local [option] name[=value]For each argument, a local variable named name is created, and assigned value.
The option can be any of the options accepted by declare.
local can only be used within a function; it makes the variable name have a visible scope restricted to that function and its children.
The return status is zero unless local is used outside a function, an invalid name is supplied, or name is a readonly variable.
&qt;local&qt;&qt; is a BASH builtin command.
