Except that it will essentially create a new file. Why did you want to avoid writing a new file? As far as I know, you can't just "erase" data in the middle of a file. That's just not how they work. Someone correct me if I'm wrong. As far as I know, any program that does this rewrites the file. The only thing that is somewhat similar is that you can do a sysread and change part of a file, but I don't think you can remove part of a file without rewriting it.
