Unzip archive to an existing directory structure
When unzip finds a file that already exists in the destination, it will ask you if you want to overwrite it. You can then type y to overwrite it, A to overwrite all files, N if you don't want to overwrite any of them etc.
Example:
$ unzip archive.zipArchive: archive.zipreplace foo? [y]es, [n]o, [A]ll, [N]one, [r]ename:
