What does git fsck stand for?

Question

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.

Answer 1

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.

Answer 2

It was first called:

• fsck-cached (git 0.99), to check the repository for errors
• then fsck-objects (git 0.99.8), in order to report what exactly is wrong with the object, instead of an ambiguous 'bad sha1 file'.
• and finally git fsck (git 1.5.0, January 2007)

It reflects that Git was initially built as a file system, with a graph of nodes and git fsck is presented in this GitHub Training as a file system check which verifies integrity and finds corrupt objects.
