## Git


#### Scenario 1: Need to remove a Modified File from Git pull request

Switch to the branch from which you created the pull request:

     git checkout pull-request-branch

Overwrite the modified file(s) with the file in another branch, let's consider it's **master**:

    git checkout origin/master -- src/main/java/HelloWorld.java

Commit and push it to the remote:

    git commit -m "Removed a modified file from pull request"
    git push origin pull-request-branch

#### Scenario 2: Update the commit user name and email in the respective Git repo.

    git config user.name user-name
    git config user.email username-git@gmail.com

#### Scenario 3: Git updating the buffer size in Git repo, helps in case a large file is present in Git and you are trying to clone it in the local system.

    git config --global http.postBuffer 1048576000

#### Scenario 4: Stop tracking changes to a file in Sourcetree.

I guess This is the issue which troubled me most in git. Let's say, I have a file in my code base that I don't want to commit as this is specific to my local. But still, Sourcetree shows this file to me, every time I try to commit. This is really very annoying. to fix this run the below command in the repo folder and the Sourcetree will understand our feelings.

    git update-index --assume-unchanged file.filename

For folder use this

    git rm -r --cached path_to_your_folder/

To get undo/show dir's/files that are set to assume-unchanged run this:

    git update-index --no-assume-unchanged file.filename

To get a list of dir's/files that are assume-unchanged run this:

    git ls-files -v|grep '^h'
    
 To delete all local checked out branches
 	
	git branch -D `git branch`
