Use Terminal to modify a file's metadata

[cookieme]

Hi

I have searched, but I can't find a way to simply modify certain entries of a file's metadata.

If I use mdls <filename> I can see for instance:

kMDItemAlternateNames          = (
    "test.pdf"
)
kMDItemAuthors                 = (
    "cookieme"
)

How can I change the

kMDItemAuthors  = ("cookieme")

to list "test" as author?

I have tried to do it in the application that created the pdf file, but I could not find such an option.

Thanks

Did you ever figure this out? I have the same problem.
