Locating Dependencies for a Package via Apt

carlosinfl · 05-13-2009, 07:21 PM

I have read the apt-get man page fairly well now and can't be sure how to list the dependencies of a specific package. It's nice to know if a package is NOT installed, what packages are required. Or if a package IS installed, what packages depend on the installed package.

I tried the -V option but I keep getting an error

apt-cache -V <package>
apt-get -V <package>

Anyone know how I can find the desired output via CLI?

***Ahh, I think I was looking for <dpkg -p <package_name>>***

apt-cache show packagename will show package info , pretty much the same as dpkg -p
apt-cache policy packagename will show if it is installed and what version is available to be installed
apt-cache rdepends will show the reverse depends
