The git diff-files
command is used to show the differences between the files in the working tree and the index (also known as the staging area) of a Git repository.
When you make changes to files in your working tree (i.e., the files on your local machine), Git provides a way to track these changes before committing them to the repository. This tracking is done through the index, which acts as a staging area where you can add, remove, or modify files before committing the changes.
The git diff-files
command compares the current state of the files in the working tree with the version of those files in the index. It displays the differences between these two versions, providing you with a summary of the changes you have made.
The output of the git diff-files
command shows the file names along with a series of symbols indicating the type of changes made to each file. These symbols typically represent additions (+), deletions (-), or modifications (M) in the file content.
This command is useful when you want to see the differences between the changes you have made in the working tree and the staged changes in the index. It helps to review your modifications before committing them, allowing you to verify and potentially make further adjustments if needed.
