Hey-
Here is a task I use to add users and set their passwords:
task :new_user, :roles => :slice do
run "adduser rcreasy"
run "passwd rcreasy" do |ch, stream, out|
ch.send_data 'xxxxxxx'+"\n" if out =~ /New UNIX password:/
ch.send_data 'xxxxxxx'+"\n" if out =~ /Retype new UNIX password:/
end
end
Cheers-
-Ezra
