Wifi 断开时通知

我在终端中运行脚本，但有时 wifi 断开连接，脚本停止工作。我大部分时间都不在笔记本电脑旁，那么有没有办法让我在 wifi 断开连接时用声音通知我？

此外帕特里克·特伦丁的解决方案。如果您想要这种脚本，可以尝试它的 python 版本。两者都很好用。这里：

一个非常简单的实现这一目标的脚本可能如下：

#!/bin/bash

PERIOD=10       # s.
WARNING_TEXT="Warning: the connection to SKYNET was lost."
LANGUAGE="en"
ICON="notification-network-wireless-disconnected"

# conn_monitor.sh:
# polls the connection state after PERIOD seconds, and reads aloud a warning message
# in case there is no connection
#
# dependencies:
# - sudo apt-get install espeak binutils libmad libnotify-bin
# NOTES:
# - nm-tool has been replaced by nmcli in newer versions of ubuntu (>= 15.04),
#   see the output of `nmcli dev` to adapt this script to your needs.

function conn_monitor() {
    while true :
    do
        sleep ${PERIOD}
        mem_data=$(nm-tool | grep "State: connected")

        if [[ -z "${mem_data}" ]]; then
            notify-send "${WARNING_TEXT}" -i ${ICON} -u critical
            paplay /usr/share/sounds/freedesktop/stereo/suspend-error.oga
            espeak -a 200 -v ${LANGUAGE} "${WARNING_TEXT}"
        fi
    done
};

if [[ "$BASH_SOURCE" == "$0" ]]; then
    conn_monitor $@
else
    export -f conn_monitor
fi

然后可以添加一个名为的文件，conn_monitor.desktop内容~/.config/autostart如下：

[Desktop Entry]
Type=Application
Exec=..path..to..your..script..
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name=Conn Monitor
Comment=

其中您正确设置了脚本位置的路径。

我测试了脚本Ubuntu 14.04。
