Where is `npm link` registring commands on Ubuntu?

Background

I have an NodeJS oclif CLI named "mydemo" and ran npm link to register and execute the program's commands globally. After I ran npm unlink mydemo to unregister the command, when I type the program's name, I get the error below.

$ mydemo
bash: /home/eric/.nvm/versions/node/v15.8.0/bin/mydemo: No such file or directory

Expected output

$ mydemo
mydemo: command not found

Question

How does Linux still know to look in the ".nvm" directory for this command if I've unlinked it?

Attempts to figure it out

• Ran npm unlink
• Ran npm uninstall -g mydemo
• Ran which mydemo (no output)
• Searched for symlinks (maybe I didn't search the right place)

... it still searches that specific ".nvm" directory.

Environment

• Ubuntu 20
• nvm 0.37.2
• node v15.8.0
• "@oclif/dev-cli": "^1.26.0"

Nevermind. The command was cached in the shell session, possibly in the $PATH variable. It cleared in a new user session.
