How to Change Directories in Your Terminal When Working with Git?

Changing directories is a fundamental command-line operation performed using your operating system's terminal or command prompt, not directly via a Git command. Git commands operate within the current working directory you are in.

Understanding the `cd` Command

To change your current working directory, you use the cd command (which stands for "change directory"). This command is a part of your shell (like Bash, Zsh, PowerShell, or Command Prompt), allowing you to navigate through your file system.

For instance, to move one directory upwards (into the current folder's parent folder), you would simply call:

$ cd ..

This command takes you from your current location to the directory directly above it in the file system hierarchy.

Why Directory Navigation Matters for Git

Git is a version control system that tracks changes within a specific project folder, known as a Git repository. For Git commands to work correctly, you must be inside the relevant Git repository's directory (or a subdirectory of it) in your terminal. If you try to run Git commands like git status, git commit, or git pull outside of a Git repository, you will receive an error message indicating that it's "not a git repository."

Therefore, mastering the cd command is crucial for any developer using Git, as it allows you to:

Navigate to your cloned repositories.
Move into specific project subfolders.
Create new repositories in desired locations.

Essential `cd` Commands for Git Users

Here's a breakdown of common cd commands and their practical applications when working with Git projects:

Command	Description	Example Use Case
`cd folder_name`	Moves into a specified subfolder within your current directory.	`cd my-project` (to enter the `my-project` folder)
`cd ..`	Moves up one directory level to the parent folder.	If in `my-project/src`, `cd ..` takes you to `my-project`.
`cd /path/to/directory`	Navigates directly to an absolute path, regardless of your current location.	`cd /Users/username/Documents/repos/my-project`
`cd ~` (Linux/macOS)	Returns to your user's home directory.	`cd ~` (often `C:\Users\username` on Windows)
`cd -` (Linux/macOS)	Jumps to the previous working directory you were in.	Quickly switch back and forth between two frequently used directories.
`cd \` or `cd /` (Windows/Linux)	Navigates to the root of the current drive (Windows) or the file system root (Linux).	`cd \` (Windows C: drive root), `cd /` (Linux root directory)

Practical Steps for Git Workflow

To effectively use Git, follow these steps to ensure you are in the correct directory:

Open your terminal or command prompt. This is where you'll type your cd and Git commands.
Navigate to your desired project directory. Use the cd command to move to the specific folder where your Git repository is located, or where you intend to initialize a new one.
- Example: If your repository is located at C:\Users\YourName\Documents\GitHub\my-awesome-repo, you would type:
```
cd C:\Users\YourName\Documents\GitHub\my-awesome-repo
```
  Or, if you're already in Documents:
```
cd GitHub/my-awesome-repo
```
Verify your current location.
- On Linux/macOS, use pwd (print working directory).
- On Windows, simply typing cd (without any arguments) will display your current path.
Execute Git commands. Once you are in the correct directory, you can confidently run any Git commands relevant to your repository, such as git status, git pull, git add ., git commit -m "My message", or git push.
