John's valid concerns aside, here's the basic ide using CGI.pm. Yes it's
a module, however it has been distrubited with the Perl core for quite a
while now, so you probably have access to it.
In your CGI you will need to make a CGI object. Read the documentation,
but commonly its:
use CGI qw(:standard);
our $CGI = new CGI;
Then in the subroutine where you read the file:
my $datafile = $CGI->param('datafile');
while (<$datafile>) {
# some stuff
} # while
That's pretty much all there is to it on the server side. I've always
found the docs a little confusing on how to get the usuable filehandle,
but the above always works for me.
One other important consideration though is that the form presented to
the user must be multipart. So your form tag in your web page should
look something like:
<FORM ACTION="http://$ENV{HTTP_HOST}/cgi-bin/foo.cgi";
enctype="multipart/form-data" METHOD="post">
HTH!
