Git checkout command is used to switch between different branches and to update the files in the working directory to match the versions stored in a specific branch or commit.
Here’s an example:
Suppose you are working on a branch called “feature-branch”, and you want to switch to the main branch. You can use the following command:
git checkout main
This command will switch you to the main branch. Now, let’s say you need to work on a specific commit in that branch. You can use the commit hash or ID to check out that version as follows:
git checkout 87a3cde
Here, 87a3cde is the commit ID you want to check out.
I hope that helps!
