Thanks for the reply.

The data file is a large data file from the Federal government.

I would like to read the data using stat software packages.

The lines end with \r\n .

Field 4 is a text field. It can have a \n character embedded in it. Stat software package tends to incorrectly split a record with a \n character into two records. Commas are a legitimate part of field 4 (so I should not have had it removed in the sample output). Field 4 is all caps.

I have tried things like

Code:
awk -F"|" '{ print $1f"|"$4F }' < patienttest2.txt | sed 's/,/comma/g' | sed 's/|/,/' | sed 's/;/,/g' | awk -F , '{for (i=2;i<=NF;i++) if ($i>=0) print $1 FS $i}' | sed 's/co
mma/,/g' |

extracting field 1 (the id variable) and field 4 (the value of intereset) from a file

changing "," to "comma" because lowercase letters are not in the datafile

change the pipe to a comma.

the 2nd awk statement was to reshape fields 1 and 4 so that there a line with the id variable for each field 4.

the last sed is to swap "comma" out for "," .

Thanks!

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. AUTHOR
