What are some common Git commands I should know?
When using Git Bash, there are several essential Git commands that every user should become familiar with. The most fundamental command is git clone, which allows you to copy a remote repository to your local machine. The git status command is also crucial, as it helps you monitor the state of your working directory and staging area to see which files have been modified or are untracked.
Other important commands include git add, which stages changes for the next commit, and git commit, which records your staged changes. Additionally, git push uploads your local commits to the remote repository on GitHub, while git pull fetches and integrates the latest updates from the remote repository into your local copy. Mastering these commands will help you efficiently manage your projects and collaborate with others on GitHub.
How do I resolve conflicts when using Git Bash?
Conflict resolution is an essential skill when working with Git, especially when collaborating with multiple developers. A merge conflict occurs when changes made to the same line of the same file differ between branches. When Git encounters such differences, it will pause the merge process and indicate that a conflict needs to be resolved. You can check for conflicts by executing the git status command after a failed merge.
Resolving conflicts typically involves manually editing the conflicting files to combine changes from both versions. When you open a file with conflicts, you will see conflict markers indicating the changes. Once you have made the necessary adjustments, save the file and use the git add <file> command to stage the resolved file. Following this, complete the merge by executing git commit, which will finalize the update in your repository. Understanding how to handle conflicts is vital for maintaining a clean and functional codebase during collaborative work.
