If you use an apt-based distro, just copy-paste the script code into your server terminal, or use curl:
curl -fsSL https://gist.githubusercontent.com/pablopunk/a35b1b18aebc9db2427875ec395111c9/raw/0a4a38ad7661acc4ba43115da36c959e1fa70a43/a_better_linux_shell.sh | bash -s
For other distros, just manually install these: curl
, git
, zsh
and vim
and copy-paste everything after the apt setup.
