Really, forget about solving your problem with Expect and use one of the Perl SFTP modules. It doesn't matter how hard it is to get it or a new version of the script in production. Properly done, your file transfers will be reliable and you will not have to worry about them anymore. It will pay back!

My own recommendation is to go with Net::SFTP::Foreign, but I am the author, not completely unbiased!
