git-write-tree

Create a tree object from the current index

$ git write-tree

$ git write-tree --missing-ok

$ git write-tree --prefix [subdirectory]/

git write-tree [--missing-ok] [--prefix=]

--missing-ok
    Allow the command to succeed even if some objects referenced by the index are missing.

--prefix=
    Write a tree object that represents a subtree of the current index, rooted at the specified .

The git-write-tree command creates a tree object from the current staging area (index). This command essentially packages up the current state of your staged changes into a hierarchical tree structure that Git can track. It doesn't commit the changes; it only creates the tree object which can then be used by git-commit or other higher-level commands to construct a commit.

The command reads the index, which contains a snapshot of the files that are planned for the next commit. Each file in the index is represented as a blob object, and the command creates a tree object that represents the directory structure and the associated blob objects. The resulting tree object represents the state of your project at a specific point in time, based on what is currently staged.

This command is generally used internally by Git. Direct use is unusual but can be helpful for scripting or advanced use cases where you need precise control over the creation of tree objects.

Upon successful completion, git-write-tree prints the SHA-1 hash of the newly created tree object to standard output. This hash can then be used as a reference to the tree in subsequent Git operations.
