Is this a valid expect statement? 1

[InigoMontoya]

while {expect "mget *.txt?"} {
      send -h "y\r"
      }

I'm trying to get all the *.txt files in remote system using the mget function of fdx file transfer utility. fdx prompts me to enter y for each file. I want to put this in a loop where whenever the server(fdx) prompts me for confirmation the loop will automatically answer y.

No, because the expect command doesn't have a return value -- or more precisely, always has an empty string return value -- and so you have an invalid boolean expression for your while command.

What you're trying to do is actually fairly easy with the exp_continue command. When used in the body of one of your expect actions when it matches a pattern, it causes the expect command to "restart;" the [tt]timeout[/tt] timer is reset and the expect command starts reading input and looking for matching patterns again. Thus, we can re-write your code as:

expect {
    "mget *.txt" {
        send -h "y\r"
        exp_continue
    }
}
