OK first of all, I am a PHP programmer but I have never done anything with CGI and don't know what it is. I know it stands for Common Gateway Interface, but I do not know what it does or what its for.
I was just told that I can upload a shell script to my cgi-bin folder and execute it.
I made a shell script myscript.sh and uploaded it to my cgi-bin folder. The first thing I noticed was my cgi-bin folder is a sibling to my root directory not a child. So I do not know how I would access it?
So I created a directory under my root called cgi-bin2 and put my script there (and chmod them to 755). Then I accessed it from my browser, and all it did was download the file.
Am I missing something?
CGI should send a Content-Type header:
#!/bin/sh
printf "Content-Type: text/plain\n\n"

Save as anything.sh (extension does not matter) in your cgi-bin folder and chmod 755.
cgi-bin does not have to be a child of your public html folder, it can be an alias.
