Unless you want to process all the data, there isn't much point in reading all the data. BTW, several times I've seen grep suck up all of memory and swap, rendering the system very sluggish, even after grep runs out of memory. Someday I'll look into it further. ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
