No Expect forum --- so maybe someone knows the answer

[blarneyme]

Need to run something remotely and am using
Expect which works. However, there are times
when I'm prompted differently and I'm unsure
how to get around it.

For example:
at times prompted:
(yes/no)?
Password:

other times prompted:
Password:

To account for this I've used:

expect {
	"(yes/no)?" { send "yes\r" }
	"Password:" { send "mypassword\r" }
}
set timeout -1

This works fine, except after the first password
is entered the program runs and after a few
minutes there is a second password prompt.
Adding another expect "Password:" { send "mypwd\r" }
doesn't work.

For example:

expect {
	"(yes/no)?" { send "yes\r" }
	"Password:" { send "mypassword\r" }
}
set timeout -1
expect "Password:" { send "mypassword\r" }
set timeout -1

This doesn't work and it sits waiting for the
password to be entered.

If it doesn't prompt for yes/no then this works:

expect "Password:" { send "mypassword\r" }
set timeout -1
expect "Password:" { send "mypassword\r" }
set timeout -1

How do I answer the second password prompt if
there is an initial yes/no?

Thanks!

Expect is an extension of the Tcl language, so if the below doesn't help you may have more luck in the Tcl/Tk forum.

I used something like this:

expect {
    "(yes/no)?" { send "yes\r"; exp_continue }
    "Password:" { send "mypassword\r" }
}
set timeout -1
expect "Password:" { send "mypassword\r" }
set timeout -1

The exp_continue makes it repeat the search for strings matching that first expect clause (otherwise it exits that clause), if I recall correctly.

Not the best practise I know, but I usually send a "yes" regardless, as on most *nix type platroms a "password" request comes in three times. Based on benchmarking - didn't really have any impact on the execution.
