I am running openSUSE 12.1 x86_64 and was looking at what was running
with htop and saw the process owned by root using the command “-:0”
without the quotation marks. Does anybody know what this is. I did a
quick search on Google but did not find what I was looking for.
Thank you,
Eric
I would guess the X server. It modifies its first argument to be of the form -host:displaynumber. When host is contacted via a Unix socket rather than TCP/IP, then host is blank, so you get -:0.

could you take a screen shot of that, post it to paste.opensuse.org, and
fling the URL back to here please…
i ask, because i don’t have a running 12.1 to peek at…
my 11.4 shows an xorg process launched with a command line switch of “:0”
the entire line in htop is:
/usr/bin/xorg -br :0 vt7 -nolisten tcp - auth
/var/lib/xdm/authdir/authfiles/A:0-cTarec
could that be what you are seeing, but with an extra dash, as in ‘-:0’

Similar commands might help you narrow down what is happening on your system.

VERY cool, thanks…
but, tell me where that % comes from and what it means, please
i can guess it is the opposite of # and maybe the same as or similar
to $, but i have to wonder how i missed that fact…or is it something
‘new’?

Definitely not new - it’s the default prompt from the C-shell (csh).
Haven’t seen it in years - all my csh use went to tcsh (and thence to bash).
Sniff. Seeing ‘%’ prompts makes me nostalgic for ADM-3As and VT-100s.

ah! thanks…
i read about such but being a wimpy noob, it was just reading–having
only had the pleasure of bash in my slow transition from OS/2 beginning
about 1997/8, or so.

That’s just what I put in my prompt, instead of the path. I know where I am, so I don’t need that to be there.
Well, an xterm is a bit like a vt100. And the whole point of a desktop environment, is that you can open a bunch of xterms

I will have to remember those commands when I want to know what is
controlling a process.
Thank you,
