GIT Notes for the Interview PART-2
After the basics of GIT like cloning the repository, creating a branch in the previous post, now we will look at how to add files, commit and push your changes.
Once you are done with writing your code or changes to existing code or module, you need to add files that you have changed into the staging area
To check which files you need to add, write this command
git status
This command is used to check the current status of your local branch, which files are ready to be committed, and which files need to be added to the staging area for commit.
You will see some files in Red color
modified : folder/xyz/abc.cpp
This file is not added to the staging area, so you need to add the files using the command
git add folder/xyz/abc.cpp
Once you are done with adding the file in the staging area, your file is ready for the commit. For commit use the following command
git commit -m "Added condition for denominator not equal to zero in abc.cpp"
here you can use -m and comment in double-quotes about the code/change you have added.
After you have committed your code locally, its time to push your changes to the remote repository so that other developers can use your changes.
But before pushing, you need to pull the latest changes made by developers on the remote repository, so that your local repository is in sync with the remote repository and then you push your changes thus avoiding any conflicts and issues. You can use the below commands in the given order
git pull
git push
Note that you can only use the above commands directly when your local branch is tracking the remote branch already. If your local branch is not tracking the remote branch then these commands will not work.
We will see more about remote-tracking branches and how to create them in my next post.
