linux - Chef 多行命令

Question

我正在尝试在 Chef 中编写一个菜谱，但我一直不知道如何在 Linux 中的命令行中执行多行执行。首先是配方，接下来是我收到的错误输出。

node['freeswitch']['source']['dependencies'].each { |d| package d }

execute "apt_update" do
  command "wget -O - https://files.freeswitch.org/repo/deb/debian/freeswitch_archive_g0.pub | apt-key add -&&"
    "echo "deb http://files.freeswitch.org/repo/deb/freeswitch-1.6/ jessie main" > /etc/apt/sources.list.d/freeswitch.list &&"
    "apt-get update &&"
    "apt-get install -y --force-yes freeswitch-video-deps-most &&"

    # because we're in a branch that will go through many rebases it's
    # better to set this one, or you'll get CONFLICTS when pulling (update)
    git config --global pull.rebase true
end

下面是错误输出

Answer 1

&& 是 shell 的逻辑 and 运算符。您可以在 shell 中显式启动该命令，例如:

execute 'Execute a shell' do
    command "bash -c 'cmd1 && cmd2 && ..'"
end

或者您使用bash resource :

bash 'Execute bash script' do
    code <<-EOH
    cmd1 \
    && cmd2 \
    && ... 
    EOH
end
