I have seen [interesting posts][1] explaining subtleties about `git reset`.

Unfortunately, the more I read about it, the more it appears that I don&#39;t understand it fully. I come from a SVN background and Git is a whole new paradigm. I got mercurial easily, but Git is much more technical.

I think `git reset` is close to `hg revert`, but it seems there are differences.

So what exactly does `git reset` do? Please include detailed explanations about:

- the options `--hard`, `--soft` and `--merge`;
- the strange notation you use with `HEAD` such as `HEAD^` and `HEAD~1`;
- concrete use cases and work flows;
- consequences on the working copy, the `HEAD` and your global stress level.

In plain English, what does &quot;git reset&quot; do?

I have a form with a standard reset button coded thusly:

    &lt;input type=&quot;reset&quot; class=&quot;button standard&quot; value=&quot;Clear&quot; /&gt;

Trouble is, said form is of the multi-stage sort, so if a user fills out a stage &amp; then returns later, the &#39;remembered&#39; values for the various fields won&#39;t reset when the Clear button is clicked.

I&#39;m thinking that attaching a jQuery function to loop over all the fields and clear them &#39;manually&#39; would do the trick. I&#39;m already using jQuery within the form, but am only just getting up to speed &amp; so am not sure how to go about this, other than individually referencing each field by ID, which doesn&#39;t seem very efficient.

TIA for any help.

Resetting a multi-stage form with jQuery

I had working code that could reset my form when I click on a reset button. However after my code is getting longer, I realize that it doesn&#39;t work anymore. 

```html
&lt;div id=&quot;labels&quot;&gt;
  &lt;table class=&quot;config&quot;&gt;
    &lt;thead&gt;
      &lt;tr&gt;
        &lt;th colspan=&quot;4&quot;; style= &quot;padding-bottom: 20px; color:#6666FF; text-align:left; font-size: 1.5em&quot;&gt;Control Buttons Configuration&lt;/th&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
        &lt;th&gt;Index&lt;/th&gt;
        &lt;th&gt;Switch&lt;/th&gt;
        &lt;th&gt;Response Number&lt;/th&gt;
        &lt;th&gt;Description&lt;/th&gt;
      &lt;/tr&gt;
    &lt;/thead&gt;
    &lt;tbody&gt;            
      &lt;form id=&quot;configform&quot; name= &quot;input&quot; action=&quot;#&quot; method=&quot;get&quot;&gt;
        &lt;tr&gt;
          &lt;td style=&quot;text-align: center&quot;&gt;1&lt;/td&gt;
          &lt;td&gt;&lt;img src= &quot;static/switch.png&quot; height=&quot;100px&quot; width=&quot;108px&quot;&gt;&lt;/td&gt;
          &lt;td id=&quot;small&quot;&gt;&lt;input style=&quot;background: white; color: black;&quot; type=&quot;text&quot; value=&quot;&quot; id=&quot;number_one&quot;&gt;&lt;/td&gt;
          &lt;td&gt;&lt;input style=&quot;background: white; color: black;&quot; type=&quot;text&quot;  id=&quot;label_one&quot;&gt;&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
          &lt;td style=&quot;text-align: center&quot;&gt;2&lt;/td&gt;
          &lt;td&gt;&lt;img src= &quot;static/switch.png&quot; height=&quot;100px&quot; width=&quot;108px&quot;&gt;&lt;/td&gt;
          &lt;td id=&quot;small&quot;&gt;&lt;input style=&quot;background: white; color: black;&quot; type=&quot;text&quot; id = &quot;number_two&quot; value=&quot;&quot;&gt;&lt;/td&gt;
          &lt;td&gt;&lt;input style=&quot;background: white; color: black;&quot; type=&quot;text&quot;  id = &quot;label_two&quot;&gt;&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
          &lt;td style=&quot;text-align: center&quot;&gt;3&lt;/td&gt;
          &lt;td&gt;&lt;img src= &quot;static/switch.png&quot; height=&quot;100px&quot; width=&quot;108px&quot;&gt;&lt;/td&gt;
          &lt;td id=&quot;small&quot;&gt;&lt;input style=&quot;background: white; color: black;&quot; type=&quot;text&quot; id=&quot;number_three&quot; value=&quot;&quot;&gt;&lt;/td&gt;
          &lt;td&gt;&lt;input style=&quot;background: white; color: black;&quot; type=&quot;text&quot; id=&quot;label_three&quot;&gt;&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
          &lt;td style=&quot;text-align: center&quot;&gt;4&lt;/td&gt;
          &lt;td&gt;&lt;img src= &quot;static/switch.png&quot; height=&quot;100px&quot; width=&quot;108px&quot;&gt;&lt;/td&gt;
          &lt;td id=&quot;small&quot;&gt;&lt;input style=&quot;background: white; color: black;&quot; type=&quot;text&quot; id=&quot;number_four&quot; value=&quot;&quot;&gt;&lt;/td&gt;
          &lt;td&gt;&lt;input style=&quot;background: white; color: black;&quot; type=&quot;text&quot; id=&quot;label_three&quot;&gt;&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
          &lt;td&gt;&lt;/td&gt;
          &lt;td&gt;&lt;input type=&quot;submit&quot; id=&quot;configsubmit&quot; value=&quot;Submit&quot;&gt;&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
          &lt;td&gt;&lt;input type=&quot;reset&quot; id=&quot;configreset&quot; value=&quot;Reset&quot;&gt;&lt;/td&gt;
        &lt;/tr&gt;
                  
      &lt;/form&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;
            
&lt;/div&gt;
```

