Git - Staging area (or index) - Proposed next commit

About

The staging area is a tree file called index that stores information (file, directory, message, …) about the next commit.

The index is like a pre-commit.

The index holds a snapshot of the content of the working tree, and it is this snapshot that is taken as the contents of the next commit.

Thus after making any changes to the working directory, and before running the commit command, you must use the add command to add any new or modified files to the index (ie staging area).

Command

  • By default, the .git/index file
  • or the GIT_INDEX_FILE environment variable

To list the files the contents of the index with the stage information:

  • The mode of the file
  • The id of the object,
  • The stage of the file (in next commit or not)
  • and the pathname of the file
git ls-files --stage
