【Linux】How to extract RAR files in CentOS/RHEL 7 and 8

There is no default utility in CentOS/RHEL 7 systems to extract a .rar file. This post outlines the steps to install the unar package and use of unar command to extract files with .rar extension.

  1. Log in as a root user (or use sudo) and configure the latest EPEL repositories to be able to install the unar package:
# yum install epel-release

Note: I recommend to disable all the existing repositories and just enable the EPEL repository if you do not want to face any conflict.

  1. Now you should be able to see the just configured repository:
# yum clean all
# yum repolist

You should be able to see the unrar package listed as well using the below command.

# yum info unar*

For example:

# yum info unar*
Loaded plugins: ulninfo
Available Packages
Name : unar
Arch : x86_64
Version : 1.10.1
Release : 1.el7
Size : 1.9 M
Repo : EPEL
Summary : Multi-format extractor
URL : http://unarchiver.c3.cx/commandline
License : LGPLv2+
Description : The command-line utilities lsar and unar are capable of listing and extracting
: files respectively in several formats including RARv3. unar can serve as a free
: and open source replacement of unrar.
  1. Now proceed to install the package:
# yum install unar -y
  1. Once the package is installed, now is possible to extract RAR files. Use the unrar command to extract the .rar files.
# unar [file_name.rar]

For example:

# ll
total 8
-rw-r--r--. 1 root root 72 May 6 10:48 test.rar
# file test.rar
test.rar: RAR archive data, v8, os: MS-DOS
# unar test.rar
test.rar: RAR 5
test.txt (0 B)... OK.
Successfully extracted to "./test.txt".
# ll
total 8
-rw-r--r--. 1 root root 72 May 6 10:48 test.rar
-rw-r--r--. 1 root root 0 May 6 10:48 test.txt

Note: View the man page of unrar command for more information and options available.

# man unrar

If you move the original repositories at the beginning of the post, move them back to original place and perform a “clean all”
