Very Computer

      I checked most of the post to solve this problem. But, I
couldn't.

Here the script,

       Which telnets to another server and run a script and it has to
wait for that script/process to complete.

Script:

#!/usr/bin/ksh

(sleep 5; echo "<uid>"; sleep 10; echo "<passwd>"; sleep 5; echo "<run
script>"; sleep 5;
echo "wait $!"; sleep 2; echo "exit"; sleep 5) | telnet <Server Name> >
tempfile 2> /dev/null

...

Explanation:

$! will give the process ID and with that process ID we can wait until
it completes using the wait on unix machines.

I don't want to do sleep .. want to wait until the process terminates.

OUTPUT:

It's able to login and exceute the <run script> and sleep for 5 sec.
But, it's not waiting (wait $!) for the script to run or process to
complete.

Request:

How can wait until the process terminates. not sleep 10 or sleep 100
only using

 wait PID

Please, Help me to resolve this issue.

Thanks in advance,
an

You need to create a script that holds open the input file descriptor for
telnet until telnet exits.  There are various ways of doing that, but since
you're using ksh, you can simply use a coprocess and ksh will do the right
thing: wait until telnet exits, then clean up.

#!/usr/bin/ksh
telnet server-name >tempfile 2>/dev/null |&
sleep 5
print -p "<uid>"
sleep 10
print -p "<passwd>"
sleep 5
print -p "<run script>; exit"
wait

      Thanks for the suggestion.

I would like to print the output of the <run script> or what ever the
script is doing.

Just like not redirecting the output to a temp file .. Just to do it on
to screen. (like remove  >tempfile 2>/dev/null or add | tee etc)

I'm getting the following error if i do the above said.

getwinsize:ioctl: A specified file does not support the ioctl system
call.

what |& means in the 2nd line of Ur script.

Hope U understand my improper english.

Thanks,
an

  I could see that the script is waiting to run the "<run script>".

script is doing.
