#TIL : Compressing and Extracting files with rar in Linux

zip and tar disadvantages

All unicode filename will be transform to weird character, so it makes broken paths and broken links

Notice

rar and unrar in Linux isn't same version and so don't use unrar to extract archived file by rar (It causes invalid full paths)

Installation

Ubuntu :

$ sudo apt install rar

Redhat ( using RPMForge )

$ sudo yum install rar
