Expect script, scp and find command

I have a script that requires a password as entry (yes, I know it is not safe to do so...), which is then entered automatically with the expect command:

#!/usr/bin/expect -f
set pass [lindex $argv 0]
spawn -noecho scp file username@server:/folder/
which works fine. However, I have no idea how to recursively copy directories, because

spawn -noecho scp -r username@server:/folder/
does not work. It gives the the options of scp. Somehow I am not allowed to pass arguments of scp to spawn, I guess.

Another thing is that I would like to copy certain files of a certain types to the server and not whole directories. Without the expect interpreter (but with bash, so the first line would read #!/bin/bash) I would do something like:

find ./ -name "*.filetype" -exec spawn scp "{}" username@server:/folder \; -print
but then I get >>invalid command name "find<<. Probably because "find" is a part of the bash interpreter and not expect. Does anyone have an easy solution to this? Or a not so easy one, but a solution that I can understand (me = advanced n00b)?

You haven't specified where you want to copy from (like "file" in your first example) - if you want to copy everything starting in the current directory you would need to do:

spawn -noecho scp -r . username@server:/folder/
But you should really investigate rsync which is ideal for the type of copying that you want to do, particularly if you want to include/exclude certain filenames. Using find to fork a separate scp process for every file would not be terribly efficient.
