== How-to edit server.properties using vi ==

* The scope of this how-to is step 3 from basic steps.
* This how-to will cover changing maximum clients from 8 to 16.

'''<big>Step 1 - open server.properties file with vi</big>'''

<code>$ vi server.properties</code>

vi is a model editor that supports '''insert''' or '''command''' mode. insert mode is where typed text could become part of the file. command mode is where keystrokes are interpreted as commands that control the edit session.

Basic cursor movement in vi:
* <code>ESC</code> to enter command mode when in insert mode
* <code>i</code> to enter insert mode when in command mode
* <code>k</code> or <code>up arrow</code> to move up one line
* <code>j</code> or <code>down arrow</code> to move down one line
* <code>h</code> to <code>left arrow</code> move left one character
* <code>l</code> to <code>right arrow</code> move right one character
* <code>$</code> to move to end of line
* <code>r</code> replace single character under cursor (no <Esc> needed)
* <code>R</code> replace characters, starting with current cursor position, until <Esc> hit
* <code>u</code> undo last change
* <code>:x</code> save and exit file

'''<big>Step 2 - move cursor to max-players=8 line</big>'''

Move cursor down to line that starts with '''max-players=''' using <code>j</code> or <code>down arrow</code>. Your cursor should be over '''m''' in '''max-players'''.

'''<big>Step 3 - move cursor over 8</big>'''

Move cursor to right using <code>l</code> or <code>right arrow</code> until over the '''8'''.

'''<big>Step 4 - change 8 to 16</big>'''

Press <code>R</code> then type <code>16</code> and press <code>ESC</code>.

'''<big>Step 5 - save file and exit vi</big>'''

Press <code>:x</code> then press Enter.

'''<big>Step 6 - verify file was changed</big>'''

<code>$ grep players server.properties</code>

You should see '''max-players=16''' as part of output.
