I tried to edit a service file in /etc/systemd/system/aria2.service [Unit] Description=start aria2 Wants=network.target Before=network.target [Service] Type=oneshot ExecStart=/usr/bin/aria2c --enable-rpc --rpc-listen-all=true --rpc-allow-origin-all -c -D [Install] WantedBy=multi-user.target Then run "systemctl enable aria2" & "systemctl start" and there is no error. But I can't grep 'aria2c' in process list after reboot. Who can give me a sample service file for it? Thanks
