Hm, no "lsb_release -a" under system? Also, I've come to rely more on ls -l /proc/${some_pid}/fd than lsof -- but if you only have to choose one, I suppose lsof is better.


lsof is much more useful when you want to see which process has a file open rather than the inverse.


I suppose I've just gotten a better intuition from ps/top than I used to have. I agree lsof is useful!


lsof also has some brilliant selection and filtering options. Really useful for checking for rogue high port sockets and other obscure things.
