GIT COMMANDS

Want to create a new branch

   git checkout -b branch-name
   # when you run this command it will take checkout from branch in which you currently are.

Having merge conflicts, no worries resolve with mergetool

    git mergetool

Want to push, pull and merge the code.

    git pull origin branch-name

    git add file-name

    git commit -m "commit-message"

    git push origin branch-name

    git merge branch-name

Want to rename git local and remote branches

1. Rename your local branch.

   If you are on the branch you want to rename:
   
   git branch -m new-name
   If you are on a different branch:
   
   git branch -m old-name new-name
   

2. Delete the old-name remote branch and push the new-name local branch.

   git push origin :old-name new-name

3. Reset the upstream branch for the new-name local branch.

   Switch to the branch and then:
   
   git push origin -u new-name
   
   ## Or you as a fast way to do that, you can use these 3 steps: command in your terminal
   
      git branch -m old_branch new_branch         
      # Rename branch locally    
   
      git push origin :old_branch                 
      # Delete the old branch    
   
      git push --set-upstream origin new_branch   
      # Push the new branch, set local branch to track the new remote

4. Delete local branch and then the remote branch.

   git branch -d branch_name   
   # The -d option stands for --delete, which would delete the local branch, 
   only if you have already pushed and merged it with your remote branches.
   
   git branch -D branch_name
   # The -D option stands for --delete --force, which deletes the branch regardless 
   of its push and merge status, so be careful using this one!
