Ça ne m'éclaire guère...

Merci pour vos réponses :)

J'ai posté dans le forum débutant parce-que je ne suis pas habituée aux commandes.
Je suis désolée, mais en lisant vos explications, je suis encore plus perdue...

J'ai entrée la commande proposée, le terminal renvoie des lignes et des lignes, je n'ai même pas su trouver comment faire pour afficher la suite.
