How to change permissions for a folder and its subfolders/files in one step?

Question

I would like to change permissions of a folder and all its sub folders and files in one step (command) in Linux.

I have already tried the below command but it works

Answer 1

For already created files:

find . \( -type f -exec chmod g=r,o=r {} \; \) , \( -type d -exec chmod g=rx,o=rx {} \; \)

---

For future created files:

sudo nano /etc/profile

And set:

umask 022

Common modes are:

• 077: u=rw,g=,o=
• 007: u=rw,g=rw,o=
• 022: u=rw,g=r,o=r
• 002: u=rw,g=rw,o=r
