Useful git commnads

Git is a version control system which is used by most open source and collaborative programming projects. Below is a list of few very often used git commands. Hope its helpful.


1. Get the status of modified files
$ git status

2. Pull latest changes in current branch
$ git pull origin master

3. Switch to existing branch
$ git checkout branch-name

4. Checkout into your new branch
$ git checkout -b myNewBranch

5. Delete branch
$ git branch -D myLocalBranch

6. Show all branches, local and remote
$ git branch –a

7. Git reset/discard all changes until last commit

$ git reset –hard
$ git checkout -f

$ git reset --hard origin/master

for moving to the head version

8. Applying the patch on current branch.

Note: You first need to check if patch has some conflicts. If there are no conflicts then only apply patch.
$ git apply --check ../DRILL-154.patch
$ git apply ../DRILL-154.patch

Verify if patch is applied:
$ git status

9. Add files to version control
Get list of files to be added to version control by ‘git status’ and then add the files one by one:
$ git add sandbox/web-frontend/drill.css

10. Finally commit files to branch

$ git commit -m "Your commit message here"

$ git commit -m “DRILL-154: Comment-Drill logo added in modal window”

11. Configure userid and email id for git commits (if not present in configs already)

$ git show 74a27b95ad83eb2eb69d76d17c97667ceac82283

14. Create patch from commit id
$ git show 74a27b95ad83eb2eb69d76d17c97667ceac82283 > DRILL-154.patch


Few Other Commands:
