Today, I’got some file .rar from my friend. But I simply can not extract it. I tough I can use unzip. Then I realize I must using unrar, this kind of archive is different with .zip.

In order, to install unrar, you must download rpm first.

# wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

Then, install the package

# rpm -Uvh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

After install the package, now you can install unrar.

# yum install unrar

Of course you must execute command above as root. How to extract? To open/extract a RAR file with their original directory structure, just issue command with unrar x option.

# unrar x somefile.rar

See manual for full hint :D This step work on RHEL6.
