I have a simple telnet script that logs into a device and issues a number of commands with "sleep" between each command. This works great, although it would be nice to execute each command based on a response rather than an assummed sleep time?

The reponse received is "COMPLD" which could trigger the next command. Here is a similar example script with "sleep" in between each command.

Thanks.

--------------------------------------------
#!/bin/sh
host=10.1.2.2
login=admin
password=admin

command1="show software"
command2="show card software"
command3="conf t1 state up"
{
echo "$login""\r"
sleep 2
echo "$password""\r"
sleep 2
echo "$command1""\r"
sleep 2
echo "$command2""\r"
sleep 2
echo "$command3""\r"
sleep 2
echo "Y""\r"
sleep 3
echo "exit""\r"
}| telnet $host

I think you are looking for "expect" scripts. expect is a scripting language like shell or perl and you need to install it as a package.

There is nothing in a shell script that can act upon the return of a set of characters?

I will install Expect and brush-up.....
