I have a small `tail' program to which I would like to add the magical `-f' option. This waits while new lines are added to the file and shows them as they are being added. Now I know that while I am kermiting something, it has a zero size in the directory and you get a `file in use' type of error if you try to look at it. Is there any way to gain read access to a file that is being written to by another process? Hobie Orris | "I'm checking out of this bourgeois motel - guest of SoftQuad Inc.

Most people open the file with 1006 (to create the file). If you open a file with modes 1005 you can still write to it, and other processes can read from it (or also write to it) simultaniously. -Matt
