• install zsh

  • MacOS (it's there and OK)
  • CentOS, RHEL, fedora: sudo install -y zsh
  • Debian, Ubuntu, raspbian: sudo apt install -y zsh
  • Windows? =Y You're kidding, use WSL2

• change your login shell like: usermod -s /bin/zsh $USER

• install ohmyz.sh: sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

• create a ~/.zshrc with the following content:

  ZSH_DISABLE_COMPFIX=true
  export ZSH="$HOME/.oh-my-zsh"
  ZSH_THEME="agnoster"

  export KUBE_PS1_SYMBOL_USE_IMG=true
  export KUBE_PS1_BG_COLOR=black
  export KUBE_PS1_SYMBOL_COLOR=red
  export KUBE_PS1_CTX_COLOR=blue
  
  function get_cluster_short() {
   echo "$1" | sed 's&.*/api-\([^-]*\)-.*:6443/\(.*\)&\1/\2&'
  }
  KUBE_PS1_CLUSTER_FUNCTION=get_cluster_short
  if [[ -n $TERM_PROGRAM ]]; then
    #we're on a macos

  else
    # we're everywhere else
    plugins=(ansible bundler git kubectl oc python ruby tmux themes kube-ps1)
  fi
  source $ZSH/oh-my-zsh.sh
  if [[ -n $SSH_CONNECTION ]]; then
    export EDITOR='emacs -nw'

    # we're everywhere else
    export EDITOR=vi
  fi
  if command -v emacs &> /dev/null
  then
    export EDITOR='emacs -nw'
    alias emacs='emacs -nw'

  export PATH=$PATH:$HOME/go/bin
  test -e "${HOME}/.iterm2_shell_integration.zsh" && source "${HOME}/.iterm2_shell_integration.zsh"
  test -e "${HOME}/.zshrc_local" && source "${HOME}/.zshrc_local"
