22 | <para><filename>/etc/inputrc</filename> deals with the mapping of the
|
---|
23 | keyboard for certain situations. This file is the start-up file used by
|
---|
24 | <application>readline</application>, the input related library used by
|
---|
25 | <application>bash</application> and most other shells.</para>

26 |
|
---|
27 | <para>For more information see <command>info bash</command>—<emphasis
|
---|
28 | role="strong">Node: Readline Init</emphasis> file as well as
|
---|
29 | <command>info readline</command>. There is a lot that can be done with this
|
---|
30 | one rc file.</para>
|
---|
31 |
|
---|
32 | <para>Global values are set in <filename>/etc/inputrc</filename>.
|
---|
33 | Personal user values are set in <filename>~/.inputrc</filename>. The
|
---|
34 | <filename>~/.inputrc</filename> file will override the global settings
|
---|
35 | file. A later page sets up <application>Bash</application> to use
|
---|
36 | <filename>/etc/inputrc</filename> if there is no <filename>.inputrc</filename>
|
---|
37 | for a user when <filename>/etc/profile</filename> is read (usually at login).
|
---|
38 | If you want your system to use both, or don't want <emphasis>global</emphasis>
|
---|
39 | keyboard handling, it is a good idea to place a default
|
---|
40 | <filename>.inputrc</filename> into the <filename
|
---|
41 | class="directory">/etc/skel</filename> directory for use with new users.</para>
|
---|
42 |
|
---|
43 | <para>Below is a base <filename>/etc/inputrc</filename> along with
|
---|
44 | comments to explain what the various options do. Note that comments
|
---|
45 | can <emphasis>not</emphasis> be on the same line as commands.</para>
|
---|
46 |
|
---|
47 | <para>If you will create an <filename>.inputrc</filename> in
|
---|
48 | <filename class="directory">/etc/skel</filename> using the command below,
|
---|
49 | change the command's output to <filename>/etc/skel/.inputrc</filename> and
|
---|
50 | be sure to check/set permissions afterward. Then you can just copy that
|
---|
51 | file to <filename>/etc/inputrc</filename> and the home directory
|
---|
52 | of any user already existing in the system, including <systemitem
|
---|
53 | class="username">root</systemitem>, that needs
|
---|
54 | a private version of the file. Be sure to use the <option>-p</option>
|
---|
55 | parameter of <command>cp</command> to maintain permissions and be sure to
|
---|
56 | change owner and group appropriately.</para>
