Centos 7 minimal, installing tmux app manager and fluxbox styles

I'm having difficulty installing things like tmux app manager and fluxbox styles. In both cases i attempt to tar into their directories ~/.tmux/plugins/tpm & ~/.fluxbox/styles like this sudo tar -xjf trinity.tar.bz2 ~/.fluxbox/styles however I get an error stating that /styles is not a directory. Same with /tpm. They are indeed there, but they are not directories. I'm very confused. Where do I unpack my tar files?
