Actually, it may not be obvious and apparent, but what you are really in need of is a closure. That is, at one point in time, you want to create a hash-value which will depend on the values which other variables have *at a later time* when you look to that value. Here's an example: 
%hash = (
   # the sub { ... } means that this is a closure (a subroutine refere
+nce)
   command1 => sub { "command_name -n $var1 -p $var2" }
);

$var1 = 'foo';
$var2 = 'bar';
# added "->()" because we are dereferencing a subroutine reference... 
+a closure
system ($hash{'command1'}->());
