systemctl question

[Mike Wright]

Hi all,

While trying to get vncserver working I found this within

     /lib/systemd/system/vncserver@.service file.

         /usr/bin/vncserver %i

What is %i?

Can anybody explain from where this syntax derives?

TIA (and befuddled, meanwhile :),
Mike Wright

It appears the "@" allows the service to run multiple instances, which
I can see as a good thing for vnc. In order to start the service I
think you'll need to name your instance, i.e.:

systemctl start vncserver(a)&lt;my_instance_designator&gt;.service

and the "%i" will resolve to your instance designator.

Or that's what this link[1] said :)

However did you find that?  I do thank you for that bit of obscurity. 
Too bad it's not in the man page.

Thanks for finding that obscure reference. Pity it isn't in the man page where

mere mortals could find it. :-(
