Capture external command output line by line on Windows 98
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 ?

Tintin, I don't your answer ?

Did you leave the word "understand" out of your answer?
What I'm suggesting is that instead of relying on an external command to get a directory listing, use the Perl method of doing it for you. That way your code is a lot more portable.
To invoke the dir command under Win98, I think you'd have to do something like "command.com dir", but that's not very portable, hence the solution I gave you.

Please let me rewrite and update my question:

There is no problem to implement it on windows 2000, but in Windows 98
you need a special shell.
The only shell that I found and it really work with is: stderr.exe*
This code is work fine on w98:
open(PROC,"stderr.exe $some_command |");
while(<PROC>) {
print ("$_");
}
close(PROC);
But the point is that it fail when I'm specify full path for "stderr.exe"
(becuase I'm exe file using perlapp and --bind don't help)
For example:
open(PROC,"C:/dir_name/std
while(<PROC>) {
print ("$_");
}
close(PROC);
My questions are:
1) why can't I specify full path ?
2) do you know any alternative shell that work on Windows 98 using pipe.

How about you include the error message to see why it is failing, ie:
open PROC,"C:/dir_name/stderr.e
open PROC,"C:/dir_name/stderr.e

Hi Tintin,
It seens the it not "die" .
There is no error and still the command is not exacuted.

Nothing has happened on this question in more than 5 weeks. It's time for cleanup!
My recommendation, which I will post in the Cleanup topic area, is to
PAQ, refund points (good progress, but ultimately unresolved).
