You just need this command:

    hg rollback

See: http://hgbook.red-bean.com/read/finding-and-fixing-mistakes.html.

(Technically, this is deprecated as of version 2.7, August 2013, but I&#39;ve yet to see an alternative that does exactly the same thing.)

The answer is **strip** (if you don&#39;t have it enabled you can check how to enable it here: https://stackoverflow.com/a/18832892/179581).

If you want to revert just the latest commit use:

    hg strip --keep -r .
If you want to revert to a specific commit:

    hg strip --keep -r 1234

Using strip will revert the state of your files to the specified commit but you will have them as pending changes, so you can apply them together with your file to a new commit.

### Recover your stripped data:

If you miss-used the command or you want to recover your changes you can find your stripped files in the **.hg/strip-backup** folder.

In modern hg:

`hg uncommit`

or, for your exact problem:

    hg add file4
    hg amend


I would like to quickly monitor some hosts using commands like ps,dstat etc using ansible-playbook. The `ansible` command itself perfectly does what I want, for instance I&#39;d use:

    ansible -m shell -a &quot;ps -eo pcpu,user,args | sort -r -k1 | head -n5&quot;

and it nicely prints all std output for every host like this:

    localhost | success | rc=0 &gt;&gt;
    0.0 root     /sbin/init
    0.0 root     [kthreadd]
    0.0 root     [ksoftirqd/0]
    0.0 root     [migration/0]

    otherhost | success | rc=0 &gt;&gt;
    0.0 root     /sbin/init
    0.0 root     [kthreadd]
    0.0 root     [ksoftirqd/0]
    0.0 root     [migration/0] 

However this requires me to keep a bunch of shell scripts around for every task which is not very &#39;ansible&#39; so I put this in a playbook:

    ---
    -
      hosts: all
      gather_facts: no
      tasks:
        - shell: ps -eo pcpu,user,args | sort -r -k1 | head -n5

and run it with `-vv`, but the output baiscally shows the dictionary content and newlines are not printed as such so this results in an unreadable mess like this:

    changed: [localhost] =&gt; {&quot;changed&quot;: true, &quot;cmd&quot;: &quot;ps -eo pcpu,user,args | sort -r -k1 
    head -n5 &quot;, &quot;delta&quot;: &quot;0:00:00.015337&quot;, &quot;end&quot;: &quot;2013-12-13 10:57:25.680708&quot;, &quot;rc&quot;: 0,
    &quot;start&quot;: &quot;2013-12-13 10:57:25.665371&quot;, &quot;stderr&quot;: &quot;&quot;, &quot;stdout&quot;: &quot;47.3 xxx    Xvnc4 :24
    -desktop xxx:24 (xxx) -auth /home/xxx/.Xauthority -geometry 1920x1200\n
    .... 

 I also tried adding `register: var` and the a &#39;debug&#39; task to show `{{ var.stdout }}` but the result is of course the same.

Is there a way to get nicely formatted output from a command&#39;s stdout/stderr when run via a playbook? I can think of a number of possible ways (format output using sed? redirect output to file on the host then get that file back and echo it to the screen?), but with my limited knowledge of the shell/ansible it would take me a day to just try it out.

In Clojure and clojurescript you can have a private version of defn called defn-, but how do you do the same for def, as def- doesn&#39;t seem to be included?

I have a Mercurial repository that I use in local only... It&#39;s for my personal usage (so I don&#39;t &quot;push&quot; anywhere).

I made a commit with 3 files, but after that I understood that I should do commit 4 files...

Is there a way to &quot;rollback&quot; my **last** (latest, only one) commit, and &quot;recommit&quot; it with the correct files?

(I don&#39;t know why, but my &quot;*Amend current revision*&quot; option is not active, so I can&#39;t use it...)

Is there a way to see the date of a commit in github, with day/hour precision? Older commits appear in a &quot;human readable&quot; format, such as &quot;2 years ago&quot; instead of showing the actual date.

If it&#39;s not possible to see the actual date on github, is there a easier workaround than `git clone`?

I&#39;m developing a ColdFusion website using Aptana. We&#39;re using SVN for version control.

