I recently did the command line lesson on configuring an environment, such that it sends a welcome message whenever a new terminal is opened. I tried to do this on my own computer, a MacBook running zsh, but it did not work.

Any thoughts on what I might be doing wrong? Is there a different command than echo in zsh as opposed to bash?
