NAME
       unset - Delete variables

SYNOPSIS
       unset ?-nocomplain? ?--? ?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.  If -nocomplain is specified as  the  first  argu-
       ment,  any possible errors are suppressed.  The option may
       not be abbreviated, in order to disambiguate it from  pos-
       sible  variable names.  The option -- indicates the end of
       the options, and should be used if you wish  to  remove  a
       variable  with the same name as any of the options.  If an
       error occurs, any variables after the  named  one  causing
       the  error not deleted.  An error can occur when the named
       variable doesn't exist, or the name  refers  to  an  array
       element  but  the variable is a scalar, or the name refers
       to a variable in a non-existent namespace.
