Adding permission to web folder in Ubuntu

Permission.sh

sudo chgrp -R www-data /var/www/html/
sudo find /var/www/html/ -type d -exec chmod g+rx {}
sudo find /var/www/html/ -type d -exec chmod g+rx {} +
sudo find /var/www/html/ -type f -exec chmod g+r {} +
sudo chown -R $USER /var/www/html/
sudo find /var/www/html/ -type d -exec chmod g+s {} +

# Run these commands also, when above commands does not work
sudo usermod -a -G www-data $USER
sudo find /var/www/html/ -type d -exec chmod 775 {} \;
sudo find /var/www/html/ -type f -exec chmod 775 {} \;

You can replace $USER with your username.

After you add your username to the www-data group, logout and login to for the changes to take effects.

works fine, thanks

thanks
