Oracle Java download from command line
Friday, February 12. 2016
As Linux system administrator every once in a while you need to install something requiring Java. Open-source guys tend to gear towards OpenJDK, the GPL-licensed version of java. Still, java developers tend to write a lot of crappy code requiring a specific version of run-time-engine. So, you're in a desperate need of Oracle's java.
Now the Oracle people are very keen on you accepting their license before you can get your hands on their precious, leaky, JRE. At the same time all you have in front of you is a Bash-prompt and you're itching to go for a:
wget http://download.oracle.com/otn-pub/java/jdk/8u74-b02/jre-8u74-linux-x64.rpm
Yes. Everybody has tried that. No avail. 
All you're going to get with that is a crappy HTML-page saying, that you haven't approved the license agreement and your request is unauthorized.
Darn!
But wait! There is a solution! All the Oracle is looking to see is a specific cookie oraclelicense set with a value accept-securebackup-cookie.
So, to leech the file into your box, you can do a:
wget --header='Cookie: oraclelicense=accept-securebackup-cookie' http://download.oracle.com/otn-pub/java/jdk/8u74-b02/jre-8u74-linux-x64.rpm
Ta daa! No you're rocking.
