[TriLUG] sort(1) and IPAs

[Mike]

Try ipsort.sh [Not mine, unsure where I picked it up].  The sed line is
long, it will probable wrap in e-mail, be sure to unwrap it.

#!/bin/sh
## ipsort
## A filter to sort a file like /etc/hosts by IP address.

sed "s/^\($ip\)/\1./" | sort -n -t. +0 -1 +1 -2 +2 -3 +3 -4 | sed
"s/^\($ip\)./\1/"

Subject: [TriLUG] sort(1) and IPAs

Is there some magic set of options to sort(1) that will cause
it to correctly sort IP addresses correctly?  Particularly when
the data set will contain 2-, 3-, and 4-octet numbers?  (E.g.,
57.3, 57.3.4, and 57.3.4.211)