And my jQuery:
```js
$(&#39;#configreset&#39;).click(function(){
    $(&#39;#configform&#39;)[0].reset();
});
```
Is there some source that I should include in my codes in order for the `.reset()` method to work? Previously I was using:
```html
&lt;script src=&quot;static/jquery.min.js&quot;&gt;&lt;/script&gt;
&lt;script src=&quot;static/jquery.mobile-1.2.0.min.js&quot;&gt;&lt;/script&gt;
```
and the `.reset()` method was working. 

Currently I&#39;m using
```html
&lt;script src=&quot;static/jquery-1.9.1.min.js&quot;&gt;&lt;/script&gt;      
&lt;script src=&quot;static/jquery-migrate-1.1.1.min.js&quot;&gt;&lt;/script&gt;
&lt;script src=&quot;static/jquery.mobile-1.3.1.min.js&quot;&gt;&lt;/script&gt;
```

Could it possibly be one of the reason?

&gt; **UPDATE&#178;**: With Git 2.23 (August 2019), there&#39;s a new command `git restore` that does this, see the [accepted answer](https://stackoverflow.com/a/15404733/946850).

&gt; **UPDATE**: This will work more intuitively as of Git 1.8.3, see [my own answer](https://stackoverflow.com/a/16589534/946850).

Imagine the following use case: I want to get rid of all changes in a specific subdirectory of my Git working tree, leaving all other subdirectories intact.

- I can do `git checkout .` , but [git checkout . adds directories excluded by sparse checkout](https://stackoverflow.com/questions/15251638/git-checkout-adds-directories-excluded-by-sparse-checkout)

- There is `git reset --hard`, but it won&#39;t let me do it for a subdirectory: 

        &gt; git reset --hard .
        fatal: Cannot do hard reset with paths.

  Again: https://stackoverflow.com/questions/11200839/why-git-cant-do-hard-soft-resets-by-path

- I can reverse-patch the current state using `git diff subdir | patch -p1 -R`, but this is a rather weird way of doing this.

What is the proper Git command for this operation?

The script below illustrates the problem. Insert the proper command below the `How to make files` comment -- the current command will restore the file `a/c/ac` which is supposed to be excluded by the sparse checkout. Note that I *do not* want to explicitly restore `a/a` and `a/b`, I only &quot;know&quot; `a` and want to restore everything below. **EDIT**: And I also don&#39;t &quot;know&quot; `b`, or which other directories reside on the same level as `a`.

