The original example published _inadvertently_ didn't have a pager in the pipe. To my knowledge, the hangs have all been while watching logs which don't exhibit interactive prompts (other than paging more, and more is not always involved); examples are: sudo grep -i unknown /var/log/maillog | more sudo tail -F /var/log/maillog | grep -i "yada1 yada2" rgds/ldv
