Text Editors</a></h1><p>A lot of configuration in FreeBSD is done by editing text files. Because of this, itwould be a good idea to become familiar with a text editor. FreeBSD comes with a few aspart of the base system, and many more are available in the ports collection.</p><p>The easiest and simplest editor to learn is an editor called <bclass="APPLICATION">ee</b>, which stands for easy editor. To start <bclass="APPLICATION">ee</b>, one would type at the command line <tt class="COMMAND">ee<var class="REPLACEABLE">filename</var></tt> where <varclass="REPLACEABLE">filename</var> is the name of the file to be edited. For example, toedit <tt class="FILENAME">/etc/rc.conf</tt>, type in <tt class="COMMAND">ee/etc/rc.conf</tt>. Once inside of <tt class="COMMAND">ee</tt>, all of the commands formanipulating the editor's functions are listed at the top of the display. The caret <varclass="LITERAL">^</var> character represents the <b class="KEYCAP">Ctrl</b> key on thekeyboard, so <var class="LITERAL">^e</var> expands to the key combination <bclass="KEYCAP">Ctrl</b>+<b class="KEYCAP">e</b>. To leave <b class="APPLICATION">ee</b>,hit the <b class="KEYCAP">Esc</b> key, then choose leave editor. The editor will promptyou to save any changes if the file has been modified.</p><p>FreeBSD also comes with more powerful text editors such as <tt class="COMMAND">vi</tt>as part of the base system, while other editors, like <tt class="COMMAND">emacs</tt> and<tt class="COMMAND">vim</tt>, are part of the FreeBSD Ports Collection. These editorsoffer much more functionality and power at the expense of being a little more complicatedto learn. However if you plan on doing a lot of text editing, learning a more powerfuleditor such as <tt class="COMMAND">vim</tt> or <tt class="COMMAND">emacs</tt> will saveyou much more time in the long run.</p></div><div class="NAVFOOTER"><hr align="LEFT" width="100%" /><table summary="Footer navigation table" width="100%" border="0" cellpadding="0"cellspacing="0"><tr><td width="33%" align="left" valign="top"><a href="shells.html"accesskey="P">Prev</a></td><td width="34%" align="center" valign="top"><a href="index.html"accesskey="H">Home</a></td><td width="33%" align="right" valign="top"><a href="basics-devices.html"accesskey="N">Next</a></td></tr><tr><td width="33%" align="left" valign="top">Shells</td><td width="34%" align="center" valign="top"><a href="basics.html"accesskey="U">Up</a></td><td width="33%" align="right" valign="top">Devices and Device Nodes</td></tr></table></div></body></html>⌨️ 快捷键说明
