How to change a file extension

It's sometimes necessary to change a file extension to ensure it functions as intended. For example, if you create a text file on your computer, it's saved with the extension of .txt. 

If the file needs to be a phpinfo.php, .htaccess, or phprc file, the extension must be changed or removed. This article explain how to adjust the file extension.

This article assumes you have already created or uploaded the file to your website at DreamHost. View the following articles for instructions on how to upload your file or create it on the server:

[server]$ mv phpinfo.php.txt phpinfo.php

This example shows how to remove the extension while also renaming it:

[server]$ mv php.ini phprc
