I just sent out the rmgroups for the rest of the old net. groups (except net.sources). The only valid net group is net.sources and its children. Since most of you have MANUALLY defined, the following shell script should be of use. If you aren't using ORGDISTRIB, comment out the marked part and uncomment the doit=rmgroup. Else, set $ORG = the appropriate distribution and turn it loose. ---rick # doit=/usr/lib/news/rmgroup # # or this part if you use ORGDISTRIB doit=/tmp/doit$$ cat >/tmp/doit$$ <<'EOF' #!/bin/sh # define your local distribution as "-d ORG" ORG="-d css" for i do /usr/lib/news/inews -n $i.ctl -c rmgroup $i $ORG -a $USER</dev/null done EOF chmod 755 /tmp/doit$$ #end of ORGDISTRIB section $doit net.wobegon net.wines net.video net.veg net.tv.soaps net.tv.drwho $doit net.tv net.trivia net.travel net.startrek net.sport.hoops $doit net.sport.hockey net.sport.football net.sport.baseball net.sport $doit net.sf-lovers net.rec.wood net.rec.skydive net.rec.ski net.rec.scuba $doit net.rec.photo net.rec.nude net.rec.bridge net.rec.boat net.rec.birds $doit net.rec net.railroad net.puzzles net.puzzle net.poems net.pets $doit net.music.synth net.music.makers net.music.gdead net.music.folk $doit net.music.classical net.music net.movies net.mag net.jokes.d $doit net.jokes net.ham-radio.packet net.ham-radio net.garden net.games.video $doit net.games.trivia net.games.rogue net.games.pbm net.games.hack $doit net.games.go net.games.frp net.games.emp net.games.chess net.games.board $doit net.games net.cycle net.cooks net.comics net.chess net.books $doit net.bicycle net.aviation net.auto.tech net.auto net.audio $doit mod.movies mod.mag net.announce.arpa-internet rm -f /tmp/doit$$

I got all the rmgroups. Unfortunately, I found out the hard way that rmgroup still doesn't lock the active file while doing its work, so if news is coming in while you're rmgroup'ing, you'll corrupt your active file.

The article I'm following up was originally posted to ca.news, but this may be a wider problem so I'm crossposting to news.admin and removing the distribution restriction. In article <1372@cit-vax.Caltech.Edu> mangler@cit-vax.Caltech.Edu (System Mangler) writes: >We got the rmgroups (twice!) but looking in the log file, I notice >that they didn't get sent to elroy. I think this is because the >distribution is "na", and in the sys file line that sends net.* >to elroy, I neglected to list any distributions. Oops. AHA! I'll bet that's the reason so many people didn't get the rmgroups! OK you news admins, check your sys files! Make sure everyone in North America gets "na", everyone in the USA gets "usa", and any local distributions (or distributions for your country and continent, for that matter) are right. -- - Joe Buck {hplabs,ihnp4,sun}!oliveb!epimass!jbuck HASA (A,S) Entropic Processing, Inc., Cupertino, California

Here is a locknews (and unlocknews) program which uses the same locking
scheme as the rest of 2.11 news. I've only tested it on System V machines,
but the code is there for other systems and it should work unless I've made
some silly mistake in the coding. Feel free to post fixes as they are found.
The following shar contains the code for locknews/unlocknews, plus patches
for Makefile.dst and rmgroup.sh to build and use the new process. I put the
same copyright comment at the top of the code which is found on top of all
of the rest of the 2.11 code. On System V machines, only epathinit.o needs
to be linked in, but this may not be true for other systems.
This pair of processes can also be used whenever you're doing some work on
the news system. Simply run locknews, do your work, and then run unlocknews.
The code is being mailed to Rick as well as being posted.
