Hi,

It will affect only newly created files/processes.  The existing files/processes are not changed.

==========
$ umask
022
$ touch foo
$ ls -l foo
-rw-r--r-- 1 guest guest 0 11 10 12:36 foo
$ umask 011
$ umask
011
$ touch bar
$ ls -l foo bar
-rw-rw-rw- 1 guest guest 0 11 10 12:37 bar
-rw-r--r-- 1 guest guest 0 11 10 12:36 foo
$
==========
