After using git to get the code, the owner and group have changed. Is there any solution?

Now I use the root account to update the code. Before, the owner and group of the kernel.php file were www. Now after the update, it becomes root. Is there any way not to change it?

The easiest way is to switch to the www user and then pull the code, or use chown -R www:www . to re-update the owner after pulling the code.

Just use the aliasalias that comes with Linux to map it.

alias wwwgit='su - www -c git' 

Then use wwwgit instead of git in future commands.