    #!/bin/sh

    rm -rf repo; git init repo; cd repo
    for f in a b; do
      for g in a b c; do
        mkdir -p $f/$g
        touch $f/$g/$f$g
        git add $f/$g
        git commit -m &quot;added $f/$g&quot;
      done
    done
    git config core.sparsecheckout true
    echo a/a &gt; .git/info/sparse-checkout
    echo a/b &gt;&gt; .git/info/sparse-checkout
    echo b/a &gt;&gt; .git/info/sparse-checkout
    git read-tree -m -u HEAD
    echo &quot;After read-tree:&quot;
    find * -type f

    rm a/a/aa
    rm a/b/ab
    echo &gt;&gt; b/a/ba
    echo &quot;After modifying:&quot;
    find * -type f
    git status

    # How to make files a/* reappear without changing b and without recreating a/c?
    git checkout -- a

    echo &quot;After checkout:&quot;
    git status
    find * -type f

Following this Django by Example tutotrial here: http://lightbird.net/dbe/todo_list.html

The tutorial says:

&gt; &quot;This changes our table layout and we’ll have to ask Django to reset
&gt; and recreate tables:
&gt; 
&gt; `manage.py reset todo; manage.py syncdb`&quot;

though, when I run `manage.py reset todo`, I get the error:

    $ python manage.py reset todo                                       
    - Unknown command: &#39;reset&#39;

Is this because I am using sqlite3 and not postgresql?

**Can somebody tell me what the command is to reset the database?**

The command: `python manage.py sqlclear todo` returns the error:

    $ python manage.py sqlclear todo    
    CommandError: App with label todo could not be found.    
    Are you sure your INSTALLED_APPS setting is correct?

So I added &#39;todo&#39; to my INSTALLED_APPS in settings.py, and ran `python manage.py sqlclear todo` again, resulting in this error:

    $ python manage.py sqlclear todo                                      
    - NameError: name &#39;admin&#39; is not defined

Taking into consideration that there are several git commands that make no sense in a bare repository (because bare repositories don&#39;t use indexes and do not have a working directory), 

    git reset --hard HEAD^ 

is not a solution to uncommit the last change in such a repository.

Searching through the Internet, all I could find related to the topic is [this][1], in which I am presented three ways of doing this:  
1. &quot;update the ref manually (which involves plumbing)&quot;;  
2. &quot;`git push -f` from a non-bare repository&quot;;  
3. &quot;`git branch -f this $that`&quot;.

  [1]: http://kerneltrap.org/mailarchive/git/2007/7/14/251529

Which solution do yo think is more appropriate or what other ways are there to do this? Unfortunately, the documentation I found about git bare repositories is fairly poor.

Is there a way to reset the primary key of a PostgreSQL table to start at 1 again on a populated table?

Consider this scenario:

 1. Developer A does a commit: **#n**
 2. Dev. B does commit **#n+1**
 3. Dev. A does commit **#n+2**
 4. and commit **#n+3**

and then discovers that in his commit #n+2 he introduced a defect.

How can dev. A rollback his last 2 commits and continue developing on commit **#n+1**?

Tried `git reset --hard HEAD~2`[*][1], but it&#39;s coming back to dev A&#39;s commit **#n**.

I have a question about C++11 best practices.  When clearing a shared_ptr, should I use the `reset()` function with no parameter, or should I set the `shared_ptr` to `nullptr`?  For example:

    std::shared_ptr&lt;std::string&gt; foo(new std::string(&quot;foo&quot;));
    foo.reset();
    foo = nullptr;

**Is there any real difference, or are there advantages/disadvantages to either approach?**

I have a newbie question about Git:

I need to move back and forth in a history of a branch.
That means, I need to get all the files to the state they were in in some old revision, and then I need to get back to the latest state in the repository. I don&#39;t need to commit.

 With SVN, it would be

    svn up -r800

to get to revision 800, and 

    svn up

to get in sync with the repository.

