perl script/program upload small file to a very large number of newsgroups

Hi all, I'm looking for a newsgroup bulk upload perl script with which I can upload a small file (940 bytes)
to a very large number of newsgroups (serveral 1000's) that are listed in another file.
Also it has to login using username/password to newsgroup provider

Althought I already have Thunderbird, which is very conveiniant for desktop, its not up to the job
since for each newsgroup I want to upload I have to subscribe to the newsgroup and then manually
upload the small file to that group

I have search for "newsgroup bulk upload perl script" using google
https://www.google.ca/search?q=newsg...BDy0wN6BAgLEEY
but couldn't find anywhing. I also went on CPAN
https://www.cpan.org/scripts/ but nothing either

The script has to work within a shell (ex: bash, sh, csh, etc)

any ideas are welcome

thank's
