. To remove all dependencies installed with bzip2 package, use --auto-remove option with below command.
cyberithub@ubuntu:~$ sudo apt remove bzip2 Reading package lists... Done Building dependency tree... Done Reading state information... Done The following packages were automatically installed and are no longer required: fakeroot g++ g++-11 gcc gcc-11 libalgorithm-diff-perl libalgorithm-diff-xs-perl libalgorithm-merge-perl libasan6 libcc1-0 libdpkg-perl libfakeroot libfile-fcntllock-perl libgcc-11-dev libitm1 liblsan0 libquadmath0 libstdc++-11-dev libtsan0 libubsan1 lto-disabled-list Use 'sudo apt autoremove' to remove them. The following packages will be REMOVED: build-essential bzip2 dpkg-dev file-roller gnome-shell-extension-desktop-icons-ng ubuntu-desktop ubuntu-desktop-minimal 0 upgraded, 0 newly installed, 7 to remove and 62 not upgraded.
