uloop execute-dynamic-code --code 'return Selection.activeGameObject?.name;'
uloop execute-dynamic-code --code 'new GameObject("MyObject");'
uloop execute-dynamic-code --code 'UnityEngine.Debug.Log("Hello from CLI!");'

PowerShell

uloop execute-dynamic-code --code 'return Selection.activeGameObject?.name;'
uloop execute-dynamic-code --code 'new GameObject(""MyObject"");'
