Hi frnds,
This is my first post.....
I want to take IP address, username and password as command line arguments to a expect script to telnet. My script is :
__________________________________________________ ____________________
##file name is : script.sh
#!/bin/bash
#!/usr/bin/expect -- ##/usr/bin/expect is the directory where expect was installed

log_user 0 ##this command is used to hide the conversationn between the script and the other machine
set address [lrange $argv 0 0] ##assign the first passed parameter while calling the script to $address
set username [lrange $argv 1 1] ##assign the 2nd passed parameter while calling the script to $username
set password [lrange $argv 2 2] ##assign the 3rd passed parameter while calling the script to $password
spawn telnet ${address} ##start the telnet session to machine with IP=$address

##start conversation with the machine:
expect "login:"
send -- "$username\r"
expect "Password:"
send -- "$password\r"
expect "$ "
send --"exit\r"
__________________________________________________ ____________________
im running script as:
expect script.sh 10.1.101.80 root password

but it is showing the error :
can't read "address": no such variable
while executing
"set address [lrange $argv 0 0]
(file "script.sh" line 6)
__________________________________________________ ____________________

I removed #!/bin/bash but still showing same error

# works as a comment only if it's the first character on the line, so basically your comments are messing you script.Move each and every one of them to their own line and it should work(or at least spit a different error).

Thanks for your help fcojocaru ...its working now.
I hv one more issue:
I want to store the logs for some commands which i am executing in expect script, to a txt file. I want to check whether the command was wuccessful or it was failed. Log file format:
command <3> - successful
command <8> - failed
...................................
command <27> - failed


How to do this ...plz help.

This is trickier; Check the manpage of expect to see how to make a simple decision structure ( if - then - else ) , and check specifically for the log_file directive. There is no simple way to check the $? like in bash , but rather check the output of the executed command ( telnet in your case ).
