Hello Hagama,

Thanks a lot for the code...it works but I get duplicate names from all three columns from text files. I would prefer to have duplicate names only from the first columns of of text files. Could you please suggest a way to get that?

Thanks indeed!

If your files are large, such that keeping the entire list in memory might not be possible/practical, this should work:

Code:
awk '{ print FILENAME, $0 }'  file1 file2 file3  | sort -k 2,2 | awk '
    p != $2 {
        if( n > 1 )
            printf( "%s %s\n", p, f );
        n = 1;
        f = $1 " ";
        p = $2
        next;
    }
    {
        n++;
        f = f $1 " ";
    }'

More effort, but doesn't require everything to be kept in memory by awk.
