umask [-S] [mode]
umask sets the file mode creation mask of the invoking
process to the given mode. You can specify the mode in any of the
formats recognized by chmod;
see chmod for more information.
The file mode creation mask (often called the umask)
determines the default permissions for any file created by the process.
For example, a file created by the create command has
the permissions specified by the umask
unless the create command specifies explicit permissions.
Calling umask without a mode argument
displays the current umask.
-Sdisplays the umask in a symbolic form:
giving user, group and other permissions. Permissions are specified as combinations of the lettersu=perms,g=perms,o=perms
r (read), w (write)
and x (execute).0Successful completion.
