#After choosing your Linux distribution To keep everything simple we are going to use Centos7 for these labseach lab, install the latest graphical version of that Linux OS.<br><br>This course is designed with a unit testing suite, which can be used to look at the scripts you write and give real-time feedback.<br>This feedback is not perfect, however it may offer some hints if you get stuck with a error. It can also be used to make sure you are on the right track, and show progress.<br><br>

#The first step is to update your entire system. Fedora uses a new package manager: it is based on <source>yum, yet it contains newer code and has more maintainer features as also contains improved features. It should work very similarly to the yum command, but check the man pages if you get confused:update</source>#Install extra packages for enterprise linux<source>dnf updateyum install epel-release </source>#Lets start installing Next install applications we need, first Python version 3 and version 2:<source>dnf yum install python34 python34-devel # Install python3 .4 and python3.4 development librariesyum install python python2 -devel # Install python3python2.5 7 and python2.7development libraries

#Next, you will install a couple of useful applications called '''tmux''' and '''screen'''. They are referred to as '''terminal multiplexers'''. If you plan to spend a lot of time in the terminal, this powerful tool will help you get it done. Lets install it and plan to use it later:<source>dnf yum install screen tmux && ln -s /usr/bin/true /etc/sysconfig/bash-prompt-screen

dnf yum install python-pip # Install python2.7 pipcurl -O https://bootstrap.pypa.io/get-pip.py # Download python3.4 pip installersudo /usr/bin/python3.4 get-pip .py # Install python3.4 pip</source><br>In the dictionary, "git" is defined as an unpleasant or contemptible person. In the IT inductory, industry on the other hand, '''Git''' refers to a version control system that allows you to track any changes made to files and programs. The benefit to using git is primarily found when it's used with multiple people, sharing and working on code together. While that is not how we will be using it in this course, you may find some benefits in using it for managing multiple versions of the same program or for backing up your code onto the internet.
