Nous commençons avec graphical.target et la première fois que la commande est exécutée, nous pouvons voir à la fois multi-user.target et graphical.target. Ceci est dû au fait que graphical.target nécessite plusieurs utilisateurs.
Ensuite, nous passons à multi -user.target. Si vous voyez multi -user.target mais que vous ne voyez pas graphical.target, nous sommes dans la cible multi-utilisateurs.
Rescue.target et emergency.target sont les deux autres cibles communes.
- Si vous voyez rescue.target, vous êtes dans la cible de sauvetage.
- Si vous voyez emergency.target, alors vous êtes dans la cible d'urgence.
