Question

我试图在启动时找到一种在Ubuntu 16.04上禁用蓝牙的方法，我在网上遇到的一种方法就是使用systemd

基本上

首先，停止服务：

sudo systemctl stop bluetooth.service

然后禁用它：

sudo systemctl disable bluetooth.service

检查：

sudo systemctl status bluetooth.service

https://askubuntu.com/questions/744640/best-way-to-deactivate-bluetooth-on-system-startup-with-systemd-and-not-upstar

但是每次我重新启动它都会重新启动，我无法在网上发现任何人抱怨systemd disable命令不像我的情况那样工作

即使在ubuntu wiki上它也说它应该可以解决我做错了什么？

这是我运行这些命令时的输出

Answer 1

也许服务是由依赖项启动的。您可以尝试third level of "off" with systemd，称为＆＃34;屏蔽＆＃34;：

systemctl mask bluetooth.service

一旦屏蔽，即使手动也无法启动服务。你可以揭开＆＃39;它以后。

Answer 2

在这里，您可以创建一个脚本，该脚本将在启动时运行并执行一项操作以终止蓝牙服务，如下所示（我使用nano，请随时使用任何其他文本编辑器）：

步骤1：导航到文件夹

cd /etc/systemd/system/

步骤2：：首先创建一个脚本，该脚本一旦运行便会终止蓝牙服务：

nano bluetoothkill.sh

步骤3：输入以下代码，保存并退出：

#!/bin/bash
rfkill block bluetooth
exit 0

步骤4：在同一文件夹/ etc / systemd / system /中创建foo.service文件：

nano foo.service

步骤5：输入以下代码，保存并退出：

[Unit]
Details=Additional startup scripts
After=network.target

[Service]
ExecStart=/etc/systemd/system/bluetoothkill.sh

[Install]
WantedBy=default.target

步骤6：在终端中运行以下命令：

sudo chmod 744 bluetoothkill.sh

步骤7：在终端中运行以下命令：

sudo systemctl start foo.service

步骤8：重新启动计算机，在下次启动时，您会注意到默认情况下在启动时不再启用蓝牙服务。您仍然可以随时在设置中或终端运行时启用它，而不会出现任何错误。

如果要在启动时添加更多脚本，则始终可以编辑foo.service文件，并在[Service]括号下添加其他行以在启动时运行其他脚本，例如： < / p>

ExecStart=/full-script-filepath/newscript.sh

systemctl disable name.service在重启后不会保留
