The dupatch utility provides a command-line interface that allows dupatch to be called by other programs. You can use the command line to invoke all functions except for baselining. The functions have the same operation and definition as the menu-driven interface. For information about using the command-line interface, see the dupatch(8) reference page, which is installed on your system when you install the patch-kit tools and is documented in this appendix.
You must specify all mandatory options on the command line or in a data file. If any mandatory option is missing, the command will fail with an appropriate error message; it will not prompt you for the missing option and information.
