## Context
A number of my application user configuration files are kept in a git repository for easy sharing across multiple machines and multiple platforms. Amongst these configuration files is `.gitconfig` which contains the following settings for handling the carriage return linefeed characters

    [core]
	    autocrlf = true
	    safecrlf = false
## Problem
These settings also gets applied on a GNU/Linux platform which causes obscure errors. 

## Question
What are some best practices for handling these platform specific differences in configuration files? 

## Proposed solution
I realize this problem could be solved by having a branch for each platform and keeping the common stuff in master and merging with the platform branch when master moves forward. I&#39;m wondering if there are any *easier* solutions to this problem?

Best practices for cross platform git config?

I followed [these instructions](https://help.github.com/articles/set-up-git) to the letter, including the part about password caching. It seems like the instructions are wrong, because every time I `git push origin master` I get this error:

    git: &#39;credential-cache&#39; is not a git command. See &#39;get --help&#39;.

... at which point I am forced to enter my username and password. After doing so, I am presented with the same error message again, followed by the output from `git push`.

Here is the contents of my .gitconfig file:

    [user]
        name = myusername
        email = myusername@myemaildomain.com
    [credential]
        helper = cache

To be clear, after I installed Git and ran Git Bash, here is exactly what I typed:

    git config --global user.name &quot;myusername&quot;
    git config --global user.email &quot;myusername@myemaildomain.com&quot;
    git config --global credential.helper cache

Please help. This is so frustrating!

git: &#39;credential-cache&#39; is not a git command

I am trying to make a commit like

&lt;!-- language: lang-bash --&gt;

    git commit --author=&quot;John Doe &lt;john@doe.com&gt;&quot; -m &quot;&lt;the usual commit message&gt;&quot;

where John Doe is some user in whose name I want to make the commit.

It appears all right in `git log`. However, when I do a `gitk`, **the author name is correct, but the committer name is picked from my global git config settings** (and is thus set to my name/email).

## Questions

1. What is the difference between the two (committer vs author)?

2. Should I be setting the committer as well to the other user?

3. If yes, how?

I have a Git repository. I have cloned the repository and can commit my local changes. When I push my changes to the server it works.

As soon as I create a branch, I checkout the branch, commit my work and then checkout the master branch. I then merge my local changes into the master branch. When I try to push to the server I get the following exception:

What I would really like to do is create branches, merge them into the master branch and then push my changes to the server.

Similar to the MySQL `show variables` command that shows all variables and not just the ones defined in `my.ini`, I would like to see a list of **all** config variables in `git` **along with** their default values, and not just those defined in my `~/.gitconfig`. 

Is this possible?

I&#39;m behind a firewall that is blocking port 9418 (git) and am trying to install some tools that are explicitly doing a checkout of `git://github.com/...`, so I can&#39;t switch to https for the checkout.

So I&#39;m wondering if it&#39;s possible to redirect all traffic to port 9418 through a proxy and if so how :)

git:// through proxy

I use two different git emails, one for work and one for public projects. Initially I thought that I could create a separate .gitconfig with a different email in a folder where all my public repos are in, and that git would respect that, but alas it seems that doesn&#39;t work. What&#39;s the best way to easily setup something similar? I want to avoid having to specifically change the email in each public repo.

Different .gitconfig for a given subdirectory?

I&#39;m using Git on Windows, on a corporate network where I&#39;m behind an HTTP proxy with Basic authentication. Outbound SSH doesn&#39;t work, so I have to use HTTPS through the proxy.

I&#39;m aware of how to use `git config http.proxy` to configure the settings as `http://[username]:[password]@[proxy]:[port]`.

However, particularly as this is a shared machine, I&#39;d rather not store my password in my `.gitconfig`. Additionally, changing my `.gitconfig` using the `git config` command leaves my password in my bash history, so even if I remember to clear my `.gitconfig` at the end of the session, I&#39;ll almost certainly forget to clear my history as well.

