Install zsh without root

install_zsh.sh

#!/bin/bash

set -e

# OPTIONAL: zsh will not install without ncurses. IF your machine doesn't have ncurses, you need to install it first.

This script more or less worked. My group has multiple machines with different configurations, however for all the machines the $HOME directory is the same. oh-my-zsh works perfectly fine when I ssh to one of the inferior machine, but when I ssh to one of the powerful machines for actual computation the following error occurs:

Do you have any solution for this?

Sorry I don't know what causes this :(

Thanks for the script! Works like a charm :)

Works perfectly, thanks!

This is not a promotion or spam, but for those people who cannot run oh-my-zsh due to some limitations and are using oh-my-bash but facing sluggish performance. I highly suggest all of them to watch this video and setup all the plugins independent of oh-my-zsh. Works flawlessly!
