639 $ echo " 1 -1 2 -2 3 -3 " | sort -1 -2 -3 1 2 3 640 $ ... not a very good numeric sort. But: 640 $ echo " 1 -1 2 -2 3 -3 " | sort -nk1,1 -3 -2 -1 1 2 3 641 $ So, "to be sure and accurate", or perhaps just by habit, I use "-nk" for numeric sorting. Don't know about floating point or scientific or engineering notation. Or about DFSORT. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
