NAME

       unset - Delete variables


SYNOPSIS

       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.
