Logically that should only unset the elements of an array and not the
array variable
itself since '*' or '@' is more of a wildcard that represents the
indices. However, bash
does otherwise:
#define ALL_ELEMENT_SUB(c) ((c) == '@' || (c) == '*')
...
if (ALL_ELEMENT_SUB (sub[0]) && sub[1] == 0) // If substring is
just '@' or '*'
{
unbind_variable (var->name); // It just removes it.
return (0);
}
Bash version is 4.3.33.
