Seen Jamis posting this technique to add a prompt to a remote call, you
could tailor to your needs.
# channel: the SSH channel object used for this response
# stream: either :err or :out, for stderr or stdout responses
# output: the text that the server is sending, might be in chunks
run "apt-get update" do |channel, stream, output|
if output =~ /Are you sure?/
answer = Capistrano::CLI.ui.ask("Are you sure: ")
channel.send_data(answer + "\n")
else
# allow the default callback to be processed
Capistrano::Configuration.default_io_proc.call[channel, stream, output]
end
end
