    git rev-parse --show-toplevel

could be enough if executed within a git repo.  
From [`git rev-parse`][1] man page:

    --show-toplevel

&gt; Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in &quot;[Is there a way to get the git root directory in one command?][2]&quot;:

    git rev-parse --git-dir

That would give the path of the `.git` directory.

---

The OP mentions:

    git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

-----

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

    git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a `.git` git-dir folder:

    git rev-parse --is-inside-git-dir

Working on a rails 3 app where I want to check if a translation exists before outputting it, and if it doesn&#39;t exist fall back to some static text. I could do something like:

    if I18n.t(&quot;some_translation.key&quot;).to_s.index(&quot;translation missing&quot;)

But I feel like there should be a better way than that. What if rails in the future changes the &quot;translation missing&quot; to &quot;translation not found&quot;. Or what if for some weird reason the text contains &quot;translation missing&quot;. Any ideas?

Rails I18n, check if translation exists?

How can I get rid of the scrollbars on a [`HorizontalScrollView`](https://developer.android.com/reference/android/widget/HorizontalScrollView.html)?

Hide Scrollbar of HorizontalScrollView

I&#39;m looking for something like `git list-path` printing the
path of the associated repository (the `.git` directory).

A bit of background: I have set up git version control on quite a few of my
projects/folders.  Some of them are nested, so one directory with echo own repository is a subfolder to another directory tracked with another repository. 

 E.g. in my home directory (`~`) I use git to track my dot files, but
in folder `~/photo/meta-mix/` I have another project I track with a
separate repository. Now, say,I have set up another project in directory
`~/photo/meta-match/`, but I don&#39;t know anymore whether it has its own
repository. So I want to find out whether this directory is version
controlled and where its repository is.

How can I do this with a git command? `git status` can give me 

    nothing to commit

in *both* cases, when `~/photo/meta-match/` has its own repository or when it just refers to the repository of `~`. 

How to find the path of the local git repository when I am possibly in a subdirectory

I'm looking for something like <code>git list-path</code> printing the
path of the associated repository (the <code>.git</code> directory).
A bit of background: I have set up git version control on quite a few of my
projects/folders. Some of them are nested, so one directory with echo own repository is a subfolder to another directory tracked with another repository.
E.g. in my home directory (<code>~</code>) I use git to track my dot files, but
in folder <code>~/photo/meta-mix/</code> I have another project I track with a
separate repository. Now, say,I have set up another project in directory
<code>~/photo/meta-match/</code>, but I don't know anymore whether it has its own
repository. So I want to find out whether this directory is version
controlled and where its repository is.
How can I do this with a git command? <code>git status</code> can give me
<pre><code class="hljs language-vbnet">nothing to commit
</code></pre>
in both cases, when <code>~/photo/meta-match/</code> has its own repository or when it just refers to the repository of <code>~</code>.

I have a large git project that I, stupidly, imported to eclipse and ran an autoformat on.  Now, every file in the project is showing as modified.  Rather than commit my formatted files, I would rather revert all the files that I have only been formatted and not had other changes.  For instance:

    $ git status
    # On branch master
    # Changes not staged for commit:
    #   (use &quot;git add &lt;file&gt;...&quot; to update what will be committed)
    #   (use &quot;git checkout -- &lt;file&gt;...&quot; to discard changes in working directory)
    #   (commit or discard the untracked or modified content in submodules)
    
    #     modified: dir/file1.cpp
    #     modified: dir/file1.h
    #     modified: dir/file2.cpp
    #     modified: dir/file2.h
    #     modified: dir/file3.cpp
    #     modified: dir/file3.h
    #     modified: dir/file4.cpp
    #     modified: dir/file4.h

I know that `file2.cpp`, `file2.h`, and `file3.cpp` have been modified with content (i.e., not just formatted).  I want to stash the changes to these three files and then checkout an old revision, so that I can reapply the changes to these files after.  I would rather avoid something like:

    $ cp file2.cpp ~/tmp
    $ git checkout blahblahblah
    $ cp ~/tmp/file2.cpp .

