Subject: Re: login shells

In current UNIX there is a mechanism like in 10th edition UNIX, although
it's hidden. "who am i" in its long format tells you from where you have
logged onto a machine.

I use this feature to set the DISPLAY env. variable in my X11 environment.
It works on SunOS 4.*, Ultrix 4*, AIX 3.1*, and A/UX 2.* and maybe others
I don't have access to.

One could easily include a few lines which check for that
(hostname != "entry_in_etc_utmp").
