$ cd webapp/

rgupta99@LIN-5CG2217BB4 MINGW64 ~/Desktop/Raj/hello-world-1/webapp/src/main/webapp (master)

$ ls

WEB-INF/  index.jsp

$ vi index.jsp

3.  Check the git status

rgupta99@LIN-5CG2217BB4 MINGW64 ~/Desktop/Raj/hello-world-1/webapp/src/main/webapp (master)

$ git status

On branch master

Your branch is up to date with 'origin/master'.

Changes not staged for commit:

  (use "git add <file>..." to update what will be committed)

  (use "git restore <file>..." to discard changes in working directory)

        modified:   index.jsp

no changes added to commit (use "git add" and/or "git commit -a")

4.  Add all changes to local repo

rgupta99@LIN-5CG2217BB4 MINGW64 ~/Desktop/Raj/hello-world-1/webapp/src/main/webapp (master)

$ git add .

rgupta99@LIN-5CG2217BB4 MINGW64 ~/Desktop/Raj/hello-world-1/webapp/src/main/webapp (master)

$ git status

On branch master

Your branch is up to date with 'origin/master'.

Changes to be committed:

  (use "git restore --staged <file>..." to unstage)

        modified:   index.jsp

5. Saves changes to the local repository with a message.:-
