<H3>MODULE SUMMARY</H3>
<UL>
Customizing the Erlang Environment</UL>
<H3>DESCRIPTION</H3>
<UL>
<P>The functions in <CODE>shell_default</CODE> are called when no module
name is given in a shell command.
<P>Consider the following shell dialogue:<PRE>1 > <STRONG>lists:reverse("abc").</STRONG>
"cba"
2 > <STRONG>c(foo).</STRONG>
{ok, foo}</PRE>
<P>In command one, the module <CODE>lists</CODE> is called. In command
two, no module name is specified. The shell searches the modules
<CODE>user_default</CODE> followed by <CODE>shell_default</CODE> for the
function <CODE>foo/1</CODE>.
<P><CODE>shell_default</CODE> is intended for "system wide"
customizations to the shell. <CODE>user-default</CODE> is intended for
"local" or individual user customizations.
</UL>
<H3>Hint</H3>
<UL>
<P>To add your own commands to the shell, create a module called
<CODE>user_default</CODE> and add the commands you want. Then add the
following line as the <STRONG>first</STRONG> line in your <CODE>.erlang</CODE> file in your
home directory. <PRE>code:load_abs("$PATH/user_default").</PRE>
<P><CODE>$PATH</CODE> is the directory where your
<CODE>user_default</CODE> module can be found.
