While I believe the answer has already been found, would the 'uniq'

david,
Good question. Can it find a difference in a specific field and change
only one of them? Perhaps, but I've no idea.
Without a bigger sample size of data from you, I'm not sure.
I use the uniq command a lot when I pull a list of stuff (usually IPs
and more) with grep or other utilities from log files and then pipe
things through uniq to get a count of times an entry is found (-c flag).
Provided all data lines are unique, except for your one duplicate line,
then yes, you could use this. A crude, but effective approach to test
would be:
cat $file | uniq -u > $outfile
There are a lot of approaches, and I like the awk approach. This might
just be another tool for you to use in the future to satisfy other needs.
