will return a list of all dependencies, recommends and suggests of the
selected package (recursive: with all their respective dependencies,
recommends and suggests as well). Of course you can use the command
with only one "-s" to show only the recommended resp. suggested
packages (or without to get only the recursive dependency list).
As I have recommends and suggests disabled in my apt preferences, for
packages I am going to install I just run
# apt-get install <package>
and cancel the operation to append any useful recommended or suggested
packages I find listed in the output. Alternatively you can use the
"-s" or "--simulate" option to do an apt-get "dry-run". I believe
apt-get won't list already installed recommends / suggests.
