# 2 Installation Verification

This chapter is about verifying your installation by performing a few simple tests to see that your system is properly installed.

### 2.1 UNIX

- Start Erlang/OTP from the command line,

        unix> erl

  Expect the following output:

        Erlang (BEAM) emulator version 5.0.1 [threads]

        Eshell V5.0.1  (abort with ^G)
        1>

- Start the GS-based toolbar from the Erlang shell,

        1> toolbar:start().

  and check that the toolbar window pops up.

  Note: The trailing full stop (".") is an end marker for all commands in the Erlang shell, and must be entered for a command to begin execution.

- Exit by entering the command halt(),

        2> halt().

  which should end both the toolbar window and the command line window.

### 2.2 Windows

- Start Erlang/OTP by double-clicking on the Erlang shortcut icon on the desktop.

  Expect a command line window to pop up with the following output,

        Erlang (BEAM) emulator version 5.0.1 [threads]

        Eshell V5.0.1  (abort with ^G)
        1>

- Start the GS-based toolbar from the Erlang shell,

        1> toolbar:start().

  and check that the toolbar window pops up.

  Note: The trailing full stop (".") is an end marker for all commands in the Erlang shell, and must be entered for a command to begin execution.

- Exit by entering the command halt(),

        2> halt().

  which should end both the toolbar window and the command line window.
