$BUILTIN umask
$FUNCTION umask_builtin
$SHORT_DOC umask [-p] [-S] [mode]
-The user file-creation mask is set to MODE. If MODE is omitted, or if
-`-S' is supplied, the current value of the mask is printed. The `-S'
-option makes the output symbolic; otherwise an octal number is output.
-If `-p' is supplied, and MODE is omitted, the output is in a form
-that may be used as input. If MODE begins with a digit, it is
-interpreted as an octal number, otherwise it is a symbolic mode string
-like that accepted by chmod(1).
+Display or set file mode mask.
+
+Sets the user file-creation mask to MODE. If MODE is omitted, prints
+the current value of the mask.
+
+If MODE begins with a digit, it is interpreted as an octal number;
+otherwise it is a symbolic mode string like that accepted by chmod(1).
+
+Options:
+ -p if MODE is omitted, output in a form that may be reused as input
+ -S makes the output symbolic; otherwise an octal number is output
+
+Exit Status:
+Returns success unless MODE is invalid or an invalid option is given.
