    <title>Configuring rxvt-unicode</title>

    <para>
      The <application>rxvt-unicode</application> terminal emulator uses the
      resource class <classname>URxvt</classname> and the resource name
      <classname>urxvt</classname>. You can add X resource definitions to a
      user's <filename>~/.Xresources</filename> or
      <filename>~/.Xdefaults</filename> files or to the system-wide
      <filename>/etc/X11/app-defaults/URxvt</filename> file. The following
      example will load the <classname>matcher</classname>
      <application>Perl</application> extension (assuming
      <application>Perl</application> support wasn't disabled), which enables
      a left button click to open an underlined URL in the specified browser,
      sets a background and foreground color and loads an Xft font (as the
      <systemitem class="username">root</systemitem> user):
    </para>

<screen role="root"><userinput>cat &gt;&gt; /etc/X11/app-defaults/URxvt &lt;&lt; "EOF"
<literal>! Use the specified colour as the windows background colour [default white]
URxvt*background: black

! Use the specified colour as the windows foreground colour [default black]
URxvt*foreground: yellow

! Select the fonts to be used. This is a comma separated list of font names
URxvt*font: xft:Monospace:pixelsize=18

! Comma-separated list(s) of perl extension scripts (default: "default")
URxvt*perl-ext: matcher

! Specifies the program to be started with a URL argument. Used by
URxvt*url-launcher: firefox

! When clicked with the mouse button specified in the "matcher.button" resource
! (default 2, or middle), the program specified in the "matcher.launcher"
! resource (default, the "url-launcher" resource, "sensible-browser") will be
! started with the matched text as first argument.
! Below, default modified to mouse left button.

      In order to view the defined X resources, issue:
    </para>

<screen role="nodump"><userinput>xrdb -query</userinput></screen>

      any on previously define), issue:

<screen role="nodump"><userinput>xrdb -merge ~/.Xresources</userinput></screen>

    <para>
      The <application>rxvt-unicode</application> application can also run
      in a daemon mode, which makes it possible to open multiple terminal
      windows within the same process. The <command>urxvtc</command> client
      then connects to the <command>urxvtd</command> daemon and requests a
      new terminal window.  Use this option with caution. If the daemon
      crashes, all the running processes in the terminal windows are
      terminated.
    </para>

    <para>
      You can start the <command>urxvtd</command> daemon in the system or
      personal startup <command>X</command> session script (e.g.,
      <filename>~/.xinitrc</filename>) by adding the following lines near the
      top of the script:
    </para>

<screen role="nodump"><userinput><literal># Start the urxvtd daemon
urxvtd -q -f -o &amp;</literal></userinput></screen>

    <para>
      For more information, examine the <command>urxvt</command>,
      <command>urxvtd</command>, <command>urxvtc</command>, and
      <filename>urxvtperl</filename> man pages.
