Unzip broken archive (partially)

Many solutions I found included wine and winrar (and this does not worked for me in any case btw). But I found sth different. (apt-)get (install) bsdtar!

bsdtar xf yourbrokenzip.zip

Besides for rar files the non free version does this like a charm

unrar -kb x yourrar.rar

Remember: These cmds do not repair anything. They just extract what they can!
