description
the top program provides a dynamic real-time view of a running system. it can
display system summary information as well as a list of tasks currently being
managed by the linux kernel. the types of system summary information shown and
the types, order and size of information displayed for tasks are all user config-
urable and that configuration can be made persistent across restarts.

the program provides a limited interactive interface for process manipulation as
well as a much more extensive interface for personal configuration -- encom-
passing every aspect of its operation. and while top is referred to throughout
this document, you are free to name the program anything you wish. that new
name, possibly an alias, will then be reflected on topâs display and used when
reading and writing a configuration file.
