grep-dctrl

Posted by semifor at November 30. 2005
The other day, I stumbled upon this entry about the vrms package:
http://www.debian-administration.org/users/orchid/weblog/5

vrms (Virtual Richard M. Stallman) displays a list of installed, non-free packages.

Having just recently read the The Debian System section 5.11.9, page 254, which discusses grep-dctrl and its variants, I thought that perhaps the same result could be obtained with tools already installed.

The following command gives me the list of installed non-free packages on my system.

grep-status --show Package --field=Section non-free \
--and --field=Status 'ok installed'

It's nice to know how to use the tools you have.

I bet vrms exists mostly for the name. Thanks for taking the time to figure out how to use grep-dctrl to achieve the same. It is truly a very useful tool, and getting better every day -- the developer is actively working on it.

Richard Bejtlich, Tao Security: Prospective TDS readers should understand that this book is unlike any I have read on operating systems. Readers will not have to skip pages on setting up Apache or configuring BIND, thankfully! Instead, TDS covers core system administration subjects to a degree I have not seen elsewhere. [...] Krafft takes readers on an inside tour of the how and why of Debian. Rather than just explaining a technique or tool, the author discusses the overall problem, possible ways to approach it, and Debian's solutions. He presents pros and cons for each, and then demonstrates usage with command line syntax and sample output.