If there&#39;s an obvious way to do this that doesnt involve stashing, let me know.  whatever gets the job done.

Stash changes to specific files

I have been pushing to a remote Bitbucket repository and recently a colleague has pushed a new branch he created to the same repository.

I&#39;m trying to fetch the changes he uploaded.

     $ git branch -a
     * master
     localbranch1
     localbranch2
     remotes/origin/master

&gt; $ git branch -r
&gt; origin/master

In the web UI for Bitbucket I can see the branch he has made. How can I do this?

Next try:

    $ git fetch bitbucket
    Password for &#39;https://xxxxx@bitbucket.org&#39;:
    From https://bitbucket.org/user/repo
     * branch            HEAD       -&gt; FETCH_HEAD

If the branch he created is called **new_branch_b** should I be expecting to see the following?

    $ git branch -r
    origin/master
    origin/new_branch_b

Third try:

    $ git remote update
    Fetching bitbucket
    Password for &#39;https://xxxxx@bitbucket.org&#39;:
    From https://bitbucket.org/user/repo
     * branch            HEAD       -&gt; FETCH_HEAD

    $ git branch -r
      origin/master

Fourth try:

    [remote &quot;bitbucket&quot;]
    url = https://user@bitbucket.org/user/repo.git

I called the remote `bitbucket` rather than origin (at least that&#39;s what I recall; I set it up a while ago)

Fifth try:

I updated the Bitbucket remote configuration as per [kan&#39;s answer][1]:

&gt; $ git config -e

    [remote &quot;bitbucket&quot;]
        url = https://user@bitbucket.org/user/repo.git
        fetch = +refs/heads/*:refs/remotes/bitbucket/*

For most people it will be called origin:

    [remote &quot;origin&quot;]
        url = https://user@bitbucket.org/user/repo.git
        fetch = +refs/heads/*:refs/remotes/origin/*

Afterwards,

    $ git remote update

    Fetching bitbucket
    Password for &#39;https://user@bitbucket.org&#39;:
    remote: Counting objects: 48, done.
    remote: Compressing objects: 100% (32/32), done.
    remote: Total 35 (delta 21), reused 0 (delta 0)
    Unpacking objects: 100% (35/35), done.
    From https://bitbucket.org/user/repo
     * [new branch]      branch_name1 -&gt; origin/branch_name1
     * [new branch]      branch_name2    -&gt; origin/branch_name2
  .... and so on.

I think `git fetch origin` would also work for `git remote update`.

Remote branch is not showing up in &quot;git branch -r&quot;

I have a .diff file created by a coworker, and would like to apply the changes listed in that diff file to my local branch of the exact same repository.  I do not have access to that worker&#39;s pc or branch that was used to generate this diff file.

Obviously I could go line by line and retype everything, but i&#39;d rather not subject the system to human error. What&#39;s the easiest way to do this?

How do you take a git diff file, and apply it to a local branch that is a copy of the same repository?

I&#39;m trying to help out a coworker who accidentally created one feature branch from another feature branch, rather than creating the second one from master. Here is essentially what we have now…

    Master ---A---B---C
                       \
                  Foo   E---F---F---H
                                     \
                                Bar   J---K---L---M

And here is what we&#39;d like to have…

    Master ---A---B---C
                      |\
                 Foo  | E---F---F---H
                      |
                 Bar  J---K---L---M

One way I thought of would be to create FooV2 and BarV2 branches, and cherry-pick the individual commits into the appropriate V2 branches. But I&#39;m curious, is there a better way to handle this situation?

I am working on a media player in C# but when I want to make my test I have a problem.

