Editing configuration files with nano

There are many different tools that you can use to edit configuration files. Because of its simplicity, I personally like to use Nano:

user@ubuntu:~$ sudo nano /path/to/the/file

You can change the default settings for nano by editing its configuration file. For example, to stop nano from wrapping text simply make the following changes to /etc/nanorc:

## Don't wrap text at all.
set nowrap
