Here's a brain teaser for you UNIX tool-and-shell gurus out there. My news-reader presents articles in the order they appear in my .newsrc file. How can I sort it by subject? (I don't want to do it by hand because it seems like there's two or three new newsgroups a day.) If I just sort (no options) my .newsrc I get something like comp.lang.c++: comp.zillions.of.other.things: comp.std.c++: sci.random.stuff: rec.c++: talk.bizarre: talk.politics.oop.c++: and so forth. The articles on (C++) are not clumped together the way I want them. But because the c++ appears at a different depth in the name of each newsgroup, sort -t. +5 -6 +4 -5 +3 -4 +2 -3 +1 -2 .newsrc > puke won't work either. What am I missing? Surely there's got to be an easy way to do this.

It only orders by the last member of the hierarchy, which is not very helpful (as you can see by running a large .newsrc through this process). For example, foo.c++.bugs would be collected with other *.bugs, not with other c++ groups.

While I see little value in the original poster's desires, Doug's comment on Skip's solution is easily taken care of with out AI type code. To wit: cut -d: -f1 .newsrc | awk -F. ' { for (i = NF; i >= 1; i--) printf("%s ", $i) print "" }' | paste -d: - .newsrc | sort | cut -d: -f2- > puke And should you not have cut (a Xenix related deficiency) let me know and I'll provide an awk/shell script to mimic it. Or perhaps there is a ???.sources version around. Jon -- Jon LaBadie {att, princeton, bcr}!jonlab!jon {att, attmail, bcr}!auxnj!jon

The following short shell script seems to do what Luke wanted [ sorts by last part of newsgroup name ] > foo.c++.bugs would be collected with other *.bugs, not with other c++ groups. Hmmm. Perhaps remove the tail from *.misc, then collect foo.bar.* under foo.bar whenever the latter exists. Does this do the trick? ---Dan

I have to files that are in no particular order, but common numbers in one.
Is there any way to sort the data in one file to be in the order of the other?
One of these files can't be sorted because it is a pointer file and needs
the record offsets to stay the same.
Ex:
File 1 File 2
------ ------
I need file 2 to be: 100
100 500 500
500 100 300
500 300
500
300
300
Anybody have any ideas? (awk,shell,perl (which i'll get if i have to), or
even a C algorythm)
Thanks,
