systemd equivalent

[Bob Bernstein <poobah@ruptured-duck.com>]

I need to steel myself to using systemd commands. What 
would be the "systemd-correct" form of this:

$ ps ax | grep ssh

I use that to check for the existence (or, as the case 
may be)  demise) of an ssh tunnel I use for VNC. What 
should I use?


Thanks all,
