Try this on for size:
Command line args to the script are the column number (1 based) and the input file name. If your field is numeric, you should use -k ${1}n,$1 instead.
Also, if you use sort -u sort will do the uniq for you without invoking a second process.

I am trying to re-format a .csv file using awk. I have 6 fields in the .csv file. Some of the fields are enclosed in double quotes and contain comma's inside the quotes. awk is breaking this into multiple fields.
Sample lines from the .csv file:

I am trying to use awk to print the unique entries in $2
So in the example below there are 3 lines but 2 of the lines match in $2 so only one is used in the output.

In the awk below I am trying to print the entire line, along with the header row, if $2 is SNV or MNV or INDEL. If that condition is met or is true, and $3 is less than or equal to 0.05, then in $7 the sub pattern :GMAF= is found and the value after the = sign is checked. If that value is less than...

For some reason I am having difficulty performing what should be a fairly easy task. I would like to print lines of a file that have a unique value in the first field. For example, I have a large data-set with the following excerpt:

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-jn m Join on the mth field of file n. If n is missing, use the mth field in each file.
-o list
Each output line comprises the fields specifed in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1)BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
