Inside the zip file there are 2 directories/folders, 'opt' and 'usr'. These 2 directories need to be moved to the folder /root. The KR file will be in the scripts folder within opt All that command I gave you did was copied the folder '/home/user/MyDocs/opt' and '/home/user/MyDocs/usr' (which you said you had extracted to MyDocs ) to /root The next command changed directory to /root/opt/scripts The next command makes KR executable Nowhere in there was an unzip/extract command
