I am writing a shell script that unzips a ZIP file into an existing hierarchy of files, potentially overwriting some of the files.

The problem is that the unzip command asks for confirmation:
replace jsp/extension/add-aspect.jsp? [y]es, [n]o, [A]ll, [N]one, [r]ename: y

Is there an option to force unzip to overwrite the files?

According to http://www.manpagez.com/man/1/unzip/ you can use the -o option to overwrite files.

Indeed! Thanks a lot! –  Nicolas Raoul Jan 26 '10 at 10:36
e.g: unzip -o ZIP_PATH, works as a modifier. –  bonzofenix Jul 21 '14 at 22:35
