How to revert Git repository to a previous commit?

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
$ git reset --hard 0d1d7fc

# 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.
