Using IFHW

IFHW is used from a script file, in conjunction with other utilities, to control the deployment. The IFHW

utility enables you to make intelligent queries against the hardware discovery file. Queries take the form

of a logical expression, and the result of the expression is returned as the return code of the tool, which

the hosting script can use to conditionally perform actions.

IFHW command-line syntax

ifhw [drive:][path]hpdiscoveryfilename

[drive:][path]allboards.xml <expression>
