something like motd question

[bob shaw]

This is probably a very "basic" question .

What I am looking for is something like /etc/motd.

I would like to have a file that is read when a user logs in 
*IF* this file has been updated since it was last read by this
user.  This file would contain specific system  news info, etc and 
would constantly be changed by the sys_admin.

I know that /bin/login is first consulted when you login so something
like this is probably what I am looking for.

My particular system is a Sun SS1 or SS2. 

Any comments appreciated.

Thanks in advance.
