How to install 7zip to extract rar files

Solution 1:

I don't know why would you like specifically 7-zip's binary to extract RAR, but here we go:

To unrar files with... unrar:

sudo apt-get install unrar-free
unrar e some.rar

To extract rar files with 7-zip:

sudo apt-get install p7zip-full
7z x some.rar

e and x mean extract obviously.

Solution 2:

You may use p7zip. And you can install p7Zip using command : sudo apt-get install p7zip.

To extract RAR archives, you'll need to install package "p7zip-rar", too.

Install it using : sudo apt-get install p7zip-rar

Or you can get it done in single command : sudo apt-get install p7zip p7zip-rar

Read p7zip manual for more information: man p7zip
