This will be a very short post, because it’s meant primarily as a way for me to remember a git command which I seldom use, but when I do, I never remember the exact syntax.
As they say:
If you want to remember somethinng, write it down
In this case you will have to use the
reset command and will have to specify the revision you want to rewind to.
To preserve the changes, use the
--soft flag which will preserve your revisions. At this point you will be able to make any changes and re-commit them once you are done with your work.
$ git reset --soft HEAD~1
If instead you want to discard all the changes, you will have to use the
$ git reset --hard HEAD~1
HEAD~1 syntax is a short form to specify how far back we want to rewind,
~1 specifies the last revision. Of course you can do
HEAD~3 which would rewind the last 3 commits.
Or if you want to specify a specific revision you can simply to the following
$ git reset --hard 1cd9b7a3
Use with caution since you will lose the commits you have discarded.
To push the changes to your remote repo, you will have to use the
-f option to force push, this will in effect strip the remote commits, so please make sure you exercise caution when doing so.
$ git push -f
