Unnamed command not found in "Interdiction, page 4"

Hello, I am very new to cyber security and do not fully understand everything. I am having a issue with the command “unname -a”, it keeps saying that command not found. The issue could possibly be that I have difficulty with locating bash on the desktop (I opened it by opening menu and typing “bash” in the search bar, then pressing enter.)
If you could help me resolve the issue that would be nice.

The command is uname -a

Wait. Did I make that mistake somehow… holy ■■■■ I spent a good 2 hours trying to solve this and it was just a simple spelling mistake? How did I miss this?
