I'm not sure exactly what you mean by "..print any data...". My web
server shows my static pages just fine. I have a test script that I
picked up somewhere along the way to test that cgi is working and that
prints data on a web page. And if I run the script from the command
line, I get this output:
blacklamb# ./uptime
Content-type: text/plain
9:56AM up 1 day, 44 mins, 1 user, load averages: 0.00, 0.00, 0.00
I'm sorry if I'm being real dense here but I have no experience with
perl and very, very little in designing web pages without the help of
(gasp) FrontPage but I'm trying to learn.
So I assume that the \n is either a CR or and LF and I need \something
else to conform to the spec? I was just using and example that was
posted previously.
Thanks for your help.
Drew
