The diagnostic message you received indicates a conflict in subtroutine
prototypes.

It doesn't warn you the second time because you are not exporting the
HTML shortcuts from the CGI module, choosing instead the OO interface,
so the function ``head'' is preserved within the CGI namespace.

In reference to your original query, Theo is correct to point out the
LWP::UserAgent module for jobs such as this; you may also consider a
backtick to lynx, if you like.

For endless discussion on stuff like this, you may wish to refer queries
to Devon and Cornwall Perl Mongers:

BTW, ``which laptop?'' comes up from time to time:  I mention,
therefore, that the Compaq Evo N1015v rocks. [:-)]
