Go with the simple solution, but learn to understand the other
one. There's really no need to sort the list (from an efficiency
standpoint) and the other list functions (map, grep) when all you want
is the maximum value.
You could change part of the other answer to this, though:
$index = $1 if /^$base\.(\d+)$/o and $1 > $index;
You can decide for yourself if the '/o' is appropriate in
the larger scope of the rest of your script (like not if its
a daemon that runs continuously day after day, or if it'll be
running from one day into the next day). See 'perldoc
perlop' to see what the '/o' is for if you don't know.
