git-init: Initialize a repository using SHA256 for object hashes (requires Git version 2.29+).

$ git init --object-format=${sha256}

try on your machine

The command git init --object-format=${sha256} is used to initialize a new Git repository with a specific object format for storing its data.

In Git, an object format determines how the data of commits, trees, and blobs (files) are stored internally. By default, Git uses the SHA-1 (Secure Hash Algorithm 1) for generating object IDs, but this command allows you to specify a different object format, in this case, the SHA-256 (Secure Hash Algorithm 256).

The ${sha256} is a placeholder that gets replaced with the actual value by the shell or command-line interpreter. It represents the SHA-256 object format.

When you run this command, Git will create an empty repository and configure it to use the specified SHA-256 object format for all the objects it stores. This can be useful for improved security and collision resistance as the SHA-256 algorithm is considered stronger and less prone to collisions than SHA-1.
