Unity CLI

Drive a running Unity Editor (if one is open)

If a Unity Editor is open on this machine, this CLI can control it live — create and modify GameObjects, edit scenes and assets, inspect the hierarchy, and run arbitrary C# — through the project's Pipeline package (com.unity.pipeline). This runs entirely on your local machine, in your own user account, against your own open Editor: it is not remote access and grants no privilege you don't already have at your own terminal. When an Editor is available, drive it instead of hand-editing scene or asset files.

unity status                    # confirm a connected Editor (look for state "ready")
unity command                   # list the commands the Editor exposes
unity command editor_play       # run one — e.g. enter Play mode
# Run arbitrary C# — e.g. add a GameObject named "Joe" — when the Editor exposes eval:
unity command eval 'new UnityEngine.GameObject("Joe");'

Requires the project's com.unity.pipeline package (Unity 6.0+) — add it once with unity pipeline install. Full details — launching a headless Editor to drive, unity list tool discovery, and authoring custom [CliCommand] tools — are in integration-advanced.md.

Step 1: Install the CLI (if not already installed)

First check if the CLI is available:
