I'm not sure I fully understand why you care about capturing the output
if you don't really need to analyze what's coming back from the command.
But you can always try some of the following.
In NT, you can usually send data to a command line in two ways,
which, to say the truth, may not work in all cases nor with all programs.
You've got to experiment a bit.
One way is to echo something and pipe it to a command, such as in
echo Y | del %TEMP%
You can redirect STDOUT if you want to, the command just doesn't
care at all :
echo Y | del %TEMP% > nul 2>&1
Another way, and this can be useful if you need to provide more that one
answer, is to redirect the content of a file to a command :
command < myfile > nul 2>&1
or
type myfile | command > nul 2>&1
where myfile contains the proper answers to the prompts that
will be emitted by 'command', one on each line, to provide the
return character.
Empty lines can play the return char. only.
I've seen cases where you needed to manually add the return
char. (ASCII 13), that not all editors can handle with grace.
In Perl, you can provide input to a process or capture output, but as
you mention, not both at once. What you might be able to do though,
is prompt the user via Perl (if you need to), then check and write the
answers to a file which you can then redirect to your command, if it
will accept that.
Not the most elegant solution, but it might work.
In fact, it might be easier to open the filehandle to write to the process
while redirecting the whole output to a file, then read the content of that
file when all is finished, if you need some kind of return information.
Give this a try and let us know.

Subject: STDIN and STDOUT
Is there a way to open a process as a filehandle that
captures
STDOUT and lets you send STDIN at the same time? I know how to do
both
separately.
I need to send data to a command at the command line that
answers
two prompts. I guess I don't really need to analyze what's coming
back
from the command but I definitely need to be able to send two pieces
of
data in answer to the two prompts. Surely there's some way.
Thanks in advance - everyone on this mailing list is so
helpful!
