Now, my question is this: is this the right way to retreive just 1 record,

Whenever I've had to execute system or shell commands, I use the
backtick operator, the system command, or filehandle half-pipes (or
whatever they are called :). And I've always seen these recommended
whenever someone asks how to do that.
But recently, I saw the use of the Shell.pm module:
%ignore = map { $_ = 1 } @ignore;
@diff = map { $a{$_} ne $b{$_} }
grep { !$ignore{$_} } keys %a;
@diff will end up with a list of key/value pairs of %a that are
different from %b, excluding those of %ignore.
note: this is untested.
