[1]From bash to zsh on macOS:

    In anticipation of macOS 10.15 Catalina, I have changed my shell
    from bash to zsh. macOS 10.15 will use zsh as the new default, and I
    was pretty sure that things will break immediately unless I prepare
    - so I did prepare, and I found the transition very simple.

  (Via [2]Worklog of Christian Tietze)

  No. Just wrong.

  It is correct that the default shell for new accounts in the next major
  macOS release is [3]zsh. However, it does not mean current users need
  to switch. Apple is not forcing existing users to zsh. Unless you're
  installing from scratch and are not planning to use [4]MacPorts or
  [5]Homebrew to install the latest [6]bash for your shell ([7]the
  built-in bash is dangerously out of date and insecure), then …

  This

  Does

  Not

  Impact

  You

  Please don't confuse the issue for others.

  Switch if you want to switch. Follow your joy. I'm not going to tell
  you otherwise, though it is not a path I expect to walk in the near
  term. zsh is fine. I played with it several times. There is no
  compelling reason for me to switch.

  Here endeth the rant.
