I still think it would be better to fix your PKI setup first, because
you really don't need expect in this case.

So, with a correct PKI setup, to print the filenames that start with sh in /etc,
you could simply run the following command:

Code:
$ ssh 0 'printf "%s\n" /etc/sh*'
/etc/shadow
/etc/shadow-
/etc/shells

With expect you need something like this:
Code:
$ ./s 'printf "%s\n" /etc/sh*'
/etc/shadow
/etc/shadow-
/etc/shells

This is the content of the script s:

Code:
#!/usr/bin/expect --
set Machine 0
set Username "<your_username>"
set Password "<your_password>"
set Cmd [lindex $argv 0]
log_user 0
spawn ssh "$Username@$Machine"
while 1 {
  expect {
    "\(yes/no\)\?*" {
     send "yes\r"
     continue
    }
    "assword:" {
      send "$Password\r"
      break
    }
  }
}
expect "# "
send "$Cmd\r"
expect -re "\[^\n]*\n(.*)\n.*# "
puts $expect_out(1,string)

* You'll need to adjust the expect patterns in order to match your prompt.

NAME

     mixerctl.conf -- audio mixer configuration file

SYNOPSIS

     mixerctl.conf

DESCRIPTION

     The /etc/mixerctl.conf file consists of mixerctl(1) variables to set at boot time.  Each line of mixerctl.conf has the following format:

     Set mixerctl to YES in rc.conf(5) to have the variables set at boot time.	Additionally, you can have the settings saved and restored for the
     devices of your choice by listing them in mixerctl_mixers in rc.conf(5).
