$? is a variable that holds the return code of the last system command, pipes, ..., pretty much the same as in the shell. By inspecting that you can check if your command succeded or not.
As for your 'hellow' script, your user might have the path to it in it's environment. But the user the webserver is running as (www) most probably doesn't. So it's always a good idea to use the absolute path, and ensure that the user 'www' has read & execute rights on the file. If you still have problems, add the 'holy trinity' to your script, and run it on the command line.
As for Perl spinning out of control: it might have to do with the unchecked open. I left out the success check in my examples for brevity, but you should always check the return code of it.
Hello,
I have a problem with trying to run a shell script that reads in user input, validates, and sets to a 'default' value if the input is not valid. I cannot get the portion of resetting to a default value to work. These lines are skipped, and the
value of x is still whatever the user... (1 Reply)

Web::Simple::Deployment - various deployment options
DESCRIPTION
This file documents common deployment methods for Web::Simple. If you feel one is missing, please ask in the IRC channel and we'll work
with you to add it.
CGI
The most basic deployment option is as a CGI script loading and running your Web::Simple-module:
#!/usr/bin/env perl
use Your::Web::Simple::App;
Your::Web::Simple::App->run_if_script;
Save that as script.cgi and your web server will handle it correctly.
Plack-Server
This works in with exactly the same code as CGI deployment. However instead of letting your web server load script.cgi, you run this on the
command line:
plackup script.cgi
Self-contained CGI
Sometimes your app is so small that you have only one or two tiny classes that you want to run as a CGI script. Web::Simple offers a
helpful mechanism to achieve that.
#!/usr/bin/env perl
use Web::Simple 'HelloWorld'; # enables strictures and warnings for the file
# additionally, HelloWorld is upgraded to a
# Web::Simple application
{
package HelloWorld;
sub dispatch_request {
sub (GET) {
[
200,
[ 'Content-type', 'text/plain' ],
[ 'Hello world! It is a fine ' . HelloWorld::Helper->day ]
]
},
sub () {
[ 405, [ 'Content-type', 'text/plain' ], [ 'Method not allowed' ] ]
}
}
}
{
package HelloWorld::Helper;
use DateTime;
sub day {
return DateTime->now->day_name;
}
}
HelloWorld->run_if_script;
