+unset [ -fmv ] name ...
+ Each named parameter is unset. Local parameters remain local
+ even if unset; they appear unset within scope, but the previous
+ value will still reappear when the scope ends.
+
+ Individual elements of associative array parameters may be unset
+ by using subscript syntax on name, which should be quoted (or
+ the entire command prefixed with noglob) to protect the sub-
+ script from filename generation.
+
+ If the -m flag is specified the arguments are taken as patterns
+ (should be quoted) and all parameters with matching names are
+ unset. Note that this cannot be used when unsetting associative
+ array elements, as the subscript will be treated as part of the
+ pattern.
+
+ The -v flag specifies that name refers to parameters. This is
+ the default behaviour.
+
+ unset -f is equivalent to unfunction.
