I wonder if you can do this in two steps:
1. Parse out the unique values from the thrid column into
    a file.
2. Run the processor on the script to print where the
    third column matches one of the values identified.
I dont know how to do this in a script.
I would write a simple Java program to do it.

Subject: [CentOS] Scripting help please....

Need a scripting help to sort out a list and list all the duplicate lines.

My data looks somethings like this


I need to sort this list and print all the lines where column 3 has a
duplicate entry.

I need to print the whole line, if a duplicate entry exists in column 3.

I tried using a combination of "sort" and "uniq" but was not successful.