I renamed a few files and am now trying to commit one of them, but I&#39;m getting the following error:

    &#39;SVN Commit&#39; has encountered a problem.
    org.apache.subversion.javahl.ClientException: Illegal target for the requested operation
    svn: Commit failed (details follow):
    svn: Cannot commit &#39;R:\myPath\My-New-File-Name.cfm&#39; because it was moved from &#39;R:\myPath\My-Old-File-Name.cfm&#39; which is not part of the commit; both sides of the move must be committed together

This seems to indicate that I need to commit both the previous file (that was renamed) and the new renamed file together. How can I commit a file that no longer exists...?

Renamed file, now SVN not allowing me to commit?

I&#39;ve seen commit messages that refer to a specific issue / pull request.  What is the syntax to include a specific repository&#39;s issue or pull request?

I&#39;m working on a team with a few developers using git on BitBucket. We are all working on a `dev` branch, not pushing to `master` until a release.

One of the developers committed incorrect code that overwrote my own by accident, and now I am trying to push the correct code  back to the repo. I have been reading about this error for a few days now, I can&#39;t push to the repo anymore because I am getting the following error:


     ! [rejected]        master -&gt; dev (fetch first)
    error: failed to push some refs to &#39;https://myusername@bitbucket.org/repo_user/repo_name.git&#39;
    hint: Updates were rejected because the remote contains work that you do
    hint: not have locally. This is usually caused by another repository pushing
    hint: to the same ref. You may want to first integrate the remote changes
    hint: (e.g., &#39;git pull ...&#39;) before pushing again.
    hint: See the &#39;Note about fast-forwards&#39; in &#39;git push --help&#39; for details.

I follow the instructions and `pull`, but then I receive a merge conflict. After entering a message for the merge conflict, my local code is now the incorrect code that the other developer uploaded by accident (as expected from the `pull`). So I replace the incorrect code with the backup I copied before committing, and when I try to push again, I get the same error. 

It is really frustrating, I really want to help out my team and contribute, but I can&#39;t because of this error. Does anyone know how to solve this issue? I would very much appreciate any help.

These are the commands I run in order to commit if it helps anyone out:

    git pull remotename master:dev
    git add --all
    git commit -m &quot;some message&quot;
    git pull remotename master:dev
    git push remotename master:dev

I would have thought that if I kept this order, I would not receive merge conflicts. I guess I was wrong. Thanks again

Update:
I should add that I have looked for a few hours on Google and StackOverflow, and followed different instructions, but I still can&#39;t `push` to the `dev` branch.

Updates were rejected because the remote contains work that you do not have locally

I have a repository with only one branch (`master`). I&#39;m the only contributor to my repo.

I&#39;ve recently added a `tag`, both locally and pushed to GitHub. After making what I though was the last necessary commit, but now I realize I should have made one more change/commit.

So what I have is:

    commit 124
    commit 125
    commit 126 &lt;-- tag v1.0
    commit 127

and I want to move the `v1.0` tag to the next commit, ie: `127`, both locally and in GitHub.

How can I do that?

I am trying to create an ActiveRecord Object.But I&#39;m getting this error while creating it.

ActiveRecord::StatementInvalid: PG InFailedSqlTransaction

I&#39;m using EF 6.0 for my project in C# with manual migrations and updates. I have about 5 migrations on the database, but I realised that the last migration was bad and I don&#39;t want it. I know that I can rollback to a previous migration, but when I add a new (fixed) migration and run Update-Database, even the bad migration is applied.

I was trying to rollback to the previous migration and delete the file with bad migration. But then, when I try to add new migration, I get error when updating database, because the migration file is corrupted (more specifically, first line of code rename the table A to B  and is next lines, EF is trying to update table with name A - maybe it is some EF bug).

Is there some query I can run, which would tell EF something like &quot;Forget last migration like it never existed, it was bad&quot;? Something like Remove-Migration.

**Edit1**
I found solution suited for me. Changing model to the good state and run `Add-Migration TheBadMigration -Force`. This will re-scaffold the last, not applied migration.

Anyway, this still not answer the original question completely. If I UpdateDatabase to the bad migration, I did not found good way how to rollback and create new migration, excluding the bad one. 

Thanks
