Re^2: Automatic generation of textfiles

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.

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]
