how to go back to previous version in git code example

Example 1: git revert commit

# Reset the index and working tree to the desired tree
# Ensure you have no uncommitted changes that you want to keep
git reset --hard 56e05fced

# Move the branch pointer back to the previous HEAD
git reset --soft HEAD@{1}

git commit -m "Reverting to the state of the project at f414f31"

Example 2: how to revert back to previous commit in git permanently

# 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 3: git go back to previous commit

git checkout 12feg3435 #commit ID

Example 4: git pull from previous commit

# This will detach your HEAD, that is, leave you with no branch checked out:
git checkout 0d1d7fc32

Example 5: git pull from previous commit

git checkout -b old-state 0d1d7fc32
