What does git fsck stand for?

git, git-fsck

Solution

It stands for File System ChecK. The name is taken from the Unix `fsck` command, which is used to validate a file system.

While Git is not technically a file system, it can be used analogously and the command name is a metaphor on this.

Problem

What is the meaning in behind the `fsck` command name? The documentation of the command does not seem to mention what the name stands for.
