使用的SYSTEMCTL状态grep的搜索结果为IF条件

Question

首先，感谢您就这个！

我在bash的脚本非常新手什么，我想实现的是：目前我有我的工作经常重新启动一些服务，我想创建一个纸条给automatise它，我设法创造的一切，但我想还创建有条件的地方，如果systemctl状态=无效然后回声“OK，很好，都好”所以让我们继续进行，但如果没有，那么回声“重新启动将重新atempted在10secs”;我使用grep来查找文本“活动：活动（运行）或”活动：从服务上的systemctl状态无效（死）（由bluetooth.service波纹管代表）：

#!/bin/bash
#Restarting  bluetooth.service

clear
active_stop="Active: stopped (dead)"    
echo  "This script will RESTART the following service: Bluetooth.Service"
echo -e  "State the REASON for the RESTART: " >> /home/sjadmin/SYS_RESTART/ARCHIVE/sysrestart.log
read -p  "Press ENTER to continue or CTRL + C to cancel"

sudo systemctl stop bluetooth.service |grep active IF [[grep -q=$active_stop]] 

then read -p  "Service STOPPED, please confirm status bellow, press ENTER to continue..."
else read -p "Action failed";

fi

sudo systemctl status bluetooth.service |grep status1="$(Active: active (running))" >> /home/sjadmin/SYS_RESTART/ARCHIVE/sysrestart.log

sudo systemctl status bluetooth.service |grep active

echo  "Service will be RESTARTED in 5 MINUTES, PLEASE DO NOT DISCONECT FROM THE SYSTEM..."

sleep 10s

sudo systemctl start bluetooth.service

read -p "Service RE-STARTED, please confirm status bellow, press ENTER to continue..."

sudo systemctl status bluetooth.service |grep active >>  /home/sjadmin/SYS_RESTART/ARCHIVE/sysrestart.log

sudo systemctl status bluetooth.service |grep active

echo  "System RESTARTED CORRECTLY, please find the log at the SYS_RESTART/ARCHIVE folder"

在此先感谢所有帮助和支持！ :)

我建议，而不是使用解析状态输出systemctl show <service-name> --no-page：

status="$(systemctl show bluetooth.service --no-page)"

status_text=$(echo "${status}" | grep 'StatusText=' | cut -f2 -d=)
if [ "${status_text}" == "Running" ]
then
    echo "It's running"
else
    echo "Not running"
fi

active_state=$(echo "${status}" | grep 'ActiveState=' | cut -f2 -d=)
if [ "${active_state}" == "active" ]
then
    echo "It's active"
else
    echo "Not active"
fi
