top(1) - display Linux tasks
-b : Batch mode operation
     Starts  top  in 'Batch mode', which could be useful for sending output from top to other programs or
     to a file.  In this mode, top will not accept input and runs until the iterations limit  you've  set
     with the '-n' command-line option or until killed.

-c : Command line/Program name toggle
     Starts  top with the last remembered 'c' state reversed.  Thus, if top was displaying command lines,
     now that field will show program names, and  visa  versa.   See  the  'c'  interactive  command  for
     additional information.
-d : Delay time interval as:  -d ss.tt (seconds.tenths)
     Specifies  the delay between screen updates, and overrides the corresponding value in one's personal
     configuration file or the startup  default.   Later  this  can  be  changed  with  the  'd'  or  's'
     interactive commands.

     Fractional  seconds  are honored, but a negative number is not allowed.  In all cases, however, such
     changes are prohibited if top is  running  in  'Secure  mode',  except  for  root  (unless  the  's'
     command-line  option  was  used).   For additional information on 'Secure mode' see topic 5a. SYSTEM
     Configuration File.
-h : Help
     Show library version and the usage prompt, then quit.
-H : Threads toggle
     Starts top with the last remembered 'H' state reversed.  When this  toggle  is  On,  all  individual
     threads will be displayed.  Otherwise, top displays a summation of all threads in a process.
-i : Idle Processes toggle
     Starts  top  with  the  last remembered 'i' state reversed.  When this toggle is Off, tasks that are
     idled or zombied will not be displayed.

-n : Number of iterations limit as:  -n number
     Specifies the maximum number of iterations, or frames, top should produce before ending.
-u : Monitor by user as:  -u somebody
     Monitor only processes with an effective UID or user name matching that given.
-U : Monitor by user as:  -U somebody
     Monitor only processes with a UID or user name matching that given.  This matches  real,  effective,
     saved, and filesystem UIDs.
-p : Monitor PIDs as:  -pN1 -pN2 ...  or  -pN1, N2 [,...]
     Monitor  only processes with specified process IDs.  This option can be given up to 20 times, or you
     can provide a comma delimited list with up to 20 pids.  Co-mingling both approaches is permitted.

     This is a command-line option only.  And should you wish to return to normal operation,  it  is  not
     necessary to quit and and restart top  --  just issue the '=' interactive command.
-s : Secure mode operation
     Starts  top  with secure mode forced, even for root.  This mode is far better controlled through the
     system configuration file (see topic 5. FILES).

-S : Cumulative time mode toggle
     Starts top with the last remembered 'S' state reversed.  When 'Cumulative mode' is On, each  process
     is  listed  with  the  cpu  time  that  it and its dead children have used.  See the 'S' interactive
     command for additional information regarding this mode.
-v : Version
     Show library version and the usage prompt, then quit.
