Question

How to see the different versions of the files that we have amended after we do the commit on git.

Answer 1

I'm not very sure if looking all different versions of your committed files is possible. But you can always revert back to previous commits.

Follow the steps:

git logs

This command will give you hash value of each commit, you can use this number to perform multiple functions and reverting to an old commit is one of them. 

Command to revert back to an older commit: 

git checkout <hash_number>
