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

<para>The <filename>/etc/inputrc</filename> file deals with mapping
the keyboard for specific 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 the <command>bash</command> info page, section
<emphasis>Readline Init File</emphasis>. The
<filename class="libraryfile">readline</filename> info page is
also a good source of information.</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 Bash 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). To make
the system use both, or to negate global 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
cannot be on the same line as commands.</para>

<para>To create the <filename>.inputrc</filename> in <filename
class="directory">/etc/skel</filename> using the command below, change
the command's output to <filename
class="directory">/etc/skel/.inputrc</filename> and be sure to
check/set permissions afterward. Copy that file to
<filename>/etc/inputrc</filename> and the home directory of any user
already existing on the system, including <emphasis>root</emphasis>,
that needs a private version of the file. Be certain to use the
<parameter>-p</parameter> parameter of <command>cp</command> to
maintain permissions and be sure to change owner and group
appropriately.</para>
