I don't quite follow. The last six lines seem to claim that the following pairs of options are invalid: -D -c -G -c -D -G -D -u -u -d -D -d But -u -d is clearly valid, since POSIX says it's valid. In the documentation part of the patch that I sent, we have: (default) Discard the second and subsequent repeated lines. -d Discard lines that are not repeated. -u Discard the first repeated line. -D Do not discard the second and subsequent repeated lines, but discard lines that are not repeated. Under this convention, -D is not incompatible with -d or with -u. It is incompatible with -c, and the patched uniq.c checks for that. coreutils uniq does not have the -G option, but if it did it would behave like this: -G Do not discard the second and subsequent repeated line. That is, -D is equivalent to -d -G. Under this interpretation, -G is also incompatible with -c, but it's not incompatible with any other option. Perhaps it would be better for coreutils uniq to drop the -D option, and to have -G instead. With -G, one can easily simulate -D (since -D == -d -G), but the converse is not true. Or if backward compatibility is a concern, perhaps -G should be added. _______________________________________________ Bug-coreutils mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-coreutils
