Fadest (./8) :
Zip -r dossier archive
Devrait compresser dossier en archive.zip normalement.

C'est également ce que je comprends en lisant ça :

To zip up an entire directory, the command:

zip -r foo foo

creates the archive foo.zip, containing all the files and
directories in the directory foo that is contained within
the current directory.

You may want to make a zip archive that contains the files
in foo, without recording the directory name, foo. You can
use the -j option to leave off the paths, as in:

zip -j foo foo/*
