unset name ?name name ...?
_________________________________________________________________
DESCRIPTION
This command removes one or more variables. Each name is a
variable name, specified in any of the ways acceptable to
the set command. If a name refers to an element of an array
then that element is removed without affecting the rest of
the array. If a name consists of an array name with no
parenthesized index, then the entire array is deleted. The
unset command returns an empty string as result. An error
occurs if any of the variables doesn't exist, and any
variables after the non-existent one are not deleted.
KEYWORDS
remove, variable
