Change default permissions for new files and folders

Question

Every time I create a new file or folder in Linux, it is accessible for r/w by myself, not the group. I want to change my system setting such that every new file or folder will be automatically accessible by the group. Is there anyway?

Answer 1

From the article:

chmod g+s <directory>  //set gid 
setfacl -d -m g::rwx /<directory>  //set group to rwx default 
setfacl -d -m o::rx /<directory>   //set other

Next we can verify:

getfacl /<directory>

Output:

file: ../<directory>/
owner: <user>
group: media
flags: -s-
user::rwx
group::rwx
other::r-x
default:user::rwx
default:group::rwx
default:other::r-x

Answer 2

This can be done using the umask utility. What is Umask and How To Setup Default umask Under Linux?

You can setup a script that starts automatically on boot which executes the command

umask 777

to give everyone read/write and execute permission, for example.
