On ubuntu I would like to know which files that will be installed when running sudo aptitude install ruby-rvm.
So first I do sudo aptitude download ruby-rvm. Now I can do aptitude show ruby-rvm, but how can I get the list of files that will be installed during a sudo aptitude install ruby-rvm? something like dpkg -L ruby-rvm if I had installed it, I just want to know it before I install it.
I am not sure if aptitude can do such a thing. But you can use:
apt-file show package_name
It will show all files which this package will install. If you would like to list all files which package contains, you can do it like this:
apt-file list package_name
It will list all the files located inside a package.
If you do not have installed apt-file then use:
apt-get install apt-file
and update the cache (it will take some time) by:
apt-file update
You can also to which package specific file belongs:
apt-file search file_name
You can also list files in a package on this website List files in package
Or you can use dpkg -L package_name (but as you mentioned, it is working on already installed packages) as mentioned by @topdog.
aptitude does not have the ability to show the files installed per package, use dpkg -L for that
