file.
The mattrib command sets the attribute options of a DOS
file using the plus (+) operator, or clears attribute
options using the minus (-) operator. DOS pathnames that
contain the '/' or '\' separator are supported. If you
use the '\' separator or wildcards, you must enclose file
names in quotes to protect them from the shell.
