Hi Guys,
I am trying to reading in comma seperated values in awk. I can set the delimiter to be a comma, but the tricky part is that commas that appear within quotes are not to be considered as delimiters. Could someone please help.

PVS(8) System Manager's Manual PVS(8)
NAME
pvs - report information about physical volumes
SYNOPSIS
pvs [-a|--all] [--aligned] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--nameprefixes] [--noheadings] [--nosuffix] [-o|--options
[+]Field[,Field]] [-O|--sort [+|-]Key1[,[+|-]Key2[,...]]] [-P|--partial] [--rows] [--segments] [--separator Separator] [--unbuffered]
[--units hHbBsSkKmMgGtTpPeE] [--unquoted] [-v|--verbose] [--version] [PhysicalVolume [PhysicalVolume...]]
DESCRIPTION
pvs produces formatted output about physical volumes.
OPTIONS
See lvm for common options. --columns.
--all Include information in the output about devices that have not been initialized with pvcreate.
--aligned
Use with --separator to align the output columns.
--nameprefixes
Add an "LVM2_" prefix plus the field name to the output. Useful with --noheadings to produce a list of field=value pairs that can
be used to set environment variables (for example, in udev (7) rules).
--noheadings
Suppress the headings line that is normally the first line of output. Useful if grepping the output.
--nosuffix
Suppress the suffix on output sizes. Use with --units (except h and H) if processing the output.
-o, --options
Comma-separated ordered list of columns. Precede the list with '+' to append to the default selection of columns.
Use -o pv_all to select all physical volume columns, and -o pvseg_all to select all Physical Volume segment columns.
Use -o help to view the full list of columns available.
Column names include: pv_fmt, pv_uuid, dev_size, pv_name, pv_mda_free, pv_mda_size, pe_start, pv_size, pv_free, pv_used, pv_attr,
pv_pe_count, pv_pe_alloc_count, pv_tags, pv_mda_count, pv_mda_used_count, pvseg_start, and pvseg_size.
With --segments, any "pvseg_" prefixes are optional; otherwise any "pv_" prefixes are optional. Columns mentioned in vgs (8) can
also be chosen. The pv_attr bits are: (a)llocatable, e(x)ported and (m)issing.
--segments
Produces one line of output for each contiguous allocation of space on each Physical Volume, showing the start (pvseg_start) and
length (pvseg_size) in units of physical extents.
-O, --sort
Comma-separated ordered list of columns to sort by. Replaces the default selection. Precede any column with - for a reverse sort on
that column.
--rows Output columns as rows.
--separator Separator
String to use to separate each column. Useful if grepping the output.
--unbuffered
Produce output immediately without sorting or aligning the columns properly.
--units hHbBsSkKmMgGtTpPeE
All sizes are output in these units: (h)uman-readable, (b)ytes, (s)ectors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes,
(p)etabytes, (e)xabytes. Capitalise to use multiples of 1000 (S.I.) instead of 1024. Can also specify custom units e.g. --units 3M
--unquoted
When used with --nameprefixes, output values in the field=value pairs are not quoted.
