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?

Solution

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

This is inaccurate, umask works the other way around than chmod. Setting an umask of 777 would give nobody permission to do anything (the permissions set would be 000).
