Unrar via terminal.

On a mac, to extract a rar compressed file, you can simply use a free tool called Unrar X. Get it here.

I have most of my rar compressed files on my remote server though, so I can avoid using a GUI program by invoking a terminal command via ssh which goes like this: $ unrar x <path-to-rar> <path-to-extract>

Sometimes I encounter rar files which are password protected. No problem for unrar via commandline. Just use the “-p” switch:
$ unrar x -p <path-to-rar> <path-to-extract>
