shell_default(3)

MODULE
shell_default - Customizing the Erlang Environment

DESCRIPTION

The functions in shell_default are called when no module name is given in a shell command.

Consider the following shell dialogue:
1 >lists:reverse("abc").
"cba"
2 >c(foo).
{ok, foo}

In command one, the module lists is called. In command two, no module name is specified. The shell searches the modules user_default followed by shell_default for the function foo/1.

shell_default is intended for "system wide" customizations to the shell. user_default is intended for "local" or individual user customizations.

Hint

To add your own commands to the shell, create a module calleduser_default and add the commands you want. Then add the following line as the first line in your .erlang file in your home directory.
code:load_abs("$PATH/user_default").

$PATH is the directory where your user_default module can be found.
