Could not find the file path [Docker]

[sc0rp10n-py]

I have both files placed in the root folder, it self, but running the docker gives error

sc0rp10n@sc0rp10n-pys-MacBook-Air untrunc % ls
COPYING		Dockerfile	Makefile	README.md	broken.mov	ok.mov		s		snapcraft.yaml	src		untrunc.pro
sc0rp10n@sc0rp10n-pys-MacBook-Air untrunc % docker run -v /:/mnt untrunc ./ok.mov ./broken.mov

By calling -v /:/mnt, you're telling Docker to mount the local folder / into the container at the mountpoint /mnt. You're then calling untrunc in the container with paths referring to the container's PWD.

You probably want docker run -v .:/mnt untrunc /mnt/ok.mov /mnt/broken.mov.
