Compare Tab Separated Field with AWK to all and print lines of unique fields.

Hi.

I have a tab separated file that has a couple nearly identical lines. When doing:
Code:
sort file | uniq > file.new

It passes through the nearly identical lines because, well, they still are unique.

a)
I want to look only at field x for uniqueness and if the content in field x is the same as field x in any other line, move all the duplicate lines to a new file called file.duplicates.

b)
I also want to be able to look only at field x for uniqueness and if the content in field x is the same as field x in any other line, remove the following lines with the duplicate field x.

Thanks in advance!

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
