On my Linux system, I just say

perl count_moves.pl logfile

where logfile is the full (or relative) path to the logfile. You may
have to specify a full path to the perl script as well. Keep in mind
that you have to run this from the command line. It just outputs the
number of twists used to solve the puzzle after subtracting out the
original twists used to scramble the puzzle.
