== How to edit a file on a server==

There are a number of common editors for editing files in a terminal.  The most frequently used are [http://www.nano-editor.org/dist/v2.0/nano.html nano], [http://vimdoc.sourceforge.net/htmldoc/usr_toc.html vim], [https://www.gnu.org/software/emacs/tour/ emacs].  Each of these editors comes with a level of difficulty, the easiest being nano.

To open a file with the respective editors, you will need to enter the following commands respectively:

 * nano /path/to/file
 * vim /path/to/file
 * emacs /path/to/file

Once a file is open you will need to know how to navigate within each program.  Please see the documentation.

 * Within nano get help by typing `Control+g`
 * Within vim get help by typing `: help` (that's the colon key then help.
 * Within emacs follow the tutorial with `Control+h t`.
