Mercurial hg revert to undo commit

To undo a commit in Mercurial, use the strip command.

$ hg strip
hg: unknown command 'strip'
'strip' is provided by the following extension:

    mq            manage a stack of patches

use "hg help extensions" for information on enabling extensions

Fix by enabling the mq extension. Edit the hgrc in the root directory of the repository. The hgrc file is located .hg/hgrc

$ cat .hg/hgrc
[paths]
default=ssh://hg@bitbucket.org/username/myproject

$ cat .hg/hgrc
[paths]
default=ssh://hg@bitbucket.org/username/myproject
[extensions]
hgext.mq =

Then remove the commit using `hg strip'.

$ hg strip <hash_id>
