NAME    [Toc]    [Back]

     unset - Delete variables

SYNOPSIS    [Toc]    [Back]

     unset name	?name name ...?

DESCRIPTION    [Toc]    [Back]

     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.
