How do I git reset --hard HEAD on Mercurial?
Solution 1
If you've not yet commited, and it sounds like you haven't you can undo all the merge work with hg update --clean
.
However, in newer mercurial's there's a handy command to re-merge a single file: hg resolve path/to/file.ext
. From the hg help resolve
:
The available actions are: ... 4) discard your current attempt(s) at resolving conflicts and
restart the merge from scratch: "hg resolve file..." (or "-a" for all unresolved files)
Solution 2
This is close:
hg update --clean
Solution 3
From git, commands:
git reset --hard # reset to last commit
git clean -df # delete untracked files
are equal to
hg update --clean # reset to last commit
hg purge # delete untracked files
Solution 4
The Hg Manual’s GitConcepts page explains how to do many actions git
users are familiar with in Mercurial.
Mercurial doesn’t have any built-in git reset --hard
behavior. However, the strip
extension provides a strip
command which does. To use, first enable strip
in your ~/.hgrc
file::
[extensions]
strip =
Note: this extension is shipped in new in Mercurial 2.8. Prior versions provided the strip
command in the mq
extension.
Now you can run commands like hg strip
or even hg help strip
. To remove a changeset and all of its children, simply specify that changeset as an argument to hg strip
. For example, to remove the last commit you just made (after you used commands which caused hg rollback
to report that there is no longer any transaction to rollback), you can remove the tip
revision. Each time you run this command, another revision will be removed. hg strip
’s actions should be considered irreversible; unfamiliar users should make backups of their repositories before using.
$ hg strip tip
For example, with revsets syntax, I indicate that I want to remove any commits of mine which result in extra heads being shown when I run hg heads
. If you specify a particular revision in the below expression other than tip
, everything in the current branch that is not an ancestor of your chosen revision will be trimmed. This seems closest to the behavior I want when I issue the command git reset --hard HEAD
.
$ hg strip "branch(tip) and not(ancestors(tip)::tip)"
Solution 5
What I expected to find as an alternative to git reset --hard
in mercurial was:
hg strip --keep -r . # --keep optional
hg update --clean # reset to last commit
And then if you need too:
hg purge

I'm a Git user trying to use Mercurial.
Here's what happened: I did a
hg backout
on a changeset I wanted to revert. That created a new head, so hg instructed me to merge (back to "default", I assume). After the merge, it told me I still had to commit. Then I noticed something I did wrong when resolving a conflict in the merge, and decided I wanted to have everything as before thehg backout
, that is, I want this uncommited merge to go away. On Git this uncommited stuff would be in the index and I'd just do agit reset --hard HEAD
to wipe it out but, from what I've read, the index doesn't exist on Mercurial. So how do I back out from this?-

agentofuser about 14 yearsSorry, I'm still a bit confused: I ran
hg up -C
, but the "backed out" commit is still at the tip of my branch. I thought this was a "ghost branch" that got created with thebackout
, but runninghg branch
returnsdefault
, so I'm on the main branch after all? -
Ry4an Brase about 14 yearsYou can have two heads with the same branch, and that's what you've got. They're both named
default
. This is a very normal situation in mercurial and 'hg heads
is the command you use to discover/understand it. When you ranhg backout
it "Commit the backed out changes as a new changeset" so that created a new changeset that won't go away w/o heroic effort. So now you have two heads both on the branch named default. After youhg merge
(and commit it) you'll be back to one head on the branch named default. -
davidjb about 10 yearsMercurial 2.8 and above has a
strip
extension in case one only wants thehg strip
command explicitly. Usingmq
adds a variety of other patch management commands as well. -
iLemming almost 10 yearsyeah... sometimes though when you move files around (from one directory to another) and then decide to scratch everything, it does not do the same thing as
git reset --hard
would do. Ergo - mercurial is stupid -

git reset --hard
doesn't delete untracked files. -
Hi-Angel over 6 yearsDoesn't work for me.
hg update --clean 18:8e139889ff02
says "updated 2 files", however when I look at the log, it's still where it was. UPD: that said, it did reset the files to the revision. Which is only half of thegit reset --hard
behavior though. -
Assad Ebrahim over 3 yearsIn TortoiseHg 4.7 and above, this can be enabled using File > Settings > Extensions and then check strip, and restarting TortoiseHg. Then View > ShowConsole, to get the command line to type in e.g. hg strip --keep -r 50
