passwd will be invoked by as the userid.
Even if you don't know anything about expect, you can pretty much figure it
out. It's real easy. It waits for passwd to print something it recognizes,
then it sends a response to that. So, you need to look at the prompts from
your passwd, and adjust the script accordingly. For example:
spawn "/usr/bin/passwd"
expect {
-re "word:" { sleep 2; send "$oldpass\n" }
eof { exit 1 }
timeout { exit 1 }
}
So the first thing expect does is wait for the string "word:" after starting
passwd, which should pick up the "Old password:" prompt from passwd. The
rest of the dialogue is similar.
