Data how to run shell script inside expect script?

I have the code like this :

Code:
shell script continues ...
....
          expect -c"
          spawn telnet $ip
          expect "login:"
          send \"$usrname\r\"
          expect "Password:"
          send \"$passwd\r\"
          expect "*\>"
          send \"$cmdstr\r\"
          expect "*\>"
          send \"exit\r\"
          expect eof"
....  
shell script continues...

$cmdstr is the command i want to execute on the remote device.
There are several cmds to execute on the remote device,but i have to telnet several times to the device to execute them.
If I can write some shell script inside expect script,then ,it loop to execute each cmd after login in,so it will telnet only once each device to execute all the cmds on it.

Anyone can tell me how to write shell scripts inside expect scripts?
Or,if you get some other methods to telnet only once to execute all cmds.Pls tell me.

Thanks.Smilie

BB-SERVICES(5)							File Formats Manual						    BB-SERVICES(5)

NAME
bb-services - Configuration of TCP network services SYNOPSIS
$BBHOME/etc/bb-services DESCRIPTION
bb-services contains definitions of how bbtest-net(1) should test a TCP-based network service (i.e. all common network services except HTTP and DNS). For each service, a simple dialogue can be defined to check that the service is functioning normally, and optional flags deter- mine if the service has e.g. a banner or requires SSL- or telnet-style handshaking to be tested. FILE FORMAT
bb-services is a text file. A simple service definition for the SMTP service would be this: [smtp] send "mail quit " expect "220" options banner This defines a service called "smtp". When the connection is first established, bbtest-net will send the string "mail quit " to the service. It will then expect a response beginning with "220". Any data returned by the service (a so-called "banner") will be recorded and included in the status message. The full set of commands available for the bb-services file are: [NAME] Define the name of the TCP service, which will also be the column-name in the resulting display on the test status. If multiple tests share a common definition (e.g. ssh, ssh1 and ssh2 are tested identically), you may list these in a single "[ssh|ssh1|ssh2]" definition, separating each service-name with a pipe-sign. send STRING expect STRING Defines the strings to send to the service after a connection is established, and the response that is expected. Either of these may be omitted, in which case bbtest-net(1) will simply not send any data, or match a response against anything. The send- and expect-strings use standard escaping for non-printable characters. " " represents a carriage-return (ASCII 13), " " represents a line-feed (ASCII 10), " " represents a TAB (ASCII 8). Binary data is input as "xNN" with NN being the hexadecimal value of the byte. port NUMBER Define the default TCP port-number for this service. If no portnumber is defined, bbtest-net(1) will attempt to lookup the portnum- ber in the standard /etc/services file. options option1[,option2][,option3] Defines test options. The possible options are banner - include received data in the status message ssl - service uses SSL so perform an SSL handshake telnet - service is telnet, so exchange telnet options FILES
