Bash – viewing dll and exe file properties/attributes via the command line

bashfileslinux

I have a need to see some additional file properties for exe and dll files.

If I open windows explorer and add the additional columns to my view, I can see things like Company, Copyright, Product name and Product version when it exists for that file.

This data is available via windows explorer so it stands to reason that while the data/string may exist somewhere in the file itself I should be able to extract that information via command line in linux.

I've tried using 'strings' but have been met with limited success. Files where I know all the aforementioned data fields I cannot always see with 'strings'

I'm hoping that someone may have an alternative solution. Maybe something I haven't thought of yet, to see this information.
