 MinusX
 ======
 
 MinusX is a utility that finds files that shouldn't have a
 [UNIX executable mode](https://en.wikipedia.org/wiki/Modes_(Unix)).
 
 Files that are marked as executable must either have a MIME type of
 `application/x-executable` or `application/x-sharedlib`, or start with
 a [shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)).
 
 It can be installed via composer:
 
 `composer require mediawiki/minus-x --dev`
 
 Usage:
 
-`minus-x.php check .`
+`minus-x check .`
 
 And to automatically fix errors:
 
-`minus-x.php fix .`
+`minus-x fix .`
 
 
 If you need to whitelist a specific file, create a `.minus-x.json` in
 the repository root:
 
 ```
 {
 	"ignore": [
 		"./bin/executable"
 	]
 }
 ```
 
 
 MinusX is licensed under the terms of the GPL, v3 or later. See COPYING
 for more details.
