git change head to 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 set head to commit

# Set a new HEAD to a branch
# Note that commit can be a commit hash or tag or another branch
git reset --hard $COMMIT

Example 3: git pull from previous commit

git checkout -b old-state 0d1d7fc32

Example 4: git move back one commit

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

Example 5: reset to commit

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

Example 6: reset to commit

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