Re: Capturing STDERR using IO::Handle

IPC::Open3's open3 is one way.

use IPC::Open3 qw( open3 );
use Symbol     qw( gensym );

my $pid = open3(
   my $to_chld     = gensym(),
   my $fr_chld     = gensym(),
   my $fr_chld_err = gensym(),
   'command', 'with', 'args'
);
close($to_chld);
close($fr_chld);
my @logmessages = <$fr_chld_err>;
waitpid($pid, 0);

IO::CaptureOutput is another way. `use IO::CaptureOutput qw/capture_exec/; my ($stdout, $stderr) = capture_exec( 'command', 'with', 'args' );` [download] -xdg Code written by xdg and posted on PerlMonks is public domain.
