This cookbook will install Expect package.

Expect is a tool for automating interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip, etc. Expect really makes this stuff trivial. Expect is also useful for testing these same applications. And by adding Tk, you can also wrap interactive applications in X11 GUIs. Expect can make easy all sorts of tasks that are prohibitively difficult with anything else. You will find that Expect is an absolutely invaluable tool - using it, you will be able to automate tasks that you've never even thought of before - and you'll be able to do this automation quickly and easily.

Expect requires Tcl (tool command language). This cookbook will provide Tcl package if necessary (currently only Windows platform requires it).

• Ubuntu
• CentOS
• RedHat
• Fedora
• Mac OS X
• Windows

• Chef 12 or later

Installs Expect package on node and if the node platform is Windows then the recipe also installs Cygwin component.

Just include expect in your node's run_list:

{
  "name":"my_node",
  "run_list": [
    "recipe[expect]"
  ]
}

This cookbook provides a script provider called expect_script which will execute expect script using Tcl according to current OS.

expect_script 'Example expect script with system command' do
  code <<-EOH
    spawn ftp
    set timeout 30
    expect {
      -regexp "ftp.*" {
        exp_send "bye\r"
        exp_continue
      }
      eof
    }
  EOH
end

expect_script 'Example expect script with bash script' do
  cwd '/'
  environment 'PATH' => "#{ENV['PATH']}:/tmp/test"
  code <<-EOH
    spawn test.sh
    set timeout 30
    expect {
      -regexp "Would you like to delete your all files (yes/no)?.*" {
        exp_send "no\r"
        exp_continue
      }
      eof
    }
  EOH
  user 'root'
  group 'root'
end
