print the name of each package APT knows [matching a prefix]
In this case, linux- is the prefix; simply running $apt-cache pkgnames would list every package APT knows about. The default APT config assumes -g, --generate; to use the cache as/is, you could similarly run: $apt-cache --no-generate pkgnames [prefix] Adding --all-names, like so: $apt-cache --no-generate --all-names pkgnames [prefix] would print all the packages APT knows about, using the cache as/is, including virtual packages and missing dependencies. This command was shamelessly stolen from the apt-cache(8) man-page.
