Git Switch vs. Checkout: What’s the Difference?

Introduction

git switch and git checkout are two essential commands that allow users to switch between branches in the current Git repository. ‌Navigating through a repository is important in Git as it allows users to work on different features without affecting the stable code.

The git checkout command is older, and one of its uses was creating and switching branches. The git switch command was introduced later to provide better safety checks and usability.

This tutorial will compare the two commands, list their advantages and disadvantages, and explain when to use each of the two commands.

Git switch vs. git checkout - learn the difference.

Prerequisites

Git Checkout Overview

The git checkout command is essential in the Git toolkit. It has multiple uses, including switching between branches or tags in a Git repository. It can also be used to restore files in the working tree, create new branches, or check out a single commit.

Depending on its usage, the syntax for the git checkout command is:

  • To switch branches, use the following syntax:
git checkout [branch_name]

To create a branch and switch to it, specify the -b option. For example, the following command creates a new branch called testbranch and switches to it:

git checkout -b testbranch
Switching branches in Git using git checkout.
  • To restore files in the working directory to their state from a specific commit, use the syntax below:
git checkout [commit_hash] -- [file_path]

The [commit_hash] is the unique identifier (hash) of the commit from which you want to retrieve the file.

  • To check out a commit in order to explore it without affecting any branch, use the syntax below:
git checkout [commit_hash]

Note: Learn about different Git branching strategies and see the best practices and Git branch naming conventions.

Git Switch Overview

The git switch command was introduced in Git version 2.23. The aim was to separate the functionality of git checkout into two commands – git switch for switching branches and git restore for restoring working tree files.

Thus, the primary goal of the git switch command is to switch between branches in a repository and simplify the process, making it more transparent and straightforward. It can also be used to create new branches and switch to them or the branch you were previously on.

The syntax for the git switch command is:

git switch [options] [branch_name]

The [options] are not mandatory, and they modify the command’s behavior.

What Is the Difference Between Git Checkout and Git Switch?

Although both commands can switch branches, git switch is more straightforward and explicit in its purpose. The git switch command was specifically designed to switch branches and doesn’t handle other operations like working with individual files.

In contrast, git checkout has a broader range of functionalities, which can confuse new Git users. The command allows you to switch branches and copy files from any branch to the current one. Additionally, it lets you restore changes from a particular commit.

The Git team now advises users to use git switch for branch operations and git restore for file restorations. However, both operations can be done using git checkout.

The sections below provide an overview of the different options for both commands, the advantages and disadvantages of both commands, and provide useful examples.

Git Checkout vs. Git Switch: Options

The options allow you to utilize git switch and git checkout different functionalities and control the command’s behavior. The sections below explore the available options for both commands and explain their usage.

Git Checkout

The options below provide specific functionalities when utilizing the git checkout command in Git:

Option Long Form Description
-b --branch Create a new branch and check it out.
-B Force create/recreate a branch and check it out.
--detach Detach HEAD at the specified commit and update the index and the files in the working tree.
-f --force Force checking out, discarding local changes and any untracked files or directories that are in the way.
-q --quiet Suppress feedback messages.
-t --track Create a new branch and set it to track a remote, upstream branch.
-m --merge Perform a three-way merge between the current branch, your working tree contents, and the new branch.
-p --patch Interactively select hunks from the diff between branches. Use it when selectively discarding edits from your current working tree.
--ours Resolve conflicts in favor of the current branch (ours).
--theirs Resolve conflicts in favor of the other branch (theirs)
--orphan Create a new orphan branch without any commit history. The first commit on the branch will have no parents, and it will be the root of a new history, disconnected from all other branches and commits.
--progress Show progress when checking out branches. Useful for progress reporting when not attached to a terminal.

Git Switch

The git switch command accepts the following options:

Option Long Form Description
-c [branch-name] --create Create a new branch and switch to it.
-C [branch-name] --force-create Create a new branch, even if it overwrites an existing branch.
-d --detach Detach HEAD at the specified commit.
-f --force Force switching branches, which discards local changes.
-q --quiet Suppress feedback messages.
-t --track Create a new branch that tracks a remote, upstream branch. Not specifying the -c option for the branch name derives the branch name from the remote-tracking branch.
- Switch to the previous branch.
--progress Show progress when switching branches. This option is useful when you are not attached to a terminal.

Git Checkout vs. Git Switch: Examples

This section provides useful examples for both commands. See how to utilize different options and customize the commands’ behaviors:

Git Checkout

1. Checkout to a specific commit hash:

git checkout [commit_hash]

The command switches your working tree and HEAD to the specified commit hash. For example:

Checking out a commit in Git.

Note: You can find the commit hash by running the git log command.

