git checkout FETCH_HEAD path/to/file/or/folder

Add / Commit / Push

# Add All Files

git commit -m "message for commit"

# Push
git push origin <branch>

# Push Folder to Subtree
git subtree push --prefix <folder> origin <branch>

Delete History

git filter-branch --tree-filter 'rm -rf <folder>' --prune-empty HEAD
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
git commit -m '<message>'
git gc
git push origin master --force

Special Functions

# Create Bare Repository
mkdir repository.git
cd repository.git
git init --bare

Notes

Bare repositories don't have a working tree (no history of modifications and changes), so you can't add files to them using git add or git commit. Instead you commit a bare repository by pushing to it from your local clone. To have central repository the only way it is to have a bare repository.
