linux – systemctl status显示inactive dead

[Unit]
Description=NandaGopal
Documentation=https://google.com
After=multi-user.target

[service]
Type=forking  
RemainAfterExit=yes
ExecStart=/usr/bin/Hello.sh &

[Install]
requiredBy = multi-user.target

这是我的sHell脚本.

#!/usr/bin/env bash

source /etc/profile
a=0
while [ $a -lt 10 ]
do
   echo $a >> /var/log//t.txt
        a=`expr $a + 1`
done

由于某种原因,服务没有出现,systemctl显示以下输出.

root@TARGET:~ >systemctl status -l Hello
* Hello.service - NandaGopal
   Loaded: loaded (/usr/lib/systemd/system/Hello.service; disabled; vendor     preset: enabled)
   Active: inactive (dead)

一直想弄清楚过去两天出了什么问题.
有人可以帮我吗？

问候,
