There is only one sort key, which spans the first two fields of each line, and -n tells sort to only consider the numeric prefix of each key. If you want to sort on multiple keys you need to specify each key separately. $ echo 1/3,1/2,1/1,2/1 | tr , \\012 | sort -nu -t / -k 1,1 -k2,2 1/1 1/2 1/3 2/1 Andreas. -- Andreas Schwab, SuSE Labs, [EMAIL PROTECTED] SuSE Linux Products GmbH, Maxfeldstraße 5, 90409 Nürnberg, Germany PGP key fingerprint = 58CA 54C7 6D53 942B 1756 01D3 44D5 214B 8276 4ED5 "And now for something completely different." _______________________________________________ Bug-coreutils mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-coreutils
