Just capture it and reuse:
password = nil
confirmation = nil
run "passwd", :pty => true do |ch, stream, data|
if data =~ /Enter new UNIX password:/
password ||= Capistrano::CLI.password_prompt(
"New root password: ")
ch.send_data(password + "\n")
elsif data =~ /Retype new UNIX password:/
confirmation ||= Capistrano::CLI.password_prompt(
"Retype new root password: ")
ch.send_data(confirmation + "\n")
else
Capistrano::Configuration.default_io_proc.call(ch, stream, data)
end
end
I'll leave as an exercise for the reader how to handle the case where
the password and the confirmation do not match, and passwd tries to
reprompt.
