installs Oracle Java 7

A quick tip for Debian users who want to install and stay up to date with the latest Oracle Java 7 (JDK7): the WebUpd8 Java 7 PPA works on Debian too since the package is just an installer and all you have to do is manually add the PPA repository to the Software Sources.

As a reminder, the Oracle Java 7 PPA repository does not host any Java files but only an installer that automatically downloads and installs Oracle Java 7, like the flashplugin-installer package for instance.

To add the WebUpd8 Oracle Java PPA repository to the Software Sources in Debian (tested on Debian Squeeze, but it should work with any Debian version), use the following commands:
su -
echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee -a /etc/apt/sources.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee -a /etc/apt/sources.list
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886
apt-get update
apt-get install oracle-java7-installer
exit

oracle java 7 debian

oracle java 7 debian

And that's it, Oracle Java 7 (both JDK7 and JRE7) should now be installed and you should receive automatic updates with future Oracle Java 7 versions, under Debian.

Update: the current JDK version in the PPA is Oracle Java 7 Update 10 (7u10).


Setting Java environment variables


To automatically set up the Java 7 environment variables, you can install the following package:
sudo apt-get install oracle-java7-set-default

If you've already installed oracle-java6-set-default or oracle-java8-set-default, they will be automatically removed when installing oracle-java7-set-default (and the environment variables will be set for Oracle Java 7 instead).

  https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into /opt/course/1/context_default_no_kubectl.sh , but without the use of k
