        Ya it's nice, ctrl+a, ctrl+e, and ctrl+d are nice too so you can stay at "home" on the keyboard.

          "sudo !!", "tail -f", the unholy trinity that is "grep/awk/sed", and vim (all from within tmux).

          I don't use awk as much as I should, I essentially use it for a glorified csv reader haha

                Hardware commands are always great:

                lspci

                Anything in /proc

                I LOVE LOVE LOVE htop

                  I honestly don't like htop very much. I prefer regular top. I find the output more useful.

                    htop works much better to see multi-CPU utilization though. Filtering is really nice too.

                      Ah, I never find CPU utilization to be something that I need to watch. Looks neat and impressive on the screen, but once I know the percentage of CPU, I don't care about seeing a chart, but I need to see load numbers, processes and memory stats.

                                        That's about all I got right now.
