Creating and switching in one step in Git - Visual Walkthrough

Process Flow - Creating and switching in one step

Start on current branch

↓

Run git switch -c <new-branch>

↓

Create new branch named <new-branch>

↓

Switch HEAD to <new-branch>

↓

Now on new branch

↓

Done

This flow shows how git creates a new branch and switches to it immediately using one command.

Execution Sample

Git

git switch -c feature-x

Creates a new branch named 'feature-x' and switches to it in one step.

Process Table

Step	Command	Action	Result	Current Branch
1	git switch -c feature-x	Check if 'feature-x' exists	Does not exist	main
2	git switch -c feature-x	Create branch 'feature-x'	Branch created	main
3	git switch -c feature-x	Switch HEAD to 'feature-x'	Switched to new branch 'feature-x'	feature-x
4	-	End of command	Now working on 'feature-x'	feature-x

💡 New branch 'feature-x' created and switched to successfully.

Status Tracker

Variable	Start	After Step 2	After Step 3	Final
Current Branch	main	main	feature-x	feature-x
Branch 'feature-x' Exists?	No	Yes	Yes	Yes

Key Moments - 2 Insights

Why does the command create a new branch instead of switching to an existing one?

Because the '-c' option tells git to create a new branch. If the branch already existed, git would show an error. See execution_table step 1 and 2.

What happens if you omit '-c' and just run 'git switch feature-x'?

Git tries to switch to an existing branch named 'feature-x'. If it doesn't exist, it errors out. The '-c' option is needed to create and switch in one step.

Visual Quiz - 3 Questions

Look at the execution table, what is the current branch after step 3?

A main

B feature-x

C master

D develop

💡 Hint

Check the 'Current Branch' column in execution_table row for step 3.

At which step does git create the new branch?

A Step 3

B Step 1

C Step 2

D Step 4

💡 Hint

Look at the 'Action' and 'Result' columns in execution_table for branch creation.

If the branch 'feature-x' already existed, what would happen at step 2?

A Git shows an error and stops

B Git creates a new branch anyway

C Git switches to the existing branch without error

D Git deletes the existing branch and creates a new one

💡 Hint

Recall the explanation in key_moments about the '-c' option behavior.

Concept Snapshot

git switch -c <branch-name>
Creates a new branch and switches to it immediately.
If branch exists, command errors out.
Saves time vs separate create and switch commands.
Use to start work on a new feature branch quickly.

Full Transcript

This visual execution shows how the git command 'git switch -c feature-x' works step-by-step. First, git checks if the branch 'feature-x' exists. Since it does not, git creates the new branch. Then git switches the HEAD pointer to the new branch, making it the current working branch. The variable tracker shows the current branch changing from 'main' to 'feature-x'. Key moments clarify that the '-c' option means create and switch, and if the branch already exists, git will error. The quiz tests understanding of when the branch is created, what the current branch is after switching, and what happens if the branch exists already. This command is a shortcut to create and switch branches in one step, saving time and commands.
