It's pretty rare. It is assumed that Unix uses can type " | less" if they want to view the output of a program with a pager. That's simpler and faster than spending time to try to figure out if and how you tell some particular application to invoke a pager for you. > I could only find: > > mysql --pager CMD > > which seems sensible but nothing like an industry standard. > > Personally, I wouldn't bother with builtin paging. I agree completely. Builtin paging is pretty much pointless -- but if you _are_ going to do, make it something that you invoke with a command line option. -- Grant -- https://mail.python.org/mailman/listinfo/python-list
