```
    spawn ssh "$username@$host"
    match_max  10000000

    expect {
      timeout { send_user "\nFailed to get password prompt\n"; exit 1 }
      eof { send_user "\nSSH failure for $host\n"; exit 1 }
          "*yes/no*"
           { send -- "yes\r" }

           "*?assword:*"
    }

    send -- "[read [open "passwordfile" r]]\r"
    expect {
              timeout { send_user "\nLogin incorrect\n"; exit 1 }
              eof { send_user "\nSSH failure for $host\n"; exit 1 }

         -re  "$prompt"
           { send -- "\r" }
           }

```

This is the part of my code but the problem is sometimes i may get a yes prompt or sometimes i may not so it should be like:

```
   if { yes no prompt found } {
    send yes
    }
     else
    {
     look for  password prompt
     }

```

but the above lines does not work. this is what debug data shows
