You should probably elaborate on your question. atleast write your question in the post!

you REALLY aren't making any friends with your multiple accounts and hopelessly vague threads. If you wish to remain a valued member of this site, please use it better.

Can you elaborate a bit more on your requirements!!!

sort file_to_find_dupes | uniq -d

well no need to use uniq at all, sort has a unique option too, -u i *think*.

and bgeddy, please sort out your signature, it's horrible and is distorting the page layouts from all the -'s

Well I took it the OP wanted to output duplicates only so first sort the file then pass it to uniq -d to output duplicates only. Sorting unique just fives a unique list of values.

Sorry about that - ( it's never been mentioned before). Hopefully it's now OK ? :o
