It stands for File System ChecK. The name is taken from the Unix [`fsck`](http://linux.die.net/man/8/fsck) command, which is used to validate a file system.

It was first called:

- [`fsck-cached`][1] (git 0.99), to check the repository for errors
- then [`fsck-objects`][2] (git 0.99.8), in order to report what exactly is wrong with the object, instead of an ambiguous &#39;bad sha1 file&#39;.
- and finally [`git fsck`][3] (git 1.5.0, January 2007)

It reflects that Git was initially built as a file system, with a graph of nodes and [`git fsck`][4] is presented in this [GitHub Training][5] as a **file system check** which verifies integrity and finds corrupt objects.

I try to verify a CSV file where we had problems with line breaks.

I want to find all lines not starting with a `&quot;`.

I am trying with `/!^&quot;/gim` but the `!` negation is not working.

How can I negate `/^&quot;/gim` properly?

I am having a hard time finding clang-format and clang-format.py on my Mac OS 10.8.5 with Xcode 5 and its Command Line Tools. I tried `find / -name &quot;clang-format.py&quot;` without luck. Are they already here somewhere hiding, or how would I get this toolchain?

(I&#39;m surprised it doesn&#39;t seem readily available since clang is Apple&#39;s compiler---in that Apple uses it.)

Where are clang-format and clang-format.py in Mac OS X with Xcode Command Line Tools installed?

What is the meaning in behind the `fsck` command name?

The [documentation][1] of the command does not seem to mention what the name stands for.

I have created two GitHub accounts.  One for my work user and one for my personal self.  I needed to do catch up on some work and as such cloned my work repo onto my personal PC.  In order to do simple &quot;git push origin master&quot; commits without entering my username and password the whole time I simply want to add my public key from my home pc to the work repo.  However Github gives this error:

    Error: Key already use

After a bit of Googling I came across this [link][1] which states &quot;To resolve the issue, remove the key from the other account or repository and add it to your account&quot;  Of course there is a duplicate key as I&#39;ve added my home public key to github so that I can code on my own personal projects. After all I want to be able to code to my work repo using both my work pc and personal pc.

How can you add multiple &quot;same&quot; public keys without Github throwing that error and also why in the world, is that error thrown in the first place?

**How do I discard all git commits that haven&#39;t been pushed and then force git to not commit anything in the data/ directory?**

I&#39;m trying to force overwrite all changes to a project stored on github from my c9.io project.  I accidentally git added some mongodb data files.  I tried to add the data/ directory to .gitignore. I pulled from github to get the updated .gitignore, however when I try and git push, these stubborn files in data/ are still staged for commit.  I also tried git reset, git rebase, git clean and [this](http://www.thisprogrammingthing.com/2013/fixing-the-this-exceeds-githubs-file-size-limit-of-100-mb-error/) where I changed dmpfile.sql to pi/data/node-login.1.

Please help I&#39;ve been at this for hours and I&#39;m really frustrated

Can&#39;t remove file from git commit

We have a fairly simple node.js app, but due to AWS Elastic Beanstalk deployment mechanism, it takes about 5 minutes to roll-out a new version (via `git aws.push`) even after a single file commit.

I.e. the commit itself (and upload) is fast (only 1 file to push), but then Elastic Beanstalk fetches whole package from S3, unzips it and runs `npm install`, which causes node-gyp to compile some modules. Upon installation/building completion, Elastic Beanstalk wipes `/var/app/current` and replaces it with the new app version.

Needless to say, constant node_modules rebuilding is not necessary, and rebuilding that takes 30 seconds on my old Macbook Air, takes &gt;5 mins on a ec2.micro instance, not fun.

I see two approaches here:

 1. tweak `/opt/containerfiles/ebnode.py` and play with node_modules location to avoid its removal and rebuilding upon deployment. 
 2. set up a git repo on Elastic Beanstalk EC2 instance and basically re-write deployment procedure ourselves, so /var/app/current receives pushes and runs `npm install` only when necessary (which makes Elastic Beanstalk to look like OpsWorks..)

Both options lack grace and are prone to issues when Amazon updates their Elastic Beanstalk hooks and architecture.

Maybe somebody has a better idea how to avoid constant rebuilding of node_modules that are already present in the app dir? Thank you.

I&#39;m using the Git Bash in Windows and for the purposes of my custom `git log` format, I&#39;d like to modify the terminal&#39;s exact RGB color values so I can fine-tune the color outputs. My git log format is as follows in my global `.gitconfig`:

    lg1 = log --graph --abbrev-commit --decorate --date=relative --format=format:&#39;%C(bold blue)%h%C(reset)%x09%C(bold green)(%ar)%C(reset)%C(bold yellow)%d%C(reset) %C(dim white)%an%C(reset) - %C(white)%s%C(reset)&#39; --branches --remotes --tags

I&#39;d like to define in Git Bash what RGB value actually maps to &#39;blue&#39;, for example. Any idea how I can do this? Step by step instructions would be wonderful. Thanks in advance.

EDIT
----
I setup my .bashrc and it isn&#39;t working for some reason. Colors aren&#39;t changing :-(. Here is a script I ran to see colors: http://pastebin.com/9EsYmGCj and the result: http://i.imgur.com/1dJ3o1a.png
