While, IMHO, zsh should have been included in MVS/ESA SP V4.3 OpenEdition, I don't see it killing bash, due to compatibility.
I'm feeling a bit puzzled here! Bash doesn't come pre-installed with z/OS; rather, it's a tool ported by Rocket, so there shouldn't be any compatibility problems, right? If IBM decides to include zsh, which is considered superior to bash, this could be a game-changer.
Once IBM introduced their Python SDK for z/OS, Rocket's Python started struggling and eventually became obsolete.
It's perfectly fine to skip commenting on every discussion, especially when it's not within your field of expertise.

Rocket software's port or IBM z/OS Open Tools? Irrespective, bash is an enhanced ASCII application so make sure you have the following environment variables set in your profile login scripts by entering "env | sort" from the shell command line. _BPXK_AUTOCVT=ON _CEE_RUNOPTS=FILETAG(AUTOCVT,AUTOTAG) TERMTHDACT(UADUMP) ABTERMENC(ABEND) _TAG_REDIR_ERR=txt _TAG_REDIR_IN=txt _TAG_REDIR_OUT=txt Incidentally, I noticed that IBM are shipping zsh as part of z/OS 3.1 so bye, bye bash. I've being using zsh for years and it turbo charges the shell. For example, there are open source themes such as oh-my-zsh and powerline10k. The powerline customizes PS1 with fancy glyphs. The current Git branch, commits and other information is shown. It's next level to the dull one your using :). Also, there is zsh-autosuggestions which recalls previous commands for auto completion. oh-my-zsh also provides a plugin for git command completion and other super cool command completions that make using the shell as easy as an IDE. https://github.com/ohmyzsh/ohmyzsh/tree/master https://github.com/romkatv/powerlevel10k https://github.com/zsh-users/zsh-autosuggestions To enable the cool glyphs you will need to install Nerd fonts and configure your terminal emulator. If you're a Windows user and using PuTTY I recommend switching to Windows Terminial (preferably with WSL2) which has tabs, tiled windows and is just miles better. If you're on a Mac like me it's easy to configure Termimal, iTerm2 or whatever emulator you use. Same with Linux desktops. On z/OS "export TERM=xterm-256color" In the meantime, there is a port of powerline-go as part of the Z/OS Open Tools project. If you have downloaded the installer you can install it simply by running "zopen install powerlinegoport". https://github.com/justjanne/powerline-go # instructions how to configure it with bash *Z Shell (Zsh) on z/OS* The Z Shell (Zsh), specifically Zsh 5.8.1, has been ported and made available on z/OS 3.1. Zsh is a UNIX command interpreter that is used as an interactive login shell and as a shell script command processor. It has command-line editing, built-in spelling correction, programmable command completion, shell functions (with autoloading), a history mechanism, and a host of other features. With the extensibility, rich customization, and advanced features, Zsh provides a modern and powerful shell on z/OS. It is designed to accelerate users' daily work and have consistent behavior with other open platforms.
