missing '=' etcd when defining service file

Question

I'm struggling while following Kelsey Hightower's "Kubernetes the Hard Way" tutorial. I've gone off script, because I'm trying to bootstrap k8s on a local server.

I've got the point where I'm bootstrapping etcd, however, when I'm creating the service I'm getting an error:

Failed to start etcd.service: Unit is not loaded properly: Bad message.
See system logs and 'systemctl status etcd.service' for details.

Checking the logs and I get:

Jun 21 20:16:49 controller-0 systemd[1]: [/etc/systemd/system/etcd.service:9] Missing '='.
Jun 21 20:16:49 controller-0 systemd[1]: [/etc/systemd/system/etcd.service:9] Missing '='.
Jun 21 20:17:25 controller-0 systemd[1]: [/etc/systemd/system/etcd.service:9] Missing '='.

Here's the etcd.service file:

[Unit]
Description=etcd service
Documentation=https://github.com/coreos/etcd

[Service]
User=etcd
Type=notify
ExecStart=/usr/local/bin/etcd \\
 --name ${ETCD_NAME} \\
 --data-dir /var/lib/etcd \\

Are you sure that is your unit file? Some lines appear to be missing, and there appear to be extra characters at the end of some lines. — Michael Hampton, Jun 22 '19 at 03:59
you're right, I missed the first line which is [Unit]. I added it. The \\ are because the one line is extremely long — Baron, Jun 22 '19 at 05:15

The answer was pointed out by @Michael Hampton. The two backslashes were because the code was supposed to be written from the terminal (in the guide). In the etcd.service file, lines should be broken with a single .

[Unit]
Description=etcd service
Documentation=https://github.com/coreos/etcd

User=etcd
Type=notify
