+#### Sudo
+
+Although I try to avoid using `sudo`, in some cases it is quite handy. Examples can be seen on the Nextcloud page, where commands **need** to be executed as `www-data`.  
+Following a [post on lemmy](https://programming.dev/post/569497), I learned of a cool way to do this with just `su`
+
+This example copies a file in the web directory, using the user `www-data`. Command blocks using this style should be prefixed with `#` using `[shroot]`
+
+````
+[shroot]
+
+```
+su -s /bin/sh -c 'cp /var/www/html/html1 /var/www/html/html2' www-data
+```
+
+[/shroot]
+````
