So I want my
umask (command) which in this case is
0002 to be subtracted (bitwise) from
666 for files and
777 default base permissions for folders. For example, the result here for a file would be 664.
This is so I can change the permissions of files I created with
chmod using that new mask which is of course the default mask when you create a file with
touch for example.
How can I accomplish this?
