Calling Expect Script - Telnet
Hi All,

I have an Expect script which logs into Cisco switch, performs a show interface command. I want to read a file of ip addresses which will be passed to the expect script.

The script to read the file works, the expect script works on it's own but when i call the 'expect' script from the control script it fails with : : spawn: not found

I've looked at many threads on many forums but unable to work this one out, any help would be appreciated.

Script1: Control Script:
Code:
#!/bin/bash
#!/usr/bin/expect -f
#
#
while read  ipadd
do
echo $ipadd
export ipadd
sh ./list-int $ipadd
done < dev-list

Script2 : Expect
Code:
#!/usr/bin/expect
#!/usr/bin
# Variables #
#set device "10.33.220.12"
set device $1
set user ****
set cmd1 "term len 0"
set cmd2 "show ip int brief"
set logout "exit"
set pass ****
set timeout 100

#TELNET
spawn telnet $device
expect "Username:"
send "$user\n"
expect "Password: "
send "$pass\n"
expect ">"
send "en\n"
expect "Password: "
send "$pass\n"
expect "#"
sleep 2
send "$cmd1\n"
expect "#"
end "$cmd2\n"
expect "#"
send "$logout\n"

Please remove the expect line from the control script and it will/should work.

so when you run it manually giving it an IP argument it works, right?

sh ./list-int 10.x.x.x

where list-int is your expect script.

In your control script, modify #!/bin/bash to #!/bin/bash -x, this should enable tracing. Post the output from the run with trace output. If it is a lot of output, put in a file and attach to your post.

Correct, running with manual IP argument works.
Output from run with trace :
Code:
/Scripts$ ./get-int
+ read ipadd
+ echo 10.33.220.12
10.33.220.12
+ export ipadd
+ sh ./list-int 10.33.220.12
./list-int: 17: spawn: not found
couldn't read file "Username:": no such file or directory
./list-int: 19: send: not found
couldn't read file "Password: ": no such file or directory
./list-int: 21: send: not found
couldn't read file ">": no such file or directory
./list-int: 23: send: not found
couldn't read file "Password: ": no such file or directory
./list-int: 25: send: not found
couldn't read file "#": no such file or directory
./list-int: 28: send: not found
couldn't read file "#": no such file or directory
./list-int: 30: send: not found
couldn't read file "#": no such file or directory
./list-int: 32: send: not found

and repeat for every entry in dev-list file.


Thanks again....

What is line number 17 of your expect script? it is failing on that.

Yes, that's the error I posted originally. It's the spawn telnet $device command which works when run with manual IP but fails when called from control script.