I&#39;ve tried setting `http.proxy` without a password, in the vain hope that I&#39;d get a prompt asking me for my password when I try to push/pull, but I only get a 407 Proxy Authentication Required. All the information I&#39;ve found online seems to either ignore the issues with having the password saved in plaintext in `.gitconfig`, or deals with NTLM proxies.

I&#39;m quite happy to type my proxy details every time I need to connect - the best solution I can see at the moment is writing a wrapper script that will prompt for my password and set that as an environment variable when calling `git` proper. Is this a decent solution, and are there any security implications to setting an environment variable for a single call in a script? Preferably, are there any built-in settings or existing tools that I can use for this?

Using Git on Windows, behind an HTTP proxy, without storing proxy password on disk

I used git for the first time and I set my user name and user mail. The commands I used are below:

    git config --global user.email &quot;bob@example.com&quot;
    git config user.email &quot;bob@example.com&quot;
    git config --global user.name &quot;bob&quot;
    git config user.name &quot;bob&quot;

When I run `git commit --author &quot;bob&quot;` , I got an error `fatal: No existing author found with &#39;bob&#39;`. How can I set user name and email?

fatal: No existing author found with &#39;XXX&#39;

I have a global git user configured, but want to use a different user for a single git project.

Within that project, I&#39;ve used `git config --local user.name &quot;localuser&quot;` and `git config --local user.email &quot;localuser@example.com&quot;` to set the local project&#39;s user and email.

However, when I try to push to my remote on github, I get this error:

    remote: Permission to localuser/repo.git denied to globaluser.
    fatal: unable to access &#39;https://github.com/localuser/repo.git/&#39;: The requested URL returned error: 403

Here&#39;s some output that might help with diagnosis:

`git remote -v`:

    github	https://github.com/localuser/repo.git (fetch)
    github	https://github.com/localuser/repo.git (push)

`git config --list`:

    user.name=globaluser
    user.email=globaluser@example.com
    ...

`git config --local --list`:

    user.name=localuser
    user.email=localuser@example.com
    ...

`git config user.name`:

    localuser


Local git config not overriding global user for project

I have a problem setting Sublime Text 2 as the `core.editor` with `git`.

I&#39;ve read through every post I could find addressing the problem, but still nothing is working for me. I am running Windows.

I have done:

    git config --global core.editor &quot;&#39;C:/Program Files/Sublime Text 2/sublime_text.exe&#39;&quot;

and tried that with various arguments like `-m`.  When I open my `.gitconfig`, this is what is in there:

    [user]
	    name = Spencer Moran
	    email = smoran02@gmail.com
    [core]
	    editor = &#39;C:/Program Files/Sublime Text 2/sublime_text.exe&#39;


If I go to Git and type:

    README.markdown --edit

the README file opens in Notepad, not Sublime Text.

Does anyone have any idea what I&#39;m doing wrong or how I could fix this?


How can I make Sublime Text the default editor for Git?

In my `~/.gitconfig`, I list my personal email address under `[user]`, since that&#39;s what I want to use for Github repos.

But, I&#39;ve recently started using git for work, too. My company&#39;s git repo allows me to commit, but when it sends out announcements of new changesets, it says they are from Anonymous because it doesn&#39;t recognize the email address in my `.gitconfig` - at least, that&#39;s my theory.

Is it possible to specify multiple `[user]` definitions in `.gitconfig`? Or is there some other way to override the default `.gitconfig` for a certain directory? In my case, I check out all work code in `~/worksrc/` - is there a way to specify a `.gitconfig` for only that directory (and its subdirectories)?

Can I specify multiple users for myself in .gitconfig?

With Git, when using the `autocrlf = true` flag, a warning is still given when line-endings are changed.

I understand what the warning is for, and how to turn off the line-ending flag, but how do I turn off the warning itself?

With Git, how do I turn off the &quot;LF will be replaced by CRLF&quot; warning

I have a different git repository for my office and a different git repo for my hobby projects. 

When I do `git config --global user.name`
the user name changes globally and this creates a confusion
of committing to a repo with user name. 

