.SH NAME
shell_default \- Customizing the Erlang environment.
.SH DESCRIPTION
.LP
The functions in this module are called when no module name is specified in a shell command\&.
.LP
Consider the following shell dialog:
.LP
.nf

1> lists:reverse("abc")\&.
"cba"
2> c(foo)\&.
{ok, foo}
.fi
.LP
In command one, module \fIlists\fR\& is called\&. In command two, no module name is specified\&. The shell searches module \fIuser_default\fR\& followed by module \fIshell_default\fR\& for function \fIc/1\fR\&\&.
.LP
\fIshell_default\fR\& is intended for "system wide" customizations to the shell\&. \fIuser_default\fR\& is intended for "local" or individual user customizations\&.
.SH "HINT"

.LP
To add your own commands to the shell, create a module called \fIuser_default\fR\& and add the commands you want\&. Then add the following line as the \fIfirst\fR\& line in your \fI\&.erlang\fR\& file in your home directory\&.
.LP
.nf

code:load_abs("$PATH/user_default").
.fi
.LP
\fI$PATH\fR\& is the directory where your \fIuser_default\fR\& module can be found\&.
