To my surprise I found that there’s no usable unrar command on my RaspberryPi.
I run Raspbian on it and it so happens that I wanted to unpack a rather large rar file.
unrar-free package is not good enough for some archives, so that is not an option.
So how to get a working unrar on a Raspbian 8.0? And do you really need it?
Well, there are 2 options that I found, either you use 7zip or if you really want the unrar command, you can build it from Debian source package.
