sort command
 

Hi,

I want to sort a file contains

9 1
9 2
10 1
10 2

to the order of

10 1
9 1
10 2
9 2

That is, the 2nd column is in incremental order, but for lines with the same 2nd column number, they are sorted in a reversed order.

I tried
Sort –k2 –k1 –n –r
But got everything in reversed order

10 2
9 2
10 1
9 1

Is there any simple way that works? Right now, I have to write a script to process this.

Thanks,

Sure is

sort -k2,2n -k1,1nr

Edit: ops... too late! ;)

Great, thanks for both of you!!!
