Subject: leaving old programs running

(This message is being sent to all CPSC 360 students)

I am definitely NOT a solaris sysadmin guru.  But it does appear that
it is possible to leave a program running for a considerable time on
a solaris system possibly even after you log out.  (Andrew are you
still logged in from yesterday??)

acad/cs360 ==> ps aux | grep asfowle

Leaving one process running on jmw (where I possess the power to
terminate,with extreme prejudice,any process) is not a big deal.

But back at the start of class someone expressed the opinion that
all of your processes were terminated when you log out.  If this is
not true (and I still don't know) it would be a big deal to have
a broken program leave HUNDREDS of processes running after the user
logged out!!! So lets be careful.

Depending upon your shell/environment you may have to use
ps -fed
to dump the process table.  Pipe it through grep to look for yourself
or a program name:
