Disable console bell in FreeBSD

I use Bash and frequently utilize tab completion. On my FreeBSD box, when there are multiple options during tab completion, the annoying console bell always obnoxiously makes itself heard. For C programmers, it is the ‘\a’ that you included in your printf() calls when first learning C to drive others crazy.

To disable it, as root user you can run:

root@bsdbox# sysctl hw.syscons.bell=0
hw.syscons.bel;: 1-> 0

Add the “hw.syscons.bell=0” command to /etc/sysctl.conf to permanently disable it.  Good riddance!
