|

6 | <application>vim</application> as its editor. At this point we should
|

7 | state that there are a <emphasis>lot</emphasis> of different editors out
|
---|
8 | there including <application>emacs</application>,
|
---|
9 | <application>nano</application>, <application>joe</application> and many
|
---|
10 | more. Anyone who has been around the Internet (especially usenet) for a
|
---|
11 | short time will certainly have observed at least one flame war, usually

12 | involving <application>vim</application> and

13 | <application>emacs</application> users!</para>

15 | <para>The <acronym>LFS</acronym> book gives a basic <filename>vimrc
|
---|
16 | </filename> file. Here, we attempt to enhance this file. At startup,
|
---|
17 | <command>vim</command> reads <filename>/etc/vimrc</filename> and
|
---|
18 | <filename>~/.vimrc</filename> (i.e., the global
|
---|
19 | <filename>vimrc</filename> and the user-specific one.). Note that this is
|
---|
20 | only true if you compiled <application>vim</application> using
|
---|
21 | <acronym>LFS</acronym>-3.1 onwards. Prior to this,
|
---|
22 | the global <filename>vimrc</filename> was <filename>/usr/share/vim/vimrc
|
---|
23 | </filename>.</para>
|
---|
24 |
|
---|
25 | <para>Here is a slightly expanded <filename>vimrc</filename> that you can
|
---|
26 | put in <filename>/etc/vimrc</filename> to provide global effect. Of course, if
|
---|
27 | you put it into <filename>/etc/skel/.vimrc</filename> instead, it will
|
---|
28 | be made available to users you add to the system later. You can also copy
|
---|
29 | the file from <filename>/etc/skel/.vimrc</filename> to
|
---|
30 | <filename>/etc/vimrc</filename> and the home directory of users already
|
---|
31 | on the system, like root. Be sure to set permissions, owner and group if
|
---|
32 | you do copy anything directly from <filename>/etc/skel</filename>.</para>
