Expect and variables
I'm trying to make an expect function that will pass through a variable.

Code:
/usr/bin/expect<<EOD
spawn su -
expect "Password: "
send "$psswd\r"
expect "#"
send "/etc/init.d/network restart >>$log\r"
expect "#"
send "exit\r"
EOD

The $log passes through but my $psswd fails

I know the password gets set to what I need it to be but it still fails when I try to execute it.

Not sure what I'm doing wrong. I have a feeling it's a syntax error... it's allways a syntax error...

Is it possible psswd contains a special character (quote backslash dollar)?
