When you upload a script to a web server, it is set to be only readable and writable by the owner and everyone else can only read it. Here, we will explain the process of changing the permissions of your scripts.

1). Telnet to your unix server and navigate to the directory that contains the file you wish to set permissions.
2). At the unix prompt, type chmod
3). On the same line, type a space then -v to get a message confirming permissions when executed.
4). Next, still on the same line, type oge where o is the number for owner's permission, g is the number for group permissions, and e is the number for everyone else's permissions.
5). Now, still on the same line, type the script's full name you wish to change
6). Press Enter

Note: Use 755 for scripts that need to be executed and use 644 for non-executable files.
