Hi: I have a script that I am executing using FileHandles in perl. My script generates STDERR, STDOUT(obviously!!!) and needs to take care of STDIN (user input from keyboard, ie it is interactive). I need STDERR (for post processing!).

I am using something like: 

open(FH, "$Exec_Cmd 2>&1 |");
while (<FH>)
{
  print $_; # I have STDERR captured in $_ but then this 
            # does not handle STDIN  
  
}

Meanwhile, If I try: 
open(FH, "$Exec_Cmd 0>&2 |");
while (<FH>)
{
  print $_; # I take care of STDIN but then this 
            # does not handle STDERR  
  
}

Can anyone please tell me how can I capture STDERR as well handle STDIN simultaneously.

Thanks and Regards, Tony
