ZSH is an extremely good replacement for bash and it helps in great productivity.
Setting up ZSH is extremely hard to do so since it does not have a compiled binary available.
It is widely used in the linux community.
I humbly request you to add it part of the modules.
I added a zsh module:
module load gcc/11.3.0 zsh/5.9
Try that out.
If you want to automate zsh setup when logging in, add the following to your
exec /spack/2206/apps/linux-centos7-x86_64_v3/gcc-11.3.0/zsh-5.9-eepz55r/bin/zsh -l
And you can comment out the bash stuff if you want.
