Perl: Get minimum supported operating system for a binary

Question

Is there a Perl command that lets me get the minimum supported OS for any given binary?

You can manually get that information by running "link /dump /headers [binaryFile]" and looking for the "subsystem version" link. I don't want to use that since it's got really bad perf.

Thanks

Answer 1

If you need this for Windows, use get_manifest from Win32::Exe. You will need to install it first.

Answer 2

If there's a command that gets what you want, why not just run that command?

You can use backticks or qx// in Perl to get a command's output

eg:

my $output = `command arg1 arg2 ...`;

Or, if you want an array of lines:

my @lines = `command arg1 arg2 ...`;

Then you can use Perl's normal facilities for scanning that output for patterns you're interested in.

Also, your command looks like it is for Windows - is that true? If so, you should add a Windows tag.
