我对这个剧本有些麻烦

#! /bin/sh
case $1 in
        upssms)
                logger -t upssched-cmd "The UPS has been gone for 30 secs. Warn by sms..."
                /bin/echo "Power failed. System will hibernate soon..." | /usr/bin/curl "https://service.com/sendmsg=Failure!"
                ;;
        upsgone)
                logger -t upssched-cmd "The UPS has been gone for 2 and a half minutes. Hibernating..."
                #/usr/sbin/hibernate      # direct call to hibernate is not allowed by non-root
                /usr/sbin/upsmon -c fsd   # call a shutdown in NUT instead
                ;;
        ups-back-on-power)
                logger -t upssched-cmd "The UPS power has been restored."
                /bin/echo "Power restored." | /usr/bin/curl "https://service.com/sendmsg=Back!"
                ;;
        *)
                logger -t upssched-cmd "Unrecognized command: $1"
                ;;
esac

我无法弄清楚错误的位置，因为我没有收到通知。救命啊！

Bash变得超级敏感！双引号内的标记。我修改了URLS以使用感叹号的URL编码版本。每个ASCII表的十六进制代码21。 http://www.asciitable.com/

#! /bin/sh
# If your heart is set on using exclamations
# Use this syntax - "sendmsg=Failure"'!' 
case $1 in
    upssms)
            logger -t upssched-cmd "The UPS has been gone for 30 secs. Warn by sms..."
            /bin/echo "Power failed. System will hibernate soon..." | /usr/bin/curl "https://service.com/sendmsg=Failure%21"
            ;;
    upsgone)
            logger -t upssched-cmd "The UPS has been gone for 2 and a half minutes. Hibernating..."
            #/usr/sbin/hibernate      # direct call to hibernate is not allowed by non-root
            /usr/sbin/upsmon -c fsd   # call a shutdown in NUT instead
            ;;
    ups-back-on-power)
            logger -t upssched-cmd "The UPS power has been restored."
            /bin/echo "Power restored." | /usr/bin/curl "https://service.com/sendmsg=Back%21"
            ;;
    *)
            logger -t upssched-cmd "Unrecognized command: $1"
            ;;
esac

使用CURL的Bash脚本
