I am connecting to a device using telnet, I want my script to perform certain commands : ie- show device , show inventory..etc and write the output it sees from the terminal to a file.
this is what I have got :
#!/usr/bin/expect --
set running 1
spawn telnet <ip address>
expect {'^]'.}
expect "login:"
send "admin\r"
expect "Password:"
send "********\r"
set fh [open master1.txt w]
set fh1 [open master2.txt w]
expect "master>"
send "show device\r"
while $running {
expect {
"\n" { puts $fh "$expect_out(buffer)"}
eof {set running 0}
timeout {set running 0}
}
}
close $fh
puts done
expect "master>"
send "show status\r"
while $running {
expect {
"\n" { puts $fh1 "$expect_out(buffer)"}
eof {set running 0}
timeout {set running 0}
}
}
close $fh1
puts done
expect -re {# $}
exit
So what is happening now is after the first loop it is printing the data of the result to master1.txt file...but after the execution it comes to:
master>
and stops.. I tried modifying the second loop to say:
expect "master>" send "exit\r"
just to see if it exits out but its not reading the command and not exiting, I have to manually exit out. Please help me on what I am doing wrong. This is my first time with "expect" so "expect-ing" to learn here 
Thanks..
