I'm trying to get a list of uniq IP addresses from a log file. I have a
list of ALL IP addresses. Using sort -nu and sort -n | uniq give me 2
A stare and compare make me think that sort -nu only considers the
first 2 octets as significant. RTFM of the sort man page indicates sort
LC_COLLATE isn't in env, so I'm assuming it's set at build/compile time
when building sort or in the c libraries someplace?
</appear uninformed -- hardly, stupid probably better tag... and not
Could this be why the sort -u and uniq return differing output? I don't
see anyplace to specify "how much" to consider significant when running
sort. Anyone care to offer thoughts?
