BDWB Shell Commands

Running BDWB

To run bdwb: switch to the directory where you want to begin creating the new application. You can run it one of two ways:

Batch Mode: You can run bdwb in a non-interactive mode directly from the command line, as described in Command Line Options, below.
Interactive: You can run bdwb using the interactive bdwb shell, as described in Interactive Commands, below.

Command Line Options

NOTE This section describes the options available in version 3.6 of the App Workbench.

You can run bdwb from the command line by executing either of the following commands:

bdwb -i <instruction>, where <instruction> is one of the commands described in Interactive Commands, below. The specified instruction executes immediately.
bdwb <file_name>.wb, where <file_name>.wb is the name of a Workbench file that contains instructions for non-interactive processing.
