Vous avez cette balise avec zip et gzip, mais voici les deux. Ce sont tous deux de jolis outils Unix standard, que Mac OS X prend en charge (pour autant que je sache, en tout cas):
fichier zip :unzip -vl file.zip
Exemple:
[23:02:22] ~/Download $ unzip -vl lightbox2.04.zip
Archive: lightbox2.04.zip

Sortie ( more list_my_file.txt
):

Le drapeau -m
affiche le taux de compression:
-m list zipfile info in medium Unix ``ls -l'' format. Identical to
the -s output, except that the compression factor, expressed as
a percentage, is also listed.
