rar file Operations under *NIX

What is RAR file:

RAR files are in compressed archive format, if you have downloaded rar files from the Internet, you need to unpack or unrar them (extract rar files). RAR is a proprietary file format for data compression and archiving, developed by Eugene Roshal.

RAR on *NIX:

Under *NIX (Any Linux or Unix variant), to extract RAR files you can use command called unrar. By default unrar is not being installed on *NIX OS. You can install unrar command with the help of apt-get or yum command. Don’t like these!😀. Don’t worry source file is always waiting for you to be downloaded at their site:-). So let’s go on with the proceedings guys.

Install unrar:

* Under Debian Linux variants, use apt-get:

# apt-get install unrar-free

Note that in case of Debian you have to install unrar-free.

* Using RHEL or Fedora ??? Go for yum then:

# yum install unrar

Special Note on Fedora Core:

You need to point out to use dag RPM Repository for unrar command under Fedora Core Linux. To do so do as following:

1. Put the following lines in /etc/yum.conf file:

[dag]
name=Dag RPM Repository for Fedora Core
baseurl=http://apt.sw.be/fedora/$releasever/en/$basearch/dag
gpgcheck=1
enabled=1

2. Import PGP key:

# rpm –import http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt

3. Upgrade your system:
# yum update

4. Install unrar:
# yum install unrar

Or just download the RPM file from dag site.

* On FreeBSD do:

# pkg_add -v -r unrar

* Unhappy with any of the methods above or it doesn’t suit you!!!

1. Download binary package from official rarlab site:
http://www.rarlab.com/download.htm

or do:

$ wget http://www.rarlab.com/rar/rarlinux-3.8.0.tar.gz

2. Untar file:

$ tar -zxvf rarlinux-3.8.0.tar.gz

3. Both unrar and rar commands are located in rar directory. Just go to rar directory:

$ cd rar
$ ./unrar

4. Copy rar and unrar to /bin or /usr/local/bin directory so that you don’t have to enter into the rar directory to run the executable file:

# cp rar unrar /bin

# cp rar unrar /usr/local/bin

Uses of unrar:

Below are common options that are used everyday.

* Open rar (unpack) file in current directory:

$ unrar e file.rar

Here replace file.rar with your actual filename.

* List (l) file inside rar archive:

$ unrar l file.rar

*Extract (x) files with full path:

$ unrar x file.rar

*Test (t) integrity of archive file:

$ unrar t file.rar

Hope these helps🙂
