 <code>umask [OPTIONS] [MASK]</code>
 
 \subsection umask-description Description
 
-With no argument, the current file-creation mask is printed, if an
-argument is specified, it is the new file creation mask. The mask may
-be specified as an octal number, in which case it is interpreted as
-the rights that should be masked away, i.e. it is the inverse of the
-file permissions any new files will have.
+\c umask displays and manipulates the "umask", or file creation mode mask,
+which is used to restrict the default access to files.
 
-If a symbolic mask is specified, the actual file permission bits, and
+The umask may be expressed either as an octal number, which represents
+the rights that will be removed by default, or symbolically, which represents
+the only rights that will be granted by default.

+Access rights are explained in the manual page for the \c chmod(1) program.

+With no parameters, the current file creation mode mask is printed as
+an octal number.

+If a numeric mask is specified as a parameter, the current shell's umask
+will be set to that value, and the rights specified by that mask will be
+removed from new files and directories by default.
+
+If a symbolic mask is specified, the desired permission bits, and
 not the inverse, should be specified. A symbolic mask is a comma
 separated list of rights. Each right consists of three parts:
