A powerful and potentially dangerous tool is the ‘reset –-hard’</code> command. This git command will forcefully replace your staging area and working directory with an older version and move your current branch there.
Let's say we want to completely throw away the top two commits? All we have to do is reset our current branch to the sha of the commit you want to rewind to. In this case, the ‘beginning write support’ or our sha → ‘a6b4c974’.
git reset
$ git reset --hard a6b4c974
HEAD is now at a6b4c97 beginning write support
</pre></code>
Now whatever branch we were on (in our case, ‘master’), is now pointing at our older commit, and commits we do from that point on will move forward from there, leaving the ones we removed far behind.
