Used to be able to view the UNIX nice value of a process in the top CLI utility. I think it's gone from the top utility on Mavericks? Any other ways to view it?

Use ps with a lower case L to directly view current nice values:

ps -l

or for specific process id (PID)

ps -l -p __PID___

    Unfortunately, the display is bungled so you can't (mostly) grep for the command name. If you first do ps aux | grep -i theCommandName and then use the pid (first number after user name) in ps -l -p pid you won't have to do some fancy pid-filtering.

  • Emacs' built-in M-x proced is quite good as well.

Install GNU Coreutils via Homebrew, then use gnice. It only works for getting the current process' nice level though, AFAIk.
