Git: Mastering Version Control

Writing a tree object to the database

Now, we have manually created objects in the Git database, but as nothing point to these objects, we have to remember them by their SHA-1 identifier. Furthermore, only the content of the files is stored in the database, so we learn to create a tree object that will refer to the blobs created.

Getting ready

We'll use the same repository of the last examples with the objects we created in the database.

How to do it...

$ git update-index --add --cacheinfo 100644 \

$ git write-tree
4c4493f8029d491d280695e263e24772ab6962ce

We can update ...
