aria2.service
设置使用 systemd 启动 aria2 的服务文件 aria2.service：
[Unit]
Description=Start aria2 daemon
[Service]
ExecStart=/usr/bin/aria2c --conf-path=/home/poplar/bin/aria2/aria2.conf
Type=simple
WorkingDirectory=/home/poplar/bin/aria2
[Install]
WantedBy=default.target
index.html
启动服务
使用 ~/bin/command/aria2-m 启动服务：
#!/bin/sh
