UMASK:- user file creation mask. This tells which
permissions are hidden from the owner, group and other. It
doesnt tell which permissions are granted rather tells which
are denied.

Default file permissions=666
Default directory permissions=777

Actual file permissions= (Default file permissions) - (Value
of Umask)
If value of UMASK = 232 then actual file permissions=
666-232= 434

Value of UMASK can be changed by the following command:-
UMASK <new_value_to_be_given>
UMASK 253
