Accessing Train.csv through 'ls' python command

Important

“Since fastai-1.0.1 release in Oct 2018, fastai-v1 is now the main code base inside fastai git repo . The fastai-v0.7 code base has moved to the old/fastai directory inside the same repository. And there is a symlink that points from courses/*/fastai to ../../old/fastai so the notebooks under courses/*/*.ipynb currently still work with the v0.7 code base.”

The above is from this link “Fastai v0.7 install issues thread”.

Does that mean when we follow the instructions , it is already symbolic link to the old/fastai directory? That’s why when I access with ‘ls’, it just reach to ‘old/fastai/’ ?
Thanks !
