Hi, I am looking for a very quick and dirty way to have my FreeBSD box page me when certain systems go down at work. The easiest way I can think of is to create a 2-way pipe between a chat command and the cu command. Something like: chat " '' ATZ OK ATDT1800PAGER# CONNECT 'PIN12345' Sent ATH" <-> cu -l /dev/cuaa0 -s 300 in a shell script or etc... Is there a shell (sh, csh, tcsh, bash) mechanism to wire process A's stdin to process B's stdout, and vice- versa, or am I going to have to use perl/expect/C (more time-consuming)? No big deal, but if anybody has a good idea, I'd appreciate it.
