<title>Creating the /etc/inputrc file</title>

<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 root, that needs
a private version of the file.  Be sure to use the <parameter>-p</parameter> parameter
of <command>cp</command> to maintain permissions and be sure to change owner and group
appropriately.
