Is it possible to kill another user's process in plan9?
Specifically I've been messing about with tftpd, which sets itself up
as user 'none' - if I want to stop the tftp server, how do I do that?
Thanks,
Pete

If you're the host owner, you can:
Kill tftpd | rc
(See rc scripts kill and Kill)

Thanks, Skip.
I thought that ought to work, however 'kill tftpd' doesn't give any
output. (I can kill other processes)
I think maybe I have misunderstood the host owner part. If I do a
plain install (of 9front, actually) from the CD and log in as glenda,
am I not the host owner?
Thanks,
Pete

lower case kill restricts the list to processes of the invoking user
initial cap Kill doesn't do that.
for lower case kill, you can @{rfork n; echo -n none >/tmp/none && bind
/tmp/none /dev/user && kill tftpd}
you wouldn't normally of course but aspects of that command might be
instructive

Apologies both - didn't read Skip's answer properly. I saw kill where
I should have seen Kill.
