Anyone with an expect question?

[Steven W. Orr]

I get lucky here sometimes.

I have a script I use to su to different accounts. It has all the passwords 
and yes, for what I'm doing, it's ok. This is not a security question.

Here's the issue. From a winbloze box via putty or from a native xterm (it 
doesn't matter), I run stty -a to see the rows and columns. All is right with 
the world. If I did not use the script to su - to another account and I change 
the size of the window, the size is properly updated. BUT! If I go through the 
script and change the window size, the size is not updated.

I looked through the expect docs for interact and spawn, but I didn't see 
anything interesting.

Any expectations of wizardry? ;-)

#!/usr/bin/expect -f

set timeout -1
set user [lrange $argv 0 0]
set cmd [lrange $argv 1 end]

switch $user {
     "root" {
         set password "xxx"
     }
     "hoohaw" {
         set password "yyy"
     }
     default {
         puts stderr "No password supplied for user $user"
         exit 1
     }
}

if { [llength $cmd] == 0 } {
     spawn -noecho su - $user
} else {
     eval {spawn -noecho su - $user -c} $cmd
}
log_user 0
expect "^Password: $" {
     send "$password\r"
     expect "\r\n"
     log_user 1
}
interact
