Shell Programming and Scripting

I'm trying to capture the files that this command types out, but i'm not able to do it. I'm pipeing everything to the telnet command because if i dont the connection closes. Any suggestions.


#!/bin/ksh

hostn='x.x.x.xx xxxx'
(echo "open $hostn\r"
sleep 3
echo " \r"
sleep 2
(echo "dir disk1:\r"; sleep 3 ; echo "\r") | tee > /usr/autoprog/prod/rob/dump2
echo "\r"
sleep 2
grep -i c12kprp-diag-mz.RELEASE66 < /usr/autoprog/prod/rob/dump2
rcode=$?
echo "$rcode"
sleep 2
echo "dir disk1:\r"
sleep 3
grep -i "size"
rcode=$?
echo "$rcode"
sleep 2
) | telnet &
exit

Results:

If i dump the results of file dump2. I get:
% more dump2
dir disk1:
<=== Where's the output????

I've tried it without the "tee" and i still just get dir disk1:
Is there a better way of saving a couple of line after "dir disk1:" to maybe a variable to that i can compare it.
Thanks for any help

[edit] Figured it out.

The echoes and the execution of them are completely seperate, you realize. Just because you echo something doesn't mean it's executed simultaneously -- they're just words flying over a pipe, not waiting for anything. Which means the "grep -i c12kprp-diag-mz.RELEASE66 < /usr/autoprog/prod/rob/dump2" might happen before you get any results.

How about moving the pipe, redirection etc. outside of the telnet block? It'll make it a lot easier to see what's doing what at least.

Can you give me an example i'm still kinda new to this.
Thanks

Instead of (echo something | tee | grep something ) | telnet, how abut (echo something) | telnet | grep something
