how to revert the previous commit in git 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 revert all commits to pervious commit

git revert --no-commit <commithash>..HEAD #revert changes in range of commits from head to back to that commit hash

Example 3: git go back to previous commit

git checkout 12feg3435 #commit ID

Example 4: get back some commits git

git revert {commit_id}'
