how can I tell when my shared text file is in use?

[Guy Riddle]

The procedure I usually follow, when installing software where the text
file is likely to be in use is:

	mv /usr/lbin/vnews /usr/tmp/$$
	cp vnews /usr/lbin
	chown netnews /usr/lbin/vnews
	... etc.

So if the text files happen to be in use, they will sit in /usr/tmp
until the next reboot discards them.
