The CGI extension identifies executable scripts used on web servers for dynamic output.
The standard interface CGI (Common Gateway Interface) uses scripts, usually in Perl or C, which can be precompiled to execute programs on a web server. These provide additional functions on a website, such as a form or guestbook. Dynamic advertising can also be realized in this way.
These files can only be edited if they are not compiled. But then with every text editor. Preferably, however, with a special source code editor.
Most often resolving problems with opening CGI files is very simple. Just install an appropriate program that supports such files. All of the listed programs support CGI files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of CGI files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate CGI files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the BBEdit applications is not on the list, select "Browse" option in order to manually locate the directory where BBEdit has been installed.
Sometimes problems with opening CGI files may not lie with the application itself, but can arise due to other causes, such as:
