I'm not exactly sure this is what happened but I can't think of

from the '/usr/bin/head' command. When I ran 'head' manually the
command was not the normal one. It appears that one of the perl
packages replaced the normal 'head' command that works on files,
with one that works on URLs. Has anyone encountered this, or can
anyone determine if my surmise about one of the perl packages is
correct? Thanks.
This is a common gotcha on Os X.
No, it *was* a common gotcha, several years ago.
In the Perl distribution there is a script called "HEAD" which
indeed does fetch the header of an HTML file from the web. This
clashes with the standard Unix "head" command.
It's in the LWP module, not the core Perl distribution.
There is a standard workaround
Yes, it's called reading the instructions and paying attention. The
current default behavior for LWP when installing on a case-
insensitive is to *not* install the HEAD alias for lwp-request.
That's been the default for quite a long time now - a couple of years
at least. You have to specifically override the default for this to
happen.
