cd directory_path_name

Lets say for example, you want to install the software in the /usr/java/ directory, then type:

cd /usr/java/


 2. Move the .tar.gz archive binary to the current directory by typing 

mv “source directory path/file to be moved” “destination directory where the files has to be moved” 

mv /home/user_home/Downloads/jdk-8u101-linux-x64.tar.gz /user/java

(here user_home indicates the name of the loggedin user e.g  /home/john/Downloads, /home/sammy/Downloads etc.)


3. Unpack the tarball and install the jdk   

tar zxvf jdk-8u101-linux-x64.tar.gz

 Delete the .tar.gz file if you want to save disk space or move it to some other location.
