I suggest you take a look at perldoc -f open and your questions should be answered. Dogma is stupid.	[reply] [d/l]

If I understand you correctly, then what you're asking for is known in the Unix world as "tee". I remember having seen several solutions to solve this neatly, in Perl. In fact, it's even in the official perlfaq: How do I print to more than one file at once?	[reply]

tirwhan is right, but his link is taking forever to load, at least for me, so I'll add a little more information. Basically, you're looking for information on filehandles. You can open a file in output mode by doing something like `open MYHANDLE, '>', $filename or die $!;` and then you can write stuff to that open file with something like `print MYHANDLE $stuff;` To create multiple files, just do that repeatedly. Some wording in your question leads me to believe you already know a way to do something repeatedly. Sanity? Oh, yeah, I've got all kinds of sanity. Why, I've got so much sanity it's driving me crazy. In fact, I've developed whole new kinds of sanity.	[reply] [d/l] [select]

You can use exec or system: `exec(':> $filename');` But be careful.	[reply] [d/l]

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]

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]
