I have been using linux for many many years and have always dealt with .tar.gz files. I have never used zip files on linux until today when I needed to unzip some 100 odd theme files for WordPress.
A simple mistake on my part had me scratching my head.unzip *.zip gave me the error message;
Caution: filename not matched.
After a bit of head scratching and to be honest a search on google, I found the answer.
This passes the parameter to unzip unparsed.
