Thanks both of you, that's my problem. I was thinking `-n -k 1,10' would sort on the first ten fields, numerically. Not take the first ten fields and sort them as if they were one number. I don't think sort(1) or the info doc. make this very clear, perhaps it could be improved? Thanks again, Ralph. _______________________________________________ Bug-coreutils mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-coreutils
