    You can do this in bash too:

    echo testing again from my home machine >> /dev/udp/

    bash can also use a (resolvable) hostname rather than an IP address. ksh93 (most commonly found on commercial unix systems as /usr/dt/bin/dtksh) seems to work only with IP addresses.

    gawk has similar syntax and functionality.
