<title>Introduction to <application>Tcsh</application></title>

<para>The <application>Tcsh</application> package contains "an enhanced but completely compatible
version of the Berkeley Unix C shell (csh)".  This is useful as an
alternative shell for those who prefer C syntax to that of the bash
shell, and also because some programs require the C shell in order to
install.</para>

<title>Command explanations</title>

<para><command>ln -sf /usr/bin/tcsh /bin/csh</command>: The
<acronym>FHS</acronym> states that
if there is a <application>C</application> shell installed, there should be a symlink from
<filename>/bin/csh</filename> to it.  This creates that symlink.</para>
