[chef] Re: Using not_if in bash block still causes file to be downloaded

[Matt Ray < >]

Perhaps using remote_file might be cleaner?

  remote_file "/tmp/hubot-#{version}.tar.gz" do
    source  
"https://github.com/downloads/github/hubot/hubot-#{version}.tar.gz";
    action :create_if_missing
  end

  execute "tar -xzf /tmp/hubot-#{version}.tar.gz" do
    cwd "/tmp"
    subscribes :run, resources(:remote_file =>
"/tmp/hubot-#{version}.tar.gz"), :immediately
    action :nothing
  end

Thanks,
