please post a video tutorial the tutorial says to type java in xterm after copying the extracted folder to home/opt/java. when i do that it tells me not found. 2. is it normal that i dont have the local/bin directory in /usr? 3.i changed the profile file just like in the tutorial. with an editor (windows). after that, when i type root or sudo gainroot in xterm i get an error? can someone give me the files ready so i just need to copy them? thx in advance
