NAME
git-write-tree - Create a tree object from the current index
SYNOPSIS
git write-tree [--missing-ok] [--prefix=<prefix>/]
DESCRIPTION
Creates a tree object using the current index. The name of the new tree object is printed to standard
output.
The index must be in a fully merged state.
Conceptually, git write-tree sync()s the current index contents into a set of tree files. In order to
have that match what is actually in your directory right now, you need to have done a git update-index
phase before you did the git write-tree.
OPTIONS
--missing-ok
Normally git write-tree ensures that the objects referenced by the directory exist in the object
database. This option disables this check.
--prefix=<prefix>/
Writes a tree object that represents a subdirectory <prefix>. This can be used to write the tree
object for a subproject that is in the named subdirectory.
