Thread: calling perl program within a cgi script with parameters from html form

This isn't really the right email list for this question.  Try this
list instead (to which I have moved the discussion).
beginners-cgi@perl.org

However, this likely has to do with privileges to execute your perl
script.  In the last couple of days, the beginners-cgi list has
answered your question at least twice.  Remember, the webserver
(typically) runs a different user than you, so it may not have the
rights to execute the script.  Also, calling a perl program from a perl
CGI script is probably NOT the best way to accomplish the task you are
trying to accomplish.  You should probably read up a bit on database
access from CGI scripts and try an example or two.

An error message from your logs would have been helpful; otherwise its just
guessing.  In fact, if you had bothered to read your log files, you likely
could have figured it out yourself.  As long as I bother to reply, I might
as well guess at an answer.  My guess is that test.pl is not found in the
"current directory" when your cgi is executed from within webserver.  Try
specifying full path.
