Git Cheat Sheet

• Initialize a git repo

  git init
  

• Add files to the staging area

    git add fileName
    OR
    git add .
  

  The git add . command is used to add all the files to the staging area.

• Commit staged changes

    git commit -m "message for the commit"
  

• View commit history

    git log
  

• Create a new branch

    git branch branch-name
  
    git checkout -b new-branch
  
    git switch -c branch-name
  

  The checkout and switch command creates a new branch and switches to the created branch but the branch command does-not switch the branch automatically.

• Merge two branches

    git merge
  

  For git merge to work properly you should be located in the branch where the additional information from the other branch should be added to. Suppose we need to merge branch-3 to the main branch then we should be in the main branch.

• Delete Branches

  git branch -d/-D branch-name
  

  The git branch -d/-D branch-name is used to delete a specific branch. The small -d will only allow you to delete branches if you merge these branches. The capital -D will force the deletion, this means the branch will be deleted, no matter if you merged it or not.

A great resource for understanding git.
