Does it say in any 3.1 note that zsh is going to be included?
zsh port doesn't (publicly) exist yet.
It's in the z/OS 3.1 announcement letter that was posted here last week
Might want to check the zopen install command for powerline.
I recommend installing the entire suite

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.

What version of bash are you using? 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".

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.

I am confused and am throwing out a Hail Mary for help. Here is the situation.
Two cloned LPARs. (same sysres and unix root file systems)
On system 1 - the /etc/profile has a PS1 of
export PS1="[\\u@\\H \\W \\@]\\$ "
On system 2 - the /etc/profile has a PS1 of
export PS1="[\\u@\\H \\W \\@]\\$ "
Why YES they do look the same... at least they do to me.
-=-=-=
The results however are very different.
On system one the displayed PS1 is
[TECH905@jismvs_test ~ 11:26 AM]$
On system two the displayed PS1 is
[\u@\H \W \@]$
-=-=-=-=
I am using the same SHELL program in my environment. (/usr/bin/bash)
Anybody have any ideas why the two different LPARs are reading the same string
but interpreting it in two different ways?
My suspect is some dark secret settings in the Unix file system. Total Guess
