Hmm. As I said above, there's not much point in doing this, because you almost certainly won't improve performance. However, if you did want to do this you could use one of the following methods:

- print to the output file from the children instead of the parent. You'll need to lock the output file in some way (see "perldoc -q lock" for some ways on doing that) so that the writes are not completely jumbled.

- use some form of Inter Process Communication to read the file content into the parent process. Read the documentation I linked to or search cpan for IPC for various ways of doing this.

- use threads and a shared variable instead of fork.


All dogma is stupid.
