Re: Does IPC::Open3 uses temporary file?

I need to read STDERR and STDOUT simultaneously

In IPC::Open3, if you set the STDERR filehandle to 0, it will be automatically combined with STDOUT.

#my $pid = open3(\*WRITE, \*READ, \*ERROR,"bc"); 
my $pid = open3(\*WRITE, \*READ,0,"bc");
            #if \*ERROR is false, STDERR is sent to STDOUT

Thanks, very interesting information... It will not help me in my case (I can't mix STDERR and STDOUT, I should differentiate those) but this could help me in a next similar problem... Now I don't remember exact details (I am home, and that Perl program at work) but I suceeded mixing STDERR and STDOUT by something like this: `open my $fhcmd, "$cmd args 2>&1 \|";` [download] Best regards, Courage, the Cowardly Dog	[reply] [d/l]

If you need to separate STDERR and STDOUT use IPC::Open3 as described in Re: Process command output after each input I'm not really a human, but I play one on earth. flash japh	[reply]
