# shell_default

### MODULE

shell_default

### MODULE SUMMARY

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 called `user_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.