I know the hash of the commit I want to get back to, so I tried

    git reset &lt;hash&gt;

which seems to get me there. But then I tried

    git pull

but that complains about conflicts.

So what&#39;s the proper way to move through the history of the branch?

I&#39;m thinking in terms of SVN, so don&#39;t hezitate to point me to some nice tutorial. Note that I&#39;ve already checked http://git.or.cz/course/svn.html and http://www.youtube.com/watch?v=8dhZ9BXQgc4 .

I have 200+ phones running stock Android that need to be wiped (in the Wipe Data/Factory Reset way) and then a new ROM installed with some additional apks.

Currently I&#39;ve got everything automated except the Wipe Data part. Everything else can be done through a .bat with a set of commands quite happily but I cannot for the life of me work out how to either imitate or force the recovery mode to wipe the data.

Things I&#39;ve currently tried:

 - Wiping the data myself using rm -r * on the folders it&#39;s supposed to do (data,cache,sd-ext etc.). This does wipe but then the ROM doesn&#39;t work properly and gets stuck in a bootloop.
 - Trying to use &quot;adb input keyevent&quot; to mimic the key presses. I have no idea what they are mapped to because they are in a UNIX shell basically and even then there is no &quot;input&quot; because the OS hasn&#39;t been loaded anyway.
 - Trying to find the file/script on the system that actually runs the wipe/reset and then running that manually. This might be the simplest way as it&#39;s already been written for me somewhere but I just cannot see where it is hidden, even in something like CWM.

If anyone has got any method whereby I could do this factory reset through a .bat or through the adb shell I would greatly appreciate it. Been trying to solve this for about 2 days now with little progress.

Wipe data/Factory reset through ADB

Take a look at this example here:

http://denise.brixwork.com/showlisting/1/8297-Valley-Drive-Alpine-Meadows-Whistler-denise-brown-real-estate

And the red tables under &quot;Specifications&quot; is not becoming the full width of the &lt;table&gt; containing it - when inspecting on Firebug, the &lt;tbody&gt; div is not 220 pixels, but rather, just over a 100 pixels based on the content width. 

    &lt;div class=&quot;grid_4 alpha&quot;&gt;
    	&lt;table width=&quot;100%&quot; class=&quot;grid_4 alpha omega&quot;&gt;
            	&lt;tr class=&quot;specrow&quot;&gt;
    			&lt;td class=&quot;specname&quot;&gt;type:&lt;/td&gt;
    			&lt;td class=&quot;specvalue&quot;&gt;House&lt;/td&gt;
    		&lt;/tr&gt;
    		&lt;tr class=&quot;specrow&quot;&gt;
    			&lt;td class=&quot;specname&quot;&gt;year:&lt;/td&gt;
    			&lt;td class=&quot;specvalue&quot;&gt;1986&lt;/td&gt;
    		&lt;/tr&gt;
    	&lt;/table&gt;
    &lt;/div&gt;

The CSS code looks like this:

    #listing_specs table {
    	width: 100%;
    }
    
    #listing_specs table tbody {
    	display: table-row-group;
    	width: 100%;
    }
    
    .specrow {
    	margin:2px 0px;
    	border-bottom:1px dotted #dadada;
    	color: #fff;
    	width: 100%;
    	background-color: #A92229;
    }
    
    .specrow:hover {
    	background-color:#fff;
    	color:#333;
    }
    
    .specname{
    	font-weight: 600;
    	padding:2px 2px 2px 5px;
    	width: 50%;
    	white-space: nowrap;
    }
    
    .specvalue {
    	font-weight:normal;
    	padding:2px 5px 2px 5px;
    	text-align:left;
    	width: 50%;
    }

I know there is a generic CSS resetter, and I think that&#39;s what&#39;s causing the problem. Unfortunately I can&#39;t go and just remove the reference to it because multiple sites refer to it from the same location at this moment, and I can&#39;t just make that change without careful review. So I need a way to override it on the stylesheet itself. The reset CSS being called is: 

    &lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;all&quot; href=&quot;http://demo.brixwork.com/master/css/reset.css&quot; /&gt;
