A cursory scan of CPAN didn't turn up a module for your specific purpose, tho I suspect that the problem is my search rather than the lack of such a module.

Nonetheless the solution is going to depend on your needs, where the .doc is when you start the process, and which version of MS Word (latest uses XML with proprietary additions).

A non-script way might be to use Open Office (swrite) to open the .doc on the Linux box, either after using a script to copy it there or after any other kind of transfer mechanism (FTP, sneaker net, SAMBA....).

More information on just what you're seeking would help.
