Linux: Show files from an apt package

As I search for these commands time and time again, I’ll just copy the Post which lists them all:

https://serverfault.com/questions/96964/list-of-files-installed-from-apt-package

To find which files were installed by a package, use dpkg -L:

$ dpkg -L $package

apt-file can tell you which files will be installed by a package before installing it:

root# apt-get install apt-file
root# apt-file update
$ apt-file list $package

NOTE: apt-file needs to be installed first (sudo apt-get install apt-file).

Or if you have the package as a .deb file locally already, you can run dpkg on it:

$ dpkg --contents $package.deb

To find which package provides a file that is already on your system, use:

$ dpkg -S /path/to/file

To find which package provides a file that is not currently on your system, use apt-file again:

$ apt-file search /path/to/file
