I'm having an issue on 4.2 lab with what I thought would be a simple example for setting up a service with systemd

I'm running CentOS Linux release 7.3.1611 (Core) 

[student@dolphin ~]$ sudo cat /etc/systemd/system/fake2.service

[Unit]

Description=fake2

After=network.target

[Service]

ExecStart=/bin/sh -c ’/bin/echo I am starting the fake2 service ; /bin/sleep 30’

ExecStop=/bin/echo I am stopping the fake2 service

[Install]

WantedBy=multi-user.target

student@dolphin ~]$ sudo systemctl start fake2.service

Failed to start fake2.service: Unit is not loaded properly: Invalid argument.

See system logs and 'systemctl status fake2.service' for details.

[student@dolphin ~]$ sudo systemctl -l status fake2.service

● fake2.service - fake2

    Hey I ran the fake2.service configuration you posted (copy and pasted from above) and got a different error. I had to replace the single quotes around the Execstart parameters surrounding the echo command.

    I made the following change:

    OLD

    [Unit]

    Description=fake2

    After=network.target

    [Service]

    ExecStart=/bin/sh -c ’/bin/echo I am starting the fake2 service ; /bin/sleep 30’

    ExecStop=/bin/echo I am stopping the fake2 service

    [Install]

    WantedBy=multi-user.target

    NEW

    [Unit]

    Description=fake2

    After=network.target

    [Service]

    ExecStart=/bin/sh -c '/bin/echo I am starting the fake2 service ; /bin/sleep 30'

    ExecStop=/bin/echo I am stopping the fake2 service

    [Install]

    WantedBy=multi-user.target

    I don't know if it will resolve your issue. I hope this helps.

    Hi,

    That's weird; so, you replaced the single quotes by hand, right? Did you copy and paste the command from the pdf file? There may be something with the formatting.

    Hey,

    It is weird; by hand? As opposed to using sed or something else?

    I didn't look at the pdf. I just read rcmills post then copied and pasted the configuration for their service. I assumed that rcmills hand wrote the configuration since he/she also used the name 'fake2' instead of 'fake_service' (I think thats what the pdf used).. but they could have pulled it from the pdf themself and pasted it into an editor that altered the quotes too.

    Regardless, quotes are not used anywhere else in the configuration so I also assumed they used an editor other than vi or emacs--- likely an ascii code difference between open/closed quotes and straight quotes? I didn't look into it any further. Once I ran the service I just looked at the log and changed the line; it worked.

    Whoops- streamline thinking a bit. I'll look at the pdf later and see if there are any issues on my system similar to this problem.

    cutting and pasting from pdf's or html often screws up single quotes fro some reason
