"After a recent O/S version upgrade (to openSUSE 11.2) I noticed
that bash started being a bit more intelligent when I did something
stupid: it started giving me a useful error message when I typed
the name of a command that wasn't in my PATH but that was in an
"sbin" directory. My reaction at the time was "huh, that's nice",
but today I decided I needed a bit more information.
As an example of this behavior, if I type ifconfig while not
logged in as root I get the get the following:
Absolute path to 'ifconfig' is '/sbin/ifconfig'