Hence the question is how can i have the same username across all my hobby projects and 
the same username across the office projects. I use the same machine to work on both the places.

git multiple user names for the different projects within the same system

Somewhen (around the 1.6.x releases, I think) git became aware of changes inside submodules. That only serves to annoy me:


&lt;pre&gt;
$ git status vendor | grep modified:
#       modified:   vendor/rails (modified content)
&lt;/pre&gt;

&lt;pre&gt;
$ git diff vendor/
diff --git a/vendor/rails b/vendor/rails
--- a/vendor/rails
+++ b/vendor/rails
@@ -1 +1 @@

&lt;/pre&gt;

Please make it stop?

### Edit:

Ok, so I have an answer. Now I have another question:

Can I put this in `~/.gitconfig`? From my initial it appears that I cannot, and I didn&#39;t see anything promising by skimming the patch. (I guess I can still make an alias.)

Git: can I suppress listing of &#39;modified content&#39;/dirty submodule entries in status, diff, etc?

Functionally speaking, in a decentralized workflow, I don&#39;t see the difference between `simple` and `current` options for `push.default` config setting.

`current` will push the current branch to an identically named branch on the specified remote. `simple` will effectively do the same thing as well for both the tracked and any untracked remotes for the current branch (it enforces identical branch names in both cases).

Can someone explain any important differences between the two for decentralized workflows that I am missing?

I use my personal laptop for both work and personal projects and I would like to use my work email address for my commits at work (gitolite) and my personal email address for the rest (github).

I read about the following solutions which are all either global or temporary:

 - `git config --global user.email &quot;bob@example.com&quot;`
 - `git config user.email &quot;bob@example.com&quot;`
 - `git commit --author &quot;Bob &lt;bob@example.com&gt;&quot;`
 - setting one of the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL` or `EMAIL` environment variables

One solution is to run manually a shell function that sets my environment to *work* or *personal*, but I am pretty sure that I will often forget to switch to the correct identity resulting in committing under the wrong identity.

Is there a way of binding a certain repository, project name, etc. to an identity (name, email)? What do people do?

I could probably setup an alias, but it seems like I should be able to set this as an option in the config file, only I don&#39;t see anyway to do it.

I only want the `--ignore-space-change` when I&#39;m doing diff, not when I&#39;m doing apply or anything else.  I&#39;m trying to make the diff easier to understand by not cluttering it with with extraneous +/- lines that have no real changes on them.

I am aware that the default rename limit is 100 and we can increase this value using the config `diff.renamelimit config`

What I am worried about is that, if this config is not setup, will there be a wrong merge or any missing code?
I am trying to merge (git merge) 2 branches that have huge changes. 

Can someone throw more light about this config setting?

    rb3 = rebase -i HEAD~3
    rb4 = rebase -i HEAD~4

I was pushing and pulling from git in Terminal then I changed my username on github.com.  I went to push some changes and it couldn&#39;t push because it was still recognizing my old username.. How do I change/update my username on git in terminal?



How to change my Git username in terminal?

While configuring `git` I ran these two commands:

    git config --global user.name &quot;My Name&quot;

    git config --global user.email &quot;myemail@example.com&quot;

However, I doubt whether I made a typo or not. So, is there any command to know the **name** and **email** which `git` saved during configuration? Obviously, I can know that using the `git log` command by looking at the commit history. But for that I have to make commits, right? Can I know that with the help of command line?

How to know the git username and email saved during configuration?

In making my favorite git log view I&#39;ve created this alias:

`graph = log --pretty=format:&#39;%Cgreen%ad%Creset %C(yellow)%h%Creset%C(yellow)%d%Creset %s %C(cyan)[%an]%Creset %Cgreen(%ar)%Creset&#39; --date=short --graph`

This creates an output like:

![Git log result with own coloring][1]

What I&#39;m missing here is the different coloring of branch types like in `log --oneline --decorate --graph`.

![Git log result with --decorate(=short)][2]

The --decorate (which uses =short by default) gives the different recognized branches a different color. The branch types `(HEAD, origin/master, origin/HEAD, master)` are colored cyan, red, red, green. Mine however are uncolored; colored only with the yellow of the whole branches part.

**Is there a way to give different colors to the different _kind_ of branches with an own alias?**
