How to Use Git Shell Commands?

Git is a powerful version control system that is important for managing source code in modern software development. While there are many graphical user interfaces (GUIs) available for Git, mastering Git shell commands can significantly enhance your productivity and control over your repositories. This article provides an overview of essential Git shell commands and how to use them effectively.

Steps to Use Git Shell Commands

Below is the general workflow when using Git Bash:

Step 1: Open Git Bash

Launch the Git Bash application on the system.

Step 2: Navigate to the Project Directory

Use the cd command to change the current working directory to the location of the project.

cd path/to/your/project

For Example

Initialize a Git Repository

If it isn't done already, run git init to create a new Git repository in the project directory.

git init

Output

Add Files to the Staging Area

Use git add <file_name> to add specific files, or git add . to add all changes in the current directory to the staging area.

git add <file_name>
# or
git add .

Output

Commit Changes

Run git commit -m "commit message" to save the staged changes with a descriptive commit message.

git commit -m "commit message"

Output

View Commit History

Use git log to see a list of past commits with their associated messages and details.

git log

Output

Create Branches

Execute git branch <branch_name> to create a new branch.

git branch <branch_name>

For Example:

Switch Branches

Use git checkout <branch_name> to switch to a different branch.

git checkout <branch_name>

For Example

Merge Branches

Run git merge <branch_name> to merge changes from one branch into another.

git merge <branch_name>

For Example

Push Changes to a Remote Repository

If we're collaborating with others, use git push <remote_name> <branch_name> to upload our commits to a remote repository (e.g., on GitHub or GitLab).

git push <remote_name> <branch_name>

For Example

Pull Changes from a Remote Repository

Run git pull <remote_name> <branch_name> to download and integrate changes from the remote repository into the local branch.

git pull <remote_name> <branch_name>

For Example

Check the Current State

Use git status to check the current state of the repository and see which files have been modified or staged.

git status

Output

Explore other Git commands like git rebase, git stash, git reset, and git tag for more advanced operations.

Note: To install Git Bash see this.

Conclusion

In conclusion, git shell commands provide a powerful and flexible way to interact with the Git version control system. Using this, we can effectively manage our codebase, collaborate with others, and maintain a clear history of our project's development.
