git-cat-file
Display content or metadata of repository objects
TLDR
SYNOPSIS
git cat-file [options] object
DESCRIPTION
git cat-file provides direct access to Git's object database, allowing inspection of blobs, trees, commits, and tags. This low-level plumbing command reveals the internal structure of Git's content-addressable storage system.The command operates on object hashes (SHA-1 or SHA-256) and can display object type, size, or pretty-printed content. It's essential for debugging repository corruption, understanding Git internals, and forensic analysis of repository history.Common use cases include examining specific versions of files without checking them out, inspecting tree structures to understand directory layouts at specific commits, and validating object integrity. The -p flag pretty-prints objects in human-readable format, while -t and -s provide metadata without full content extraction.
