Manual page and help for the top linux command. The top program provides a dynamic, real-time view of the running system. Displays system summary information and a list of processes or threads currently managed by the Linux kernel. The types of system summary information displayed, as well as the type, order, and size information displayed for processes, are all configurable by the user and remain after the reboot. The program provides a limited interactive interface for managing processes, as well as a much more extensive interface for personal configuration - covering all aspects of how it works.
