<IMG SRC="images/05-57i.jpg"><P><B>xinit</B> <I>client option(s)</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>xinit</B> command launches the X Window System (as called from <B>startx</B>) and can also launch a first client in situations where a system cannot start X directly from <B>/etc/init</B>.</P>
<P>In most situations, however, you won’t be launching an application from the command line. In these situations, there’s a sequence of steps that <B>xinit</B> uses when starting X:</P>
<DL>
<DD><B>•</B> It first looks for a file called <B>.xinitrc</B>, which runs as a shell script to start client programs.
<DD><B>•</B> If this file does not exist, <B>xinit</B> uses <I>xterm -geometry +1+1 -n login -display :0</I> as a command line.
<DD><B>•</B> If no server program exists on the command line, <B>xinit</B> looks for <B>.xserverrc</B> in the user’s home directory.
<DD><B>•</B> If this file does not exist, <B>xinit</B> uses <I>X :0</I> as a default server.
</DL>
<P>When you set up an <B>.xserverrc</B> script, you must be sure to launch the read X server.</P>
<P>There’s a science to writing an <B>.xinitrc</B> if you choose not to use the mechanized tools for configuring X Window System. You must be sure that the applications launched in this file are run in the background, except for the last program (usually a window manager), which should run in the foreground in order to ensure that the script doesn’t fail.</P>
<P><FONT SIZE="+1"><B>xkill......<TT>Kill Client</TT></B></FONT></P>
<IMG SRC="images/05-58i.jpg"><P><B>xkill</B> <I>option(s)</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>xkill</B> command forces an X server to sever connections to clients. You can specify a program by a resource identifier. If you do not do this, <B>xkill</B> will display a little skull-and-crossbones cursor, and the window underneath this cursor of death will be killed when you click on it.</P>
