If you're like me and still rely on the trusty git checkout for a variety of tasks—like switching branches, restoring files, and checking out commits—then you're in for a treat. The Git community has made things easier by introducing two new commands to split the workload: git switch and git restore.
These new commands were created to reduce the overload on git checkout and make Git a bit more intuitive, especially for developers who sometimes found it confusing. Let's break it down!
What git checkout used to do
The git checkout command was a Swiss Army knife in Git. It handled several different jobs, which could sometimes be confusing. With git checkout, you could:
- Switching branches:
git checkout <branch-name>
- Create a new branch and switch to it:
git checkout -b <new-branch-name>
## or create a branch from a specific commit
git checkout -b <new-branch-name> <commit-hash>
- Restoring files from the stage area Files that were modified and added to staging area can be brought back to last
git checkout <file>
- Restoring files from specific commit
git checkout <commit-hash> --file
- Checking out the code to a specific commit or tag:
It is as well called
detached HEAD, because theHEADpointer will point to a specific commit instead of the latst commit in the current branch:
git checkout (<commit-hash> | <tag-name>)
Why checkout was so overloaded
While all of these actions are useful, bundling them into one command could cause confusion, especially for newer users. You might ask, "Why does git checkout work in some situations and not others?" For instance, sometimes it works with staged files, sometimes with uncommitted changes, and other times it doesn't unless you commit first.
Because git checkout had to handle so many different tasks, the Git community decided to split its functionality. The command still works for backward compatibility, but now we have two specialized commands that simplify common tasks: git switch and git restore.
How to simplify your Git workflow
With Git 2.23, two new commands were introduced to ease the confusion: git switch for handling branches and git restore for managing files. These commands break down checkout's responsibilities and make Git operations clearer.
git switch
git switch is a command for switching branches.
So you have a command to switch to another branch
git switch <branch-name>
Or create a new branch from existing status
git switch -c <new-branch-name>
git restore
git restore is focusing on restoing files from specific commit, or disregard the changes in staging, or working area.
restore will restore the files from HEAD content, but without touching the index/stage area, but you can override that as we will describe down:
git restore <file>
# or restore all files from HEAD content without touching index/stage area
# to compare to checkout, which revert both working tree and stage area
git restore .
# to revert the changes in index/stage area only use the following override argument
git restore . --staged
# to revert both working tree and stage area use
git restore --source . --staged --worktree # this similar to git checkout .
Or you can restore to a specific commit
git restore --source <commit-hash> <file>
Wrapping up
While git checkout still works, switching to the new commands can make you Git workflow more intutive and less confusion. Branches, files, and commits are all just pointers in your Git history, but by using these specialized commands, you’ll reduce the mental load and avoid mistakes.
Take a few minutes to familiarize yourself with these new commands—you’ll be glad you did!
