> Manage the read/write/execute permissions that are masked out (i.e. restricted) for newly created files by the user.
Display the current mask in octal notation:
umask
Display the current mask in symbolic (human-readable) mode:
umask -S
Change the mask symbolically to allow read permission for all users (the rest of the mask bits are unchanged):
umask {a+r}
Set the mask (using octal) to restrict no permissions for the file's owner, and restrict all permissions for everyone else:
umask {077}
