How to create templates without root in Wordpress on Linux?

Question

linux

I set up a local server on Kubuntu, it is stored in the /var/www/ folder, and there is the /html folder with Wordpress files and directories, I get to the themes folder, create my own, but every time I write sudo and run an inferior sublime, I don’t want that do. so that the files can be easily edited?
OS: Kubuntu 18.04 bionic
Kernel: x86_64 Linux 4.15.0-45-generic

Answer 1

1) Assign files to the user you are working
as 2) Add the user you are working as to the group that owns the files and
set permissions on the folder/files allowing them to be edited by the user you are working as

usermod -aG www-data <username>
chmod -R 0775 /var/www/html

!!! Before experimenting, make a backup of the /var/www/html folder to keep the current owner settings, privileges.
