how to revert to a old commit code example

Example 1: how to revert back to previous commit in git

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts, if you've modified things which were
# changed since the commit you reset to.

Example 2: git command change to previous comit

git revert --no-commit 0766c053..HEAD
git commit


If you really do want to have individual commits 
(instead of reverting everything with one big commit), 
then you can pass --no-edit instead of --no-commit, 
so that you don't have to edit a commit 
message for each reversion. – user456814
