<para><filename>/etc/inputrc</filename> deals with the mapping of the
|
|
keyboard for certain situations. This file is the start-up file used by
|
|
<application>readline</application>, the input related library used by
|
|
<application>bash</application> and most other shells.</para>
|
|
|
|
<para>For more information see <command>info bash</command>—<emphasis
|
|
role="strong">Node: Readline Init</emphasis> file as well as
|
|
<command>info readline</command>. There is a lot that can be done with this
|
|
one rc file.</para>
|
|
|
|
<para>Global values are set in <filename>/etc/inputrc</filename>.
|
|
Personal user values are set in <filename>~/.inputrc</filename>. The
|
|
<filename>~/.inputrc</filename> file will override the global settings
|
|
file. A later page sets up <application>Bash</application> to use
|
|
<filename>/etc/inputrc</filename> if there is no <filename>.inputrc</filename>
|
|
for a user when <filename>/etc/profile</filename> is read (usually at login).
|
|
If you want your system to use both, or don't want <emphasis>global</emphasis>
|
|
keyboard handling, it is a good idea to place a default
|
|
<filename>.inputrc</filename> into the <filename
|
|
class="directory">/etc/skel</filename> directory for use with new users.</para>
|
|
|
|
<para>Below is a base <filename>/etc/inputrc</filename> along with
|
|
comments to explain what the various options do. Note that comments
|
|
can <emphasis>not</emphasis> be on the same line as commands.</para>
|
|
|
|
<para>If you will create an <filename>.inputrc</filename> in
|
|
<filename class="directory">/etc/skel</filename> using the command below,
|
|
change the command's output to <filename>/etc/skel/.inputrc</filename> and
|
|
be sure to check/set permissions afterward. Then you can just copy that
|
|
file to <filename>/etc/inputrc</filename> and the home directory
|
|
of any user already existing in the system, including <systemitem
|
|
class="username">root</systemitem>, that needs
|
|
a private version of the file. Be sure to use the <option>-p</option>
|
|
parameter of <command>cp</command> to maintain permissions and be sure to
|
|
change owner and group appropriately.</para>
