apt-get question

pkoebbe · 06-25-2003, 06:45 AM

What is the apt-get equivalent of rpm -q? For example, if I want to see what version of squid is installed (if any), with rpm I'd do:

rpm -q squid

and it would return either the version installed or that it's not available. How would I accomplish the same thing with apt-get?

Peace,
Phillip

Hi,

apt-get is just a "frontend" to the package-manager DPKG. DPKG is the eq to RPM so you just have to do a:

dpkg -l | grep $package

and then you can see the version.

You can also use

apt-cache show $package

but this one shows the information and version of the latest package in /var/cache/apt/*Contents-$arch.gz which doesn't have to be installed

btw. if your looking for a file and want to know in which package it is use apt-file search $filename

stony, how did I know you'd provide the answer?

That was *exactly* what I was looking for, and it's even better than the rpm solution!

Peace,

Hi

How can I download the necesary packages into a CD-R or CD-RW or to a directory/folder in my HDD without installing?

I read that you can use apt-get -d packagename

How do I control where these get downloaded to? Supposing there is a diretory called mydebs, how do I use apt-get -d postgresql and see that all the postgrewsql related packages are downloaded into mydebs??

Thanks for any help with apt

oops! I read it. Maybe it is not good enough or I am not good enough to understand it

Just run

# apt-get -d install <package>

The downloaded .deb will be put in /var/cache/apt/archives, unless you change that in the apt.conf which I wouldn't recommend doing.

If you're looking to build a mini mirror check out apt-move. You can then make an iso image out of your mini mirror with debian-cd.

Hi,

use the mirror script if you want to download a mirror. And also if you want do have up to date cds, build 'em with jigdo, then copy 'em to the harddrive and then do a rsync with this "image" (don't make an image of the cd an then run rsync over the mounted image, won't work if the new packages are bigger then the old ones ...)
