Expect and SFTP

[David L Brewster]

I am using sftp to transfer files to/from a remote system. That remote system is the government, so we are not exchanging ssh keys.
I am being prompted for a password each time and would think I can use "expect" to put this in my batch script. However, I am new to expect and cannot find an example on how to use this. man pages for expect didn't really help. Does anyone have an example on how to pass the password to sftp using expect?
Thanks,
Dave

HI,
never used it before but perhaps http://www.unix.com/shell-programming-scripting/21466-automating-sftp-expect.html helps you

Yes and Yes!
Both worked great.
I was unsure of syntax, but examples you sent cleared it up. Also noted some gotcha's.
Thanks to you both.

Here is what I have:

#!/usr/local/bin/expect --

set timeout 200

spawn /usr/bin/sftp -oPort=10022 username@sftp.11.22.33.gov
expect "username@sftp.11.22.33's password:"
send "password\r"
expect "sftp> "
send "lcd /tmp/ \r"
expect "sftp> "
send "get file \r"
expect "sftp> "
send "bye \r"
