Zitat

-b : Batch mode operation
Starts top in 'Batch mode', which could be useful for sending out-
put 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.

-d : Delay time interval as: -d ss.tt (seconds.tenths)
Specifies the delay between screen updates, and overrides the cor-
responding 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.
