Linux command: top


NAME
       top - display Linux processes

SYNOPSIS
       top -hv|-bcHiOSs -d secs -n max -u|U user -p pid -o fld -w [cols]

       The traditional switches `-' and whitespace are optional.

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 processes or  threads  currently  being
       managed  by  the  Linux  kernel.  The types of system summary information shown and the
       types, order and size of information displayed for processes are all user  configurable
       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  --   encompassing  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 top's display and used when reading and writing a configuration
       file.
