what is the use of docker history command in Docker

0 votes
I am trying to find the initial docker file whom I have modified after creating the base image. I have tried different commands and I am unable to get the older docker file.

I need to compare my old and new docker file but I am unable to get the older docker file. Is there any possible way to extract it?

I am thinking of using docker history command but I don't know the use of it.

Can anyone explain me this command?
