Once again, I'm late to the party, wondering how in the world I never heard of ranger before yesterday. For me, it's an absolute game changer. It beats mc, the previous only console-based file manager I've seen, handily in terms of features, flexibility, aesthetics, and ease of use.

This will easily replace finder at work, and pcmanfm at home. It's in every major repo, including debian, redhat, arch, gentoo, and suse variants, and is available through homebrew too.
