GIT Command Lines

These are the Git command lines that I have used frequently in the project.

Switch to a new branch:

git checkout -b <origin_brnach> <new_branch_name>

Add all local changes to the local repository:
```
git add .
```
Commit all local changes:
```
git commit -m"commit message"
```
The standard commit if GitLab is connected with Jira Software:
```
git commit -m"CHD-86: Update code for contract API"
```
CHD-86 is your task on Jira Software
Push commits to the remote repository:
```
git push
```
Pull code from the remote repository:
```
git pull
```
Merge your branch codes with the other branch (ex, develop):
```
git checkout <your_branch>
git merge develop
```
If it shows many conflicts, you should fix it!
Roll back to the specific commit code

Firstly, you should determine the commit that you want to roll back:
```
git log --oneline
```
The result will show:

The next step is to roll back to the commit:

     git reset --hard <commit_hash>

For example, commit_hash is 256cd72, which you want to go back to.

(Optional) If you want to push your code to the remote repository:

     git push origin --force

Create a new MR to revert a specific commit

Step 1: Switch to main branch (ex, develop)
```
git checkout develop
```
Step 2: Check out the new branch from develop
```
git checkout -b revert-ckt-413
```
Step 3: Go to the GitLab or GitHub repository, view the commit you want to revert

For example, I had requested to create a new MR to revert CKT-413, which had been merged into develop. I will choose to commit that my leader had merged. (now at 14/08/2025)

       git revert -m 1 351a6bc6

Hint: Choose to commit that the leader had merged into the main branch

Step 4: Push the revert branch to the repository and fix the conflict if it exists

       git push origin revert-ckt-413
