i have a script called "script1.sh" for auto-telnet to a cisco router
and printout the "show run" as below:

#!/bin/ksh
(
echo cisco
sleep 1
echo en
sleep 1
echo cisco
sleep 1
echo show run
sleep 5
echo exit
sleep 3
) | telnet 192.168.0.1

then I run
# ./script1.sh > script1.log
however the "show run" cannot fully display, becuase it require to
press "spacebar"

so how can i simulate "press spacebar" at the script???

thanks
steve

Try something like

echo -n " "

The -n flag tells echo not to issue a newline after the string.

Chances are that this will not work properly because of problems with
line buffering, but you can give it a try.

Something like this, details and other things probably wrong:

#!/usr/bin/expect
set timeout -1

# Some pattern that matches your prompt
set prompt "$ *"

spawn telnet 192.168.0.1

foreach cmd {cisco en cisco "show run"} {
expect $prompt
send $cmd\r
}

expect "press spacebar*"
send " "

expect $prompt
send exit\r

close
wait

No dodgy sleeping-- expect waits for the proper response and then sends
the next thing. And it can interact properly with a terminal program,
whereas your script just writes to stdin.

The programming language here is actually Tcl and if you need more help
with it, comp.lang.tcl is very good.
