What is the difference between git pull and git fetch in Salesforce?

Hello Prachi

Git pull command pulls new changes or commits from a particular branch from your central repository and updates your target branch in your local repository.

Git fetch is also used for the same purpose but it works in a slightly different way. When you perform a git fetch, it pulls all new commits from the desired branch and stores it in a new branch in your local repository. If you want to reflect these changes in your target branch, git fetch must be followed with a git merge. Your target branch will only be updated after merging the target branch and fetched branch. Just to make it easy for you, remember the equation below:

git pull = git fetch + git merge

Adding some points:

A bare repository is nothing but the .git folder itself i.e. the contents of a bare repository is same as the contents of .git folder inside your local working repository. Use bare repository on a remote server to allow multiple contributors to push their work.

Thanks
