powder down without password

powder_down.md

Put this in your shell startup file (.zshrc, etc). the \r is required after your password to execute the carriage return

function powder_down() {
expect <<EOF
spawn /Users/<yourname>/.rbenv/shims/powder down
expect {
  "Password:" { send "<password here>\r"; exp_continue }
  eof
}
EOF
}

Then, update any aliases to use powder_down instead of powder down:

alias pd="powder_down"
