I left out some details but I basically have a bunch of *.csv's that I am trying to collect together into one file. The format of each *.csv matches what I posted earlier, where the filename is the first record and the second line is the data. Is there a good way to add a header row at the top of the output file? For some reason I don't believe my shell is working the way it is supposed to, so I am resorting to calling awk once to create the output file with the header row and then on the second call to populate it. Either way, thanks for your help!

My awk script looks like:
BEGIN{
RS="\n"
FS="*"
OFS=","
ST1="Channel Number"
ST2="Channel Label"
ST3="Time at Max"
ST4="Time History Max"
ST5="Time at Min"
ST6="Time History Min"
ST7="Frequency at Max Response"
ST8="Max Response"
}
{
if (FNR==1)
outputfile=$1
print ST1 ST2 ST3 ST4 ST5 ST6 ST7 ST8 >outputfile
if (FNR==2)
print $1 $2 $3 $4 $5 $6 $7 $8 >>outputfile
}
I thought this would work but it doesn't

DPKG-AWK(1) General Commands Manual DPKG-AWK(1)
NAME
dpkg-awk - Utility to read a dpkg style db file
SYNOPSIS
dpkg-awk [(-f|--file) filename] [(-d|--debug) ##] [(-s|--sort) list] [(-rs|--rec_sep) ??] '<fieldname>:<regex>' ... -- <out_fieldname> ..
DESCRIPTION
dpkg-awk Parses a dpkg status file (or other similarly formatted file) and outputs the resulting records. It can use regex on the field
values to limit the returned records, it can also be told which fields to output, and it can sort the matched fields.
OPTIONS
-f filename
--file filename
The file to parse. The default is /var/lib/dpkg/status.
-d [#]
--debug [#]
Each time this is specified, it increased the debug level.
-s field(s)
--sort field(s)
A space or comma separated list of fields to sort on.
-n field(s)
--numeric field(s)
A space or comma separated list of fields that should be interpreted as numeric in value.
-rs ??
--rec_sep ??
Output this string at the end of each output paragraph.
-h
--help Display some help.
fieldname
The fields from the file, that are matched with the regex given. The fieldnames are case insensitive.
out_fieldname
The fields from the file, that are output for each record. If the first field listed begins with ^, then the list of fields that
follows will NOT be output.
BUGS
Be warned that the author has only a shallow understanding of the dpkg packaging system, so there are probably tons of bugs in this pro-
gram.
This program comes with no warranties. If running this program causes fire and brimstone to rain down upon the earth, you will be on your
own.
This program accesses the dpkg database directly in places, querying for data that cannot be gotten via dpkg.
