I've asked a few people and just thought about asking it here. We get sent files from an international company for design work in a zip format. Well when I run a script to unzip the files in the terminal, I receive a zip error only in Linux. We can test, unzip, browse, and modify the files with 7zip and winzip all day. When 7zip or Winzip is ran they do not indicate any security, too.

Terminal error:

compressed WinNT security missing (-7 bytes)

I've searched everywhere and find no solution or correction on this. One collegue suggested,

"using a different language version of Unzip could potentially change the Unicode required to extract the file. Think of it like a password, without the right code, you can't get in."

Why in the Ubuntu terminal will unzip display an error?

7zip works on linux too. – jordanm Dec 20 '12 at 21:30

Unicode is Unicode. It doesn't just "change" because of the locale. Your colleague is wrong. – Chris Down Dec 21 '12 at 0:10

What your colleague says has a grain of truth in it (zip doesn't specify a character set for filenames, so non-ASCII filenames can become garbled when extracted on a different system), but even that grain isn't relevant to your problem. – Ignacio Vazquez-Abrams Dec 21 '12 at 2:33

7z is the name of the command once installed. See man 7z. – jordanm Dec 21 '12 at 17:06

Can you upload one of those files somewhere? – sendmoreinfo Jan 24 at 19:14
