The bash shell in macos Catalina has been demoted to the subs bench with the newer zsh shell is now the default shell in use by the new operating system. Also known as the Z shell, it has been around a while, since 1990 (bash was 1988), it is still a Unix based shell and should be easily transitioned to from the old bash one as they share a common foundation.

Newer versions are licensed under the GPLv3 license, while Apple still distributes a version. I am trying to write a script to export all the system-roots-certificates from Keychain Access - System Roots - Certificates to a path as cert.pem file. I am trying hard to wrap my head around zsh 'upgrade' from bash in macOS Catalina. Most of the things are great, actually. However, I cannot figure out why I am experiencing difficulties.
The Bash shell will ultimately be dropped from the macos core.
