why doesn't john work on an unshadow file [duplicate]

Question

I was trying to unshadow my passwd and shadow file on the new version of john. However, every time I try to use john to decrypt the hash it throws an error.

Using default input encoding: UTF-8
No password hashes loaded (see FAQ)

But if I go to take a look at the file, I find my hashes there. Is this happening because the hash begins with root:$y$ instead of the normal hash identifiers?

Answer 1

I found an answer for this. The $y$ represents yescrypt which and be decrypted by john if the following command is used:

john --format=crypt filename
