运行 ruby 登录 xfce 时的脚本

Question

我正在使用 manjaro，我想在登录后运行一个 ruby 脚本。

这是我的脚本：


def get_line(filename, lineno)
  File.open(filename,'r') do |f|
     f.gets until f.lineno == lineno - 1
     f.gets
  end
end


filename = "list.md"
filepath = File.join(File.dirname(__FILE__), filename)

count = %x{cat #{filepath} | sed '/^\s*$/d' | wc -l }.to_i
random_element = rand((1..count))

line = get_line(filepath, random_element)

options = { :address              => "smtp.gmail.com",
            :port                 => 587,
            :user_name            => 'xxxx@gmail.com',
            :password             => 'xxxxx',
            :authentication       => 'plain',
            :enable_starttls_auto => true  }

Mail.defaults do
  delivery_method :smtp, options
end

Mail.deliver do
       to 'xxxxx@gmail.com'
       from 'xxxxxx@gmail.com'
  subject 'Test'
     body "#{line}"
end

我尝试了 /etc/profile.d、.bash_profile 并作为 /etc/systemd/system

的服务

[Unit]
Description=Example systemd service.

[Service]
Type=simple
ExecStart=/usr/bin/ruby /home/dnl/Documents/git/send_mail_reminders/send_mail.rb

[Install]
WantedBy=multi-user.target

我做了服务启动、状态、启用，然后重新启动。

服务状态输出

我的ruby代码有问题吗？

Answer 1

根据生成错误的行号，打开网络套接字时超时，因此当您的服务运行时网络似乎还没有准备好。尝试此 [Unit] 部分，以便服务将在网络初始化后启动：

[Unit]
Description=Example systemd service.
Requires=network-online.target
After=network-online.target
