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