Command Line Interface

The Altair Accelerator products have a rich set of programs that can be run on the shell command line.

Each program performs a specific task and is controlled by a set of command line parameters. The programs provide a usage command when run with a -h parameter as a quick way to understand what each does and what parameters it takes.

This section describes the programs that a user will find useful. There are other programs described in the Developer and Admin manuals that are useful for their situations.
