Re: where are docs for "ex"

[lark@world.std.com (Lar Kaufman)]

ex in most implementations is a mode of vi; check the documentation for
your vi implementation.  If you have a complete manpage system, you can
search for such "hidden" documentation by invoking (in your case) 
   man -k vi
where the string following the -k flag is a keyword (or a phrase in quotes)
to search for, taken from a table of the summary lines of the manpages.  
However, in many Linux distributions, this table will not have been built

makewhatis command.

For more info on getting the most from the venerable textual online help
system, man, enter "man man".  Note in particular the $PAGER variable 
which you can set to a favored screen browser in your user environment.
(I set $PAGER=less.)
