Install agnoster theme in zsh in docker from vscode console.

   # save current zshrc
   mv ~/.zshrc ~/.zshrc.bak
   
   sudo sh -c "$(wget -O- https://raw.githubusercontent.com/deluan/zsh-in-docker/master/zsh-in-docker.sh)" -- \
       -t agnoster
   
   # remove newly created zshrc
   rm -f ~/.zshrc
   # restore saved zshrc
   mv ~/.zshrc.bak ~/.zshrc
   # update theme
   sed -i '/^ZSH_THEME/c\ZSH_THEME="agnoster"' ~/.zshrc
