BMC Atrium Discovery provides utilities that you can run on a command line interface to configure Discovery by obtaining information from specific systems. All the utilities are located in the /usr/tideway/bin directory and are named tw_utilityname. Documentation for each utility in this section includes a link to the corresponding location in the user interface where you can perform the intended function.
 | Supported utilities All command line utilities that are supported in BMC Atrium Discovery are documented in this section. Any utility that is not documented in this section is an explicitly unsupported tool.

Duplicate or enhanced functionality in user interface
Many of the utilities perform functions that are already part the BMC Atrium Discovery user interface, and might duplicate what you might be able to accomplish more easily in the best-practice use of the product. Most of the configuration you perform will be done using the Discovery Configuration page accessed from the Administration tab; however, the functionality might be located in other areas of the product.
 | Note Although command line utilities offer a potentially faster or more convenient way to perform a specific function, they may also cause unintended consequences that might compromise your environment if not used carefully. |
Common options in the utilities
In each utility, you can specify options, or arguments, that enable you to specify what action you want the utility to perform. For many of the utilities, several options are inherited and their basic purpose does not change. In this section, common options are not described for each utility because they are not typically used.
The following table lists the common options that are inherited by many of the command line utilities available with BMC Atrium Discovery.

For more information about password policies, see Managing security policies. |
