My memory is failing me, but I seem to recall that
here in Oz we had a
similar program, possibly written by Piers Lauder? Or IanJ?
It was called "ss" or something, for "system status", and I dimly
recall
modifying it (or suggesting same) to show the hostname.
BSD's systat is similar.
The current manpage says it was released in 4.3 BSD, but the copyright
notices in the code go back to 1980, with comments crediting "Bill Reeves
at Lucasfilm."
