Kindly let me know the way of execution CGI script

Dear Monk,
Running CGI is more than just creating HTML. You (or you system administrator) have to configure the server it is running on to deal with CGI and in the case of Perl/CGI you need to have handlers in place to deal with handing Perl off to an interpreter.

If that is all equal and good you then need to ensure that the file permissions and ownership for the CGI script are set correctly depending on what environment you are running under. Windows, Unix and Linux play by different rules so you have to understand the environment you are running in.

My advice to you is to start on the Tutorials page and look especially under CGI Programming and really read those pages and understand them. It will pay off in the long run.

I'd also recommend you read and understand this page and some of the pages referenced in there and additionally this page and especially this page just to make your life here at the Monastery a lot easier.

When you ask question please give as much complete information about what you are experiencing as you can. Log files from servers (which Corion mentioned) are one of my personal favorite ways of finding out what has gone wrong. Using [code] tags for your code as the anonymous monk mentioned is also a must.

My intent is not to give you a hard time, but it is to help you understand how to properly get the most out of this community in terms of help and knowledge possible and hopefully in the future you can pay that forward by helping someone else out down the road.

You don't show us what error message you got, what webserver you're using and if it's configured correctly. You can help us help you better by telling us these things.

The way this script is supposed to work is as follows: The first time you access the URL, it displays a form. When you submit the form, the script gets called a second time, passing along your form data and displaying it.

By capturing the output of the first run as HTML, you've created a "snapshot" of the first run's output. But when you click submit nothing happens, because the HTML is not a script.

In simple terms, a web server does one of two things:
1. if you request a file from inside the html directory, it just gives it to you. It's up to your browser to parse and render any html markup the file may contain.
2. if you request a file from inside the cgi-bin directory, the web server runs the file and delivers the output (if any) to your browser.

So, short answer: you put the output of your script in the html directory when what you need to do is put your script in the cgi-bin directory.