2. Checkout to a specific branch:

git checkout [branch_name]

This command switches your working tree and HEAD to the specified branch. For example:

Switching to a branch using git checkout.

The command checks out the new-branch branch.

3. Checkout to a specific remote branch:

git checkout -b [local_branch_name] [remote_branch_name]

This command creates a new local branch named [local_branch_name] from the specified remote branch [remote_branch_name] and switches your working tree and HEAD to the new local branch. For example:

Creating a new branch with git checkout.

4. Checkout to a specific tag:

git checkout [tag_name]

This command switches your working tree and HEAD to the commit associated with the specified tag. For example:

Checking out a tag in Git.

5. Checkout a specific file or directory:

git checkout [file_or_directory_path]

This command restores the specified file or directory to its state at the last commit. For example:

Checking out a file in Git.

In this case, the file we attempted to check out was already in the same state as the version in the last commit, so Git makes no changes.

Git Switch

1. Switch to a specific branch:

git switch [branch_name]

This command switches your working tree and HEAD to the specified branch. The command is equivalent to git checkout [branch_name]. For example:

Using git switch to switch branches.

2. Switch to a specific remote branch:

git switch -c [local_branch_name] [remote_branch_name]

This command creates a new local branch named [local_branch_name] from the specified remote branch [remote_branch_name] and switches your working tree and HEAD to the new local branch. The command is equivalent to git checkout -b [local_branch_name] [remote_branch_name]. For example:

Creating a new branch based on a remote one.

3. Move to a specific commit:

git switch --detach [commit_hash]

The --detach option in git switch moves to a specific commit without being on any branch, which puts you in a detached HEAD state. The state allows you to view, make changes, and commit, but no branch tracks the changes.

For example:

Using the detach option in git switch.

Note: Avoid making changes while in a detached HEAD state. Instead, create a new branch to make changes.

4. Switch to the previous branch:

git switch -

The command switches you to the branch you were previously on. For example:

Switching to a previous branch in Git.

Git Checkout vs. Git Switch: Advantages

Git Checkout

  • Versatility. git checkout is more versatile than git switch as it handles various operations. This includes branch switching, checking out files, checking out commits, and more.
  • Historical Use. The checkout command has been part of the Git toolkit for a long time, making it more familiar to experienced Git users.

Git Switch

  • Safety. git switch is designed specifically for branch operations. This feature reduces the risk of accidentally switching to a commit or detaching from a branch unintentionally.
  • Clear Purpose. The purpose of the git switch command is clear, which enhances readability and understanding within team workflows.
  • Improved Error Handling. git switch prevents certain operations that might lead to data loss, making it a safer choice for branch-related tasks.

Git Checkout vs. Git Switch: Disadvantages

Git Checkout

  • Potential Data Loss. git checkout can lead to data loss if misused, especially when checking out commits or unintentionally detaching from branches.
  • Ambiguity. Although versatile, the command can lead to confusion or mistakes, as it’s used for multiple purposes. Its versatility also makes it less clear in its intention compared to git switch.

Git Switch

  • No Direct Commit Checkout. The command can’t directly move to specific commits like git checkout does.
  • Compatibility. The command was introduced in Git version 2.23, which means git switch is not available in earlier Git versions. This reduces its compatibility with older Git installations.

Git Checkout vs. Git Switch: Which One Should You Use?

The choice between git switch and git checkout depends on multiple factors, including the level of safety and clarity you need in your Git workflow. Each command has its strengths and preferred use cases.

git checkout is highly versatile and handles various operations in a Git workflow. Its flexibility is valuable when performing different tasks within the repository. However, it is also prone to ambiguity and potential data loss if not used correctly.

On the other hand, git switch was explicitly tailored for branch operations. Its priority is safety, which is achieved by reducing the risk of accidental data loss during branch switches. However, its limitation is the inability to handle commit checkouts directly. If you need to switch to specific commits directly, a better choice is git checkout.

Ultimately, understanding the strengths and weaknesses of each command allows you to choose the most suitable one based on your specific use case and workflow requirements.

Can You Use Git Checkout and Git Switch Interchangeably?

The two commands are somewhat interchangeable.

git switch is recommended for branch operations due to improved safety checks, while git checkout is a more robust and versatile tool for file and commit operations.

Nevertheless, it is possible to use them in the same workflow, but their purpose should be clarified. For example, your team can decide to use git switch for branch switching and git checkout for other operations, such as checking out a file, tag, or commit, or updating submodules.

Conclusion

This article has compared two essential Git commands, git switch and git checkout, and provided the advantages and disadvantages of each one. The easiest way to decide which one to use is to compare their functionalities, test them by following the examples in this article, and experiment with both.