I have to create a new object song with the following path:

    @&quot;C:\Users\Jesus Antonio\Desktop\JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3&quot;

It works but when I change the computer I have to rewrite the entire path, 
My project is called JukeboxV2.0

In java I remember you can just write the path for example

    @&quot;JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3&quot;

This will save a lot of time because I can take my project to different computers and it works, but here I don&#39;t known how to do that, anyone know?

File path for project files?

I need a valid method to check if a `String` represents a path for file or a directory. What are valid directory names in Android? As it comes out, folder names can contain `&#39;.&#39;` chars, so how does system understand whether there&#39;s a file or a folder?

Check if a path represents a file or a folder

I am trying to locate the path of the current running/debugged project programmatically in Java, I looked in Google and what I found was `System.getProperty(&quot;user.id&quot;)`, which didn&#39;t get me the project&#39;s path.

I know the command `Environment.currentDirectory` in C# gives the path of the current running/debugged project,so I am sure there must be a similar way in Java, too.

So I am asking if anyone could tell me or give me a code to how locate the path of the currently running/debugged project programmatically?

**edit**:
i am writing plugin which loads with eclipse start.
the plugin adds a button to the workbench of eclipse, with in the code of the plugin
when i click the button i search for the current directory path.

my purpose is that when for example i debug a project and then click the button, a window will pop up presenting the debugged project&#39;s path, thanks

Is there an existing function to concatenate paths?

I know it is not that difficult to implement, but still... besides taking care of trailing `/` (or `\`) I would need to take care of proper OS path format detection (i.e. whether we write `C:\dir\file` or `/dir/file`). 

As I said, I believe I know how to implement it; the question is: should I do it? Does the functionality already exist in existing R package?

Function to concatenate paths?

I&#39;d like to get the full file path, from a URI. The URI isn&#39;t a Image, but it&#39;s a music file, but if i do it like the MediaStore Solution, it won&#39;t work if the app user selects eg Astro as browser, instead of Music Player. How do I solve this?

I have some code that needs to run only if the rails app is in the development environment (i.e. $ rails server) but not in the test environment (i.e. $ rake test).

When I try

    if Rails.env.development?
        dont run me during testing
    end

the code gets executed regardless of which environment I am in. I&#39;ve even tried:

    if Rails.env.development? and not Rails.env.test?
        NO, REALLY, DONT RUN ME DURING TESTING
    end

but no love.

What should I be doing instead?



How can I determine if my rails is in the development environment and not the test environment?

I have an issue with connecting environment to my Spring project.
In this class 

    @Configuration
    @ComponentScan(basePackages = &quot;my.pack.offer.*&quot;)
    @PropertySource(&quot;classpath:OfferService.properties&quot;)
    public class PropertiesUtil {

        {
            return environment.getRequiredProperty(propertyName);
        }
    }

I was looking for a way to set the environment path variable with a .cmd file.  
When the path variable was getting too long, I got some errors.  
Just add the needed variables to &#39;Set Path variable&#39; below  
Check the current value of your path variable and add to the script  
**Run the script as administrator!**  
Open a new console window and it should work e.g. php -v

I want to add a conda channel to a specific [conda environment](http://conda.pydata.org/docs/using/envs.html) but when I use 

    conda config --add channels glotzer

that channel is now available from all my conda environments.  In addition to testing an install from another environment, the `~/.condarc` file has the following:

    channels:
      - glotzer
      - defaults

How would I configure conda so the channel is only available from a specific environment?

I did find in the [channel documentation](http://conda.pydata.org/docs/channels.html) that for conda &gt;= 4.1.0, putting channels at the bottom of the `~/.condarc` will prevent added channels from overiding the core package set.

&gt; By default conda now prefers packages from a higher priority channel over any version from a lower priority channel. Therefore you can now safely put channels at the bottom of your
&gt; channel list to provide additional packages that are not in the
&gt; default channels, and still be confident that these channels will not
&gt; override the core package set.

I expect this will prevent most problems, except when in one environment you do want the package added through a channel to override a core package.
