There is no reason why awk can't be used interactively.
You are 100% right about that. So we have no argument. Smilie But I did want to clarify that I never said "awk can't be used interactively". I said it's not intended as an interactive environment. I stand by that, because awk is normally used in a batch mode.

You are a very advanced user. So you are comfortable using awk in an interactive mode. And, as you say, you are normally testing when you run awk interactively. If you read again the original post, I'm sure you will agree the poster obviously has a VERY confused understanding, is at a pretty beginner level, because the poster thinks read and break are related. We all started at a beginner level, at one time or another. When explaining something to a beginner user, I think it's best to stick with the basics. We have to walk before we can run.

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
