Git write-tree Quiz

Review

1. What does `git write-tree` serialize?

   write-tree creates tree objects from the current index.
2. What object does successful `git write-tree` print?

   The command prints the name of the new top-level tree object.
3. Why does an unresolved merge prevent ordinary `git write-tree`?

   An unmerged index contains conflict stages rather than one resolved entry per path.
4. What does `--prefix=sub/` write?

   The prefix selects the subtree represented by that index path.
5. What does `--missing-ok` change?

   It disables the object-existence validation; it does not create missing objects.
6. Which command reads tree information into the index?

   read-tree is the reverse direction: tree information into the index.
7. Which command is primarily used to inspect the tree produced by write-tree?

   ls-tree lists the entries of an existing tree object.
8. If the working tree changed after staging, what does write-tree record?

   write-tree consumes the index; update the index first if newer working-tree content should be represented.
9. What must be true before normal write-tree can serialize a merge result?

   The official command requires a fully merged index.
