Git - Tree Object

Table of Contents


In Git, a tree is an object that corresponds to file system directories in the git file system.

A single tree object contains:

  • one or more entries, each of which is the SHA-1 hash of a blob
  • or subtree with its associated mode, type, and filename.

A snapshots of a directory is a tree and every new snapshot is a new tree.


Most-recent tree with the master^{tree} syntax that specifies the tree object that is pointed to by the last commit on your master branch.

  • On linux bash
git cat-file -p master^{tree}
git cat-file -p master^^{tree}
  • On powershell, you need to quote it because of the {} characters.
git cat-file -p 'master^{tree}'
