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

git checkout <commit-id>

* To go back to latest commit

git checkout master
