Full screen, dynamic display of global and per-process resource usage by descending PID order.
top limits the total processes displayed to
Display counts in the specified
mode, which is one of the following:
Cumulative event counting mode. Counts are cumulative from top start time. -w and -k are superseded and ignored while -ca is in effect.
Delta event counting mode. Counts are deltas relative to a previous sample. -w and -k are superseded and ignored while -cd is in effect.
Absolute event counting mode. Counts are absolute values from process start times. -w and -k are superseded and ignored while -ce is in effect.
Non-event mode. CPU usage is calculated from previous sample.
Don't calculate on shared libraries. This greatly decreases top's system load.
Logging mode. Change display mode from periodic full screen updating to a sequential line mode output suitable for output redirection. The number of sequential snapshots is specified as
Limit to showing top
Display processes sorted by order. If preceded by a plus or minus sign, sort in ascending or descending order, respectively.
Number of Mach ports.
Number of memory regions.
Resident private address space size.
Resident shared address space size.
Resident memory size.
Number of threads.
