und command reference

und is Understand's command-line tool for creating and updating projects and running analysis, metrics, reports, and CodeCheck headlessly.

The complete per-command reference — every command with its synopsis, options, and examples — is generated from the product each release, so it always matches your build:

You can get the same content in your terminal:

und help              # list every und command
und help <command>    # full usage for one command, e.g. und help analyze

Task guides

For workflow-oriented guidance rather than raw command listings, see Automate & integrate:

• Run Understand from the command line (und) — the starting point.
• Headless workflow: create → analyze → check → report.
• Interactive mode & batch scripts.
• Configure settings & filter files.
