Capture external command output line by line on Windows 98

[Dib Urim]

Hello,

I'm trying to Capture external command output and error line by line.
I wrote this example witch work excellent on Windows 2000:

open(PROC,"DIR 2>&1 |");
while(<PROC>) {
print ("LINE:$_");
}
close(PROC);

But on Windows 98 it don't do nothing!
I'm user perl 5.6.1 activestate 625.
I need to display the output line by line and not all at once
so I can't use system command.
How can I implement it on windows 98 ?

Thanks
Dib

Hi Dib,

DIR is a built in to the command interperter, command.com.

You have to do this:

open(PROC, "command.com /c DIR |");

Cheers,

Hello Ben,

Thank for you quick replay.
What abut command/utils that are not in the command interpreter.
Specially I need to capture the output/error of utility called rsync.exe

For an idiomatic Perl solution, type:
perldoc -q "STDERR"

This will produce perlfaq8, which approaches the question ...
"How can I capture STDERR from an external command?"

You could also use Google, using the following keywords:
"comp.lang.perl.misc STDERR capture"

This query gives, again, idiomatic Perl solutions. For OS specific
solutions, use whatever command you execute at the command line in the
system call.

This question has been asked and answered before - so the solution is
available to you

Hi Dib,

I really don't know whether you can do this in Win98. Sorry.

I suggest you try a Windows newsgroup.
