Question

我希望在网络环境发生变化时，使用不同的配置运行wtome wm。因此我在网络管理器调度程序中编写了一个脚本，以便在网络环境发生变化时执行脚本;

#!/bin/bash
# Restart awesome through awesome-client

USER=dreamingo

awesome_restart(){
    /bin/su $USER -c "echo 'local awful = require (\"awful\"); return awful.util.restart()' | awesome-client"
}

#To check the cable insert or not
wire_insert_state=$(cat /sys/class/net/eth0/carrier)
#Check which config the current awesome taking(wired or wireless)
current_config=$(cat ~/.config/awesome/flag)

# if [[ $wire_insert_state = 1 ]] && [[ $current_config == "wireless" ]];then
if [[ $wire_insert_state = 1 ]];then
    cp /home/dreamingo/.config/awesome/rc.lua.wire /home/dreamingo/.config/awesome/rc.lua
    echo wired > ~/.config/awesome/flag
    awesome_restart

# elif [[ $wire_insert_state = 0 ]] && [[ $current_config == "wired" ]];then
elif [[ $wire_insert_state = 0 ]];then
    cp /home/dreamingo/.config/awesome/rc.lua.wireless /home/dreamingo/.config/awesome/rc.lua
    echo wireless > ~/.config/awesome/flag
    awesome_restart
fi

然而，这个脚本确实在环境发生变化时运行，但很棒的wm不会重新启动。

我认为这是脚本由root执行的原因，因此我使用以下命令：

/bin/su $USER -c "echo 'local awful = require (\"awful\"); return awful.util.restart()' | awesome-client"

当我su到root时，这个命令会起作用（重启awesome wm）;但是，当我使用时：

sudo ./02check_wireless    #02check_wireless was the name of the script

运行脚本，脚本无法重启wm;但是当我把它作为当前用户（dreamingo）运行时，它可以工作;

此外，无论上述结果（成功与否），脚本都会输出：

Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.naquadah.awesome.awful was not provided by any .service files

我认为失败者也试图重新启动真棒，但覆盖或阻止它......

当我以root身份运行

时，这个变种对我来说非常好用3.5.5

#!/bin/bash
# Restart awesome through awesome-client

USER=my_username_here

awesome_restart(){
    /bin/su $USER -c "echo 'awesome.restart()' | awesome-client"
}

awesome_restart
