You can have a look at the LSB headers in the ccpd package and add CUPS to the list of requirements. If you have done that already, I am out of luck :) – Nevertheless, posting your LSB headers here might not hurt.

Anyway, it is nice way to show how these --disable-columns -F '%p' are used for scripting. I tend to use interactive mode with "l". It was refereshing to find these tricks for command line scripting in current manpages. Thanks. Osamu PS: I got lost since it should be something like $ aptitude --disable-columns -F '%p' search '~c' | sudo xargs dpkg --purge to get dpkg to work as root while running aptitude in user mode. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

True, but aptitude isn't actually doing any package management there (it could be run as a non-root user). If you have something against it, I figured maybe just using it to generate a list of packages, to be processed later with an acceptable tool, might be more palatable.

But is it really necessary if output is not a terminal? ;)

Well, use aptitude then! :-)
I think "aptitude purge ~c" is much simpler than a command like:
COLUMN=200 dpkg --list | awk '/^rc/ {print $2}' | xargs -r dpkg -P --

I hacked up this little script, which i often use:
apt-get autoclean;
apt-get autoremove;
orphaner;
rm -f /var/cache/apt/archives/*.deb
dpkg --purge $(dpkg --list |grep ^rc |awk '{print $2;}');
The line you want is the last one, that i got off the net somewhere.

Re: dependency based boot sequencing
> # aptitude purge ~c Thanks for that suggestion but I don't use aptitude..I use apt, dpkg, and smartpm. dpkg -P works but it would seem each package must be listed seperately. Is there a command that gets all the unpurged stuff in one go, like your suggestion above with apititude? Apropos to my subject thread, I had to rebuild my system from a recent image after sysv-rc was installed on a dist-upgrade. Sid was completely inaccessable via grub2. It was as if there was no hard drive on the computer. Grub has a lot of commands and options, busybox too but if there's no hard drive all the commands in the world can't help you.

Sure, but it is easier to use aptitude: # aptitude purge ~c Regards, Andrei -- If you can't explain it simply, you don't understand it well enough.
