NAME
dpkg-ruby - Utility to read a dpkg style db file, dpkg-awk clone
SYNOPSIS
dpkg-ruby [(-f|--file) filename] [(-d|--debug) ##] [(-s|--sort) list] [(-n|--numeric) list]
[(-rs|--rec_sep) ??] '<fieldname>:<regex>' ... -- <out_fieldname> ..
DESCRIPTION
dpkg-ruby Parses a dpkg status file(or other similarly formated file) and outputs the resulting records.
It can use regex on the field values to limit the returned records, and it can also be told which fields
to output. As another option, 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 outputted for each record. If the first field listed is begins
with ^, then the list that follows are fields NOT to be outputted.
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 program.
This program comes with no warranties. If running this program causes fire and brimstone to rain down
upon the earth, you will be on our own.
This program accesses the dpkg database directly in places, querying for data that cannot be gotten via
dpkg.
