git-checkout-index:tldr:9b814
The command "git checkout-index --all" is used to copy the contents of the current commit or the current working directory to the index (also known as the staging area) or to a specific directory on the file system.
Here's a breakdown of the command:
-
"git checkout-index" is the main command used to copy files from the repository to the working directory or to a specific space on the filesystem.
-
"--all" is an option that tells Git to copy all the files in the current commit or working directory to the index.
The "index" here refers to the staging area in Git, which is a space used to keep track of changes before committing them. By running this command, you are copying all the files from the current commit or working directory to the staging area, making them ready to be committed.
This command is useful when you want to copy the contents of the current commit to the working directory or to the index without changing branches or modifying the commit history. It can be helpful, for example, when you want to create a copy of the current state of your repository without committing it yet or when you want to remove the changes you made to the files in the working directory and revert them to the state of the latest commit.
