Where should I put my CGI scripts on Linux plans?

You should upload your CGI scripts to cgi-bin folder that is located under htdocs.

Files that are located in cgi-bin folder are recognized by web-server as CGI programs and run from the shell. To make CGI scripts run at your account you should do the following:

1. Set the path to interpreter at your script at the first line (i.e. #!/usr/bin/perl for Perl scripts).
2. Upload your script to cgi-bin folder.
3. Set execution mode to your script. (you can do this from "Web/FTP Server > Apache Server > Permissions" page of your HostPilot or via ftp by using "quote site chmod 755 filename" command).
4. Run it via web browser (http://yourdomain/cgi-bin/filename). You will need to put a link to the script into a web page and, possibly, create form that will submit all necessary information to the script.
