Answer 1

git status 

It will show you all modified file and new file in working tree

modified:   file path

Untracked files: that are not tracked by Git

For adding Untracked files

git add <file path>

after adding file you need to commit

 git commit -m "< your message>"

For committing only modified file

git commit -m "<your message>" <file_path 1> <file_path2>

Pushing code to git

git push <origin> <branch_name>

Update remote refs along with associated objects
