...assuming you can work out what the service name is.  The CLI args
don't necessarially map to anything sensible, nor are they inherently
discoverable.  I've got a number of systems with the Cygwin utilities
installed (ergo:  remote ssh), and it's *still* a PITA trying to figure
out how to nudge the 'Doze side of things.

Contrast with the GNU/Linux side:  your services all live under
/etc/inet.d, as filenames (assuming SysV init, and IMVAO, Berkeley-style
init sucks rocks through a rusty straw...).  You can figure out WTF is
what, trivially.  'Doze just Gets In The Way.


...example.  Today, it was easier to add a 'Software' Samba share to
Apache as an aliased path, than to try to figure out how to get SMB
fileshare working under remote ssh sessions.  Rolling out SP2 <groan>.

Once I'd tweaked that (30 seconds), run a shell loop (for server in
<list> do ssh $server wget <url>; done).  Which took ~100 minutes to
run, but I wasn't there watching fscking pages float between two icons
(maddening, I tell, you, maddening).

...or two:  ps aux ;-)

...but still: the ability to identify processes and filter through
process lists (grep, awk, sort...) is *very* damned useful.

 
Peace.
