Write the umask setting into the user's .bashrc file in the home directory:
bash
Copy code
echo 'umask 222' >> .bashrc
source .bashrc
Command explanation:
umask is used to control the default permissions for files and directories created by a user.
In umask:
The first digit is for special permissions and is usually 0 (can be omitted if not needed).
The second digit controls owner permissions.
The third digit controls group permissions.
The fourth digit controls permissions for others.
