While it's possible in shells to use `exec` to reopen descriptors, Perl's exec is a different beast. You'll either replace your running program with a very short lived shell, or you'll spawn a child shell which won't affect the parent process' file descriptors in any way.	[reply]

Maybe I get it wrong, but it seems to me that tamaguchi asked how to create files, not open.	[reply]

The example he gave was using shell redirection to capture the output of his script. And even so, it's overkill to spawn another shell when a simple `{ open( my $fh, ">", $newfile ) or die "open $newfile: $!\n" }` would suffice.	[reply] [d/l]

Huh?!? Low and behold I'd just point him to my %fh; open $fh{$_}, '>', $_ or die "Can't open `$_': $!\n" for @many_files; # if they're not TOO many ;-) [download]	[reply] [d/l]
