I have a zip file that I need to extract into another folder. When I set up extraction to said folder it says "permission denied". I've read here how to log into a terminal as root and superuser but can't find anything to help me.
I need to extract a file from my Downloads directory to /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-ins.
Please explain how to extract a zip file to the correct folder.
