- NAME
- unset - Delete variables

- SYNOPSIS
- unset _n_a_m_e ?_n_a_m_e _n_a_m_e ...?
- _________________________________________________________________

- DESCRIPTION
- This command removes one or more variables. Each _n_a_m_e is a
- variable name, specified in any of the ways acceptable to
- the set command. If a _n_a_m_e refers to an element of an array
- then that element is removed without affecting the rest of
- the array. If a _n_a_m_e 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 vari-
- ables after the non-existent one are not deleted.
