Hi Jerry,
Thanks for your suggestion.My script worked. Now i am doing the script for `show run` for router.But i want to remove the `!` character that is getting stored in the output file. How to ignore `!` character and replace it by blank space.

Below pasted the current output what i am getting.

Current configuration : 1094 bytes
!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
!
hostname R2
!
boot-start-marker
boot-end-marker

I need output like this

Current configuration : 1094 bytes
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
hostname R2
boot-start-marker
boot-end-marker


This is my script:

#!/usr/bin/expect -f
spawn telnet localhost $argv
expect "Escape character is '^]'."
expect -re "Connected (.*)\n"
send "\r"
expect "> "
send "enable\r"
expect "Password: "
send "rout\r"
expect "# "
match_max 40000
set output [open "/root/output2.txt" "w"]
send "terminal length 0\r"
expect "# "
expect "*"
send "show run\r"
expect -re "Building configuration (.*)"
expect -indices -re ".+"
expect -re "\r\n(.*)\r(.*)(\\\$ |# )"
set outcome $expect_out(buffer)
send "\r"
puts $output $outcome


Please help me debug the script.

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
