If you're working on a project with multiple contributors, you'll likely run into situations where you need to merge changes from different branches. Before merging, it's important to commit your changes or stash them to avoid losing any work. In this guide, we'll cover how to commit changes or stash them before merging.
Committing Changes
Committing changes is the process of saving your work to the local repository. When you commit changes, you create a new version of your code that you can revert to if necessary. Here are the steps to commit changes:
- Open your terminal or command prompt.
- Navigate to the directory where your project is located.
- Use the
git addcommand to stage your changes. For example, if you've modified a file calledindex.html, you would rungit add index.html. - Use the
git commitcommand to commit your changes. You can add a message to describe your changes by using the-mflag followed by your message in quotes. For example,git commit -m "Updated the homepage content." - After committing your changes, you can push them to the remote repository using the
git pushcommand.
Stashing Changes
Stashing changes is similar to committing changes, but it's used when you're not ready to commit your changes yet. When you stash changes, you save them to a temporary location so that you can retrieve them later. Here are the steps to stash changes:
- Open your terminal or command prompt.
- Navigate to the directory where your project is located.
- Use the
git stashcommand to stash your changes. - After stashing your changes, you can switch to a different branch or pull changes from the remote repository.
- When you're ready to retrieve your stashed changes, use the
git stash applycommand to retrieve them. If you have multiple stashes, you can specify which one to retrieve by usinggit stash apply stash@{n}wherenis the number of the stash you want to retrieve.
