Sudo bash in install service about nvoc_by_fullzero_community_release HOT 5 CLOSED

Not a good solution (I think variable substitution is made after). Prefer:
sudo bash -c 'cat > /etc/systemd/system/nvoc.service' << EOF ...

And brackets are useless {$HOME} -> $HOME.

Variables substitution is made while installing the service, ie while executing 'bash nvOC install-service'. What's the difference between the two approaches?

First just doesn't work. variables stay empty. In second version, substitution is done.

I can't reproduce your situation. I just mad this script write into ./test.txt instead of the actual nvoc.service file and this is what happened:

m1@m1-desktop:/nvOC-git$ bash nvOC install-service
m1@m1-desktop:/ nvOC install-service
Reinstalling nvOC service for /home/m1/nvOC-git
Setting ACL for 'nvoc' service user write access to NVOC path...
Done.\e[0m This service has autostart enabled.
m1@m1-desktop:/nvOC-git$ cat test.txt

As you can see variables substitution is working.

I'll now commit your alternative in any case, since it's working as well.
