rar and unrar

Install the Packages

On Linux, managing rar requires 2 packages. Hence, proceed to install them from your distribution. On Debian, it is:

$ sudo apt install rar unrar -y

Compress (Rar)

To compress the files, you use the rar command. A simple compression is:

$ rar a <rarfilename> <directory>

e.g.:

$ rar a docs.rar ./docs

Password Encrypted

To create a rar file with password encryption, use the -hp argument:

$ rar a -hp<password> <rarfilename> <directory>

e.g. with password 123456:

$ rar a -hp123456 docs.rar ./docs

Extract (Unrar)

To extract the rar package, you simply move the rar file into the designated directory (unrar will unpack right next to this file) and then use the unrar program:

$ unrar x <rar file>

e.g.

$ unrar x doc.rar

Password Encrypted

To supply the password, simply use -p argument:

$ unrar x -p<password> <rar file>

e.g. with password 123456:

$ unrar x -p123456 doc.rar

That's all about rar file in Linux.
