Git Checkout Fast - Shell/Bash

As a programmer, you are probably familiar with Git - a powerful version control tool used by developers to manage their code repositories. One of the most commonly used Git commands is git checkout, which allows you to switch from one branch to another, or to revert your code to a previous commit.

However, it can sometimes take a while for Git to switch branches or revert your code, especially if your repository is large or your computer is slow. This is where the --fast option comes in - it allows you to perform the checkout or revert operation much more quickly.

Usage

To use git checkout fast, simply add the --fast option to your checkout or revert command, like so:

git checkout --fast branch_name

or

git revert --fast commit_hash

This will perform the operation more quickly than the standard git checkout or git revert commands.

How It Works

When you use the --fast option with git checkout, Git skips some of its usual checks and optimizations, which allows the operation to complete more quickly. Specifically, it skips the following steps:

• Checking whether your working directory is clean (i.e. has no uncommitted changes)
• Updating the index with the new branch or commit
• Updating the files in your working directory with the new branch or commit

This means that git checkout --fast can be significantly faster than the standard git checkout command, especially if you have a large repository or a slow computer.

Conclusion

In conclusion, git checkout --fast is a powerful option for programmers who want to switch branches or revert code quickly and efficiently. By skipping some of Git's usual checks and optimizations, it allows these operations to be performed much more quickly, even on large repositories or slow computers. So next time you need to switch branches or revert code, give git checkout --fast a try!
