Lesson 1 - Jeremy says "something wierd"

In the first lesson at https://www.youtube.com/watch?v=Th_ckFbc6bI&feature=youtu.be&t=54m48s

about having 11501 images instead of 11500 in data/dogscats/train/dogs

this is because Jeremy used
ls -l | wc -l
the -l argument with ls
shows an extra line with total number of bytes used to store the files which was counted by wc -l as an extra line

most probably not very important but just in case anyone is wondering
