Git Contd

Git identifies changes w.r.t files not folders. Empty folder is not a change in git.
We can configure git to ignore some files or folders. To do this we need to create a file called as .gitignore in the root folder of the repository. To create ignore based on tools and languages Refer Here
Exercise:
- Create git ingore files for the following combinations
  - Java:
    - IDE: Eclipse
    - Build: Maven
  - Dotnetcore:
    - IDE: Visual Studio
  - ReactJs:
    - IDE: visual studio code
  - Terraform:
    - IDE: visual studio code
  - Ansible:
    - IDE: visual studio code

Moving Changes from staging area to working tree and remove the changes from working tree

Ensure only main.py is committed
History
Remove the app.py changes from working tree
Revisit Git Areas
To remove all the untracked files from a specific folder

git clean -fd <path>

* We have executed git reset --hard
* We have two other flavors of git reset
* soft
* mixed
* I will be discussing on when to use what in next 3 days
* When we execute git status and git log along with status we see one extra term master

* By default master always looks at latest commit and HEAD represents what your working tree is looking at

* Lets move our head to 2 commit
