Everyday Git (Git commands you need in your everyday work)

Git [1] is one of the most popular version control systems. In this post I am going to show you how to work with GitHub [2]. When it comes to GitHub there are thousands of public repositories. If you are interested in a project you can start working on it and contributing it. Followings are the steps and commands you will have to use while you work with GitHub.

1. Forking a repository
This is done via the GithHub [2] web site.

2. Clone a new repository

git clone https://github.com/jsdjayanga/carbon4-kernel.git

3. Get updates from the remote repository (origin/master)

git pull origin master

4. Push the updates to the the remote repository (origin/master)

git push origin master

5. Add updated files to staging

git add TestFile.java

6. Commit the local changes to the remote repository

git commit -m "Modifications to TestFile.java" --signoff

7. Set the upstream repository

git remote add upstream https://github.com/wso2/carbon4-kernel.git

8. Fetch from upstream repository

git fetch upstream

9. Fetch from all the remote repositories

git fetch --all

10. Merge new changes from upstream repository for the master branch

git checkout master
git merge upstream/master

11. Merge new changes from upstream repository for the "otherbranch" branch

git checkout otherbranch
git merge upstream/otherbranch

12. View the history of commits

git log

13. If needed to discard some commits in the local repository
First find the commit ID to which you want to revert back to. The user the following command

git reset --hard #commitId

14. To tag a particular commit

git checkout #commitid
git tag -a v1.1.1 -m 'Tagging version v1.1.1'
git push origin --tags
