The problem is that when the first cat completes, the reader (fgfs) gets and EoF, and that's the end of the show. ======== > It's good that you've removed the lseek from the usual path through > readline. :-) > But, as I said, your patch breaks a useful command-line option.

This has the advantage that it works the same as lseek for regular disk files, and works a whole lot better for FIFO files. It also removes the need for the "sleep" and simplifies scenario in item (1) above. ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
