Trees and Blobs

Now that we understand some of our plumbing equipment, let's get into the pipes. Here are some terms to know:

tree: git's way of storing a directory
blob: git's way of storing a file

Here's what I got when I inspected my last commit:

> git cat-file -p 5ba786fcc93e8092831c01e71444b9baa2228a4f

tree 4e507fdc6d9044ccd8a4a3061324c9f711c4667d
author ThePrimeagen <[email protected]> 1705891256 -0700
committer ThePrimeagen <[email protected]> 1705891256 -0700

A: add contents.md

Notice that we can see:

The tree object
The author
The committer
The commit message

However, we cannot see the contents of the contents.md file itself! That's because the blob object stores it.

Assignment

Use git cat-file -p again, but this time with the hash of the tree object instead of the commit hash. You should see a blob object with its own hash.
Use cat-file again, using the blob object's hash to view its contents.
Run that same command, but this time redirect the output to a temporary file: /tmp/blobfile.txt.

Run and submit the CLI tests.
