Re: 'rpm --freshen': dpkg Equivalent?
Hi. This isn't a silly question at all. For a long time I would use dselect to just update the list of available packages, then I have to view them just to get back out to the prompt to "update". However, this will do the same: apt-get update ; apt-get upgrade The first updates the list of available packages from the archives in your /etc/apt/sources.list, the second will upgrade the installed packages to their latest version. Using dselect did give me a couple of good things, though. Right at the top of the package list are the "New" ones, to browse through just in case I decide to try something new. But I also run "unstable", so there are often new things to try.

You may succeed with one of the following two suggestions (change syntax of
"if" according to shell)
if (dpkg -l package-name | grep -c ii ) apt-get install package-name;
if (dpkg -l package-name | grep -c ii ) dpkg -i ./package.deb;
But I still don't understand why you wish to do all this. In most cases it is
easier to upgrade all packages at once:
apt-get update && apt-get upgrade
Good luck
Niels

Why not just: # cp /cdrom/*deb /var/cache/apt/archives # apt-get update # apt-get upgrade Any debs that are already in H:/var/cache/apt/archives won't be re-downloaded. The caveat is that any relevant packages that have been moved into sarge in the interregnum will get downloaded.

jh> why would you just one specific package to be updated? Sorry I didn't explain more. Here's the situation ... I have an office machine, O, and a home machine, H both using sarge/testing. O has a high-speed connection to the Internet, but H doesn't. After "updating" O, I copy all the .deb files in O:/var/cache/apt/archives to removable media and bring them home. Once home, I basically do a "dpkg -i *.deb" of the files copied from O. (It's actually a bit more complicated due to dependencies ...) Herein lies the problem. There are packages I install/run on O (e.g., 'mailman') that I do not want to install/run on H. However, if I quickly do "dpkg -i *.deb" on H, it'll install *all* the .debs -- including 'mailman'. Though I *could* write a script to accomplish what I want (i.e., ensuring each package is present before upgrading), I thought there might be an easier approach via a 'dpkg' command-line option (similar to "rpm -F"). Hopefully what I'm trying to do is now clearer ... Thanks for the responses! -Kenneth PS I realize I could also use 'apt-zip'. But so far, the above approach has worked pretty well ... -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Sorry, missunderstood your question.
Forget that, and read Joris Mail instead.

The only way I know (got through the package localepurge) is the
following:
apt-get -u --reinstall --fix-missing install $(dpkg -S LC_MESSAGES | cut -d:
-f1 | tr ', ' '\n' | sor
t -u)
But there might be a simpler ways I'm not aware of.

In other words:
o If the package is already installed, then update it
o If the package is not installed, do nothing (do *not* install it)
Sorry if this is obvious, but I can't seem to find out how to do it!
Thanks,
apt-get upgrade/apt-get dist-upgrade (after apt-get update) will upgrade
all packages; why would you just one specific package to be updated?
HTH,
Joris
