Changing the default text editor on Linux to Nano.
The default command line text editor in shell on Linux BSD determines what is used when you run commands such as "crontab -e" and this is often not what you want to use. Typically vi/vim is the default text editor.
First make sure Nano is installed by running this command:
yum install nano
While you are there, you might want to download these common tools for CentOS as well:
yum install nano wget curl net-tools lsof bash-completion
We prefer to use Nano which can be enabled with one simple code.
export EDITOR=nano
