I'd like to know where, if anywhere, this maps to the physical disk.
Basically, before I run a script, I want to know that the machine I

this should work:

# run mail script here

Yes, but that floods console.log with either errors "ping: cannot
resolve cerebus.local: Unknown Host" or with the 5 line output of ping.
Even with -q, the output of ping is 4 lines, not much better.
I suppose I can redirect standard output to /dev/null, then it will
only be the errors that get written to Console. However, I doubt I can
redirect both standard out and standard error and still have it work.
Hmm. Interesting,
if ping -o cerebus.local > /dev/null 2>&1 ; then
Seems to work.
