Re: "sort" problem

You could use this which specifies the field to sort on:

sort -t. -k 2n,2 XX

This defines a period as the field separator and tells it to sort on the
second field

Subject: "sort" problem

AIXers,

Given a file "XX" whose contents are the following:
219.144.82.44
219.133.253.24
219.133.146.220
219.133.136.94
219.133.65.24
219.133.11.177

I'm trying to sort "XX" so the results are as follows:
219.133.11.177
219.133.65.24
219.133.136.94
219.133.146.220
219.133.253.24
219.144.82.44

I've tried the following sort :
sort -u -d -t. +0 -n +1 -n +2 -n +3 -n XX

But the results are as follows: (The 3rd column is out of order)
219.133.11.177
219.133.136.94
219.133.146.220
219.133.253.24
219.133.65.24
219.144.82.44

When I do sort -u -d -t. +2 -n +3 -n XX (The 3rd & 4th columns are in
order)
I get the following:
219.133.11.177
219.133.65.24
219.144.82.44
219.133.136.94
219.133.146.220
219.133.253.24

I've also tried the following which work OK on the column specified:
 sort -u -d -t. +3 -n XX
 sort -u -d -t. +2 -n XX
 sort -u -d -t. +1 -n XX

What am I missing in the sort:
sort -u -d -t. +0 -n +1 -n +2 -n +3 -n XX

?
