The who (or w, or finger) command shows that I'm still logged into ttyp5,
even though I have rebooted the <xxx> box many times since. Does this mean
the corresponding entry in /var/run/utmp is wrong and shouldn't be there, or is there
still some process attached to ttyp5?
ouput of w:
USER TTY FROM LOGIN@ IDLE WHAT
mexas p4 <xxx> 1:32pm - w
mexas p5 <xxx>:0. 26Jan09 21days -
ps ax | grep ttyp5
shows no process
Looking at w(1) man page it seems that "-" in WHAT can be an indication
that the process failed but not cleanly and that there could be some forked
sub-process still alive. Does this make sense? Which other commands I can use
to see what's going on?
many thanks
anton
