Hi,
This seems wrong.
$ echo 1/3,1/2,1/1,2/1 | tr , \\012 | sort -nu -t / -k 1,2
1/3
2/1
$
-u should only filter out lines that compare equal on *all* key fields.
I've opened an Ubuntu bug at
https://launchpad.net/distros/ubuntu/+source/coreutils/+bug/56891 which
has more detail and examples. I was hoping someone here could either
confirm it's a bug or point out my misunderstanding.
Cheers,
Ralph.
