+chmod-cli
+===
+
+A simple command line tool for changing file permissions
+
+## Installation
+
+```shell
+$ npm install chmod-cli
+# Or
+$ npm install --global chmod-cli
+```
+
+## Usage
+
+```bash
+$ chmod --help
+
+  A simple Node.js module for changing file permissions.
+
+  Usage: $ chmod <path> …
+
+  Options:
+    --mode, -m    The new permissions for the file or directory.
+                  This can be a numeric mode (e.g. 666),
+                  or a string mode (e.g. 'rwxr-xr-x')
+
+  Examples:
+
+    $ chmod test.js xxx.js -m 777
+    $ chmod test.js -m 777
+    $ chmod-cli test.js -m 777
+
+```
+
+## API
+
+`chmod(path, mode, callback)`
+
+Changes the permissions of the file or directory at the specified `path`.
+
+- `path` (**string**): The path to the file or directory.
+- `mode` (**string** or **number**): The new permissions for the file or directory. This can be a numeric mode (e.g. 666), or a string mode (e.g. 'rwxr-xr-x').
+- `callback` (**function**): A callback function to call when the operation completes. The callback should take one argument, an error object, which will be null if the operation completes successfully.
+
+```javascript
+import chmod from 'chmod-cli';
+
+chmod('./test.txt', '666', (err) => {
+  if (err) throw err;
+  console.log('File permissions have been changed.');
+});
+```
