This question already has an answer here:
There is a fundamental aspect of the way permissions work in linux directories I think I have not understood.
I have this folder I was trying to access from my local apache server :
sudo chmod 777 /home/ut/programmes/Programmation/p5-linux/ sudo -u www-data ls /home/ut/programmes/Programmation/p5-linux/ ls: cannot read directory '/home/ut/programmes/Programmation/p5-linux/': Permission denied
Why is it not working ? even though the permission is 777 ?
Moreover, by doing :
sudo chown ut:www-data /home/ut sudo chmod 710 /home/ut
without changing anything to the permission in /home/ut/programmes/Programmation/p5-linux/, now this is what I get :
sudo -u www-data ls /home/ut/programmes/Programmation/p5-linux/ icudtl.dat libffmpegsumo.so locales nw.pak p5 p5.png Projets
the only thing I did was to change the group of a parent dictory. why does it work now ?
