From dd1938e48f5b91b5383e0f2add96bf23a9d226be Mon Sep 17 00:00:00 2001 From: Mats O Jansson Date: Sat, 26 Jul 1997 12:12:30 +0000 Subject: The second of three steps to support main.aliases and mail.byaddr in ypserv. This time it's time for a new utility program mkalias.

Only useful together with +.Fl e +or +.Fl E . +.It Fl u +Assume UUCP names are OK. Only useful together with +.Fl e +or +.Fl E . +.It Fl n +Capitalize name. eg mats.o.jansson becomes Mats.O.Jansson. +.It Ar input +Use this map as input +.It Ar output +Use this map as output. If the output map isn't given don't create database. +Can be useful together with +.Fl e +or +.Fl E . +.El +.Sh BUGS +.Nm mkalias +on SunOS 4.1.x seems to have a +.Fl s . +Since I don't know what it is supposed to do I havn't implemented it.
