   -c, --cpu-util=PCT,  Desired utilization of each CPU, in percent (default --cpu-util=RANGE   50%).  If 'curve' CPU usage mode is chosen, a range of the form MIN-MAX should be given.
+
   -n, --ncpus=NUM      Number of CPUs to keep busy (default: autodetected)
+
   -r, --cpu-mode=MODE  Utilization mode ('fixed' or 'curve', see lookbusy(1))

   -p, --cpu-curve-peak=TIME Offset of peak utilization within curve period, in seconds (append 'm', 'h', 'd' for other units)
+
   -P, --cpu-curve-period=TIME Duration of utilization curve period, in seconds (append 'm', 'h', 'd' for other units)
+
 Memory usage options:
+
   -m, --mem-util=SIZE   Amount of memory to use (in bytes, followed by KB, MB, or GB for other units; see lookbusy(1))

+
 Disk usage options:
+
   -d, --disk-util=SIZE Size of files to use for disk churn (in bytes,  followed by KB, MB, GB or TB for other units)
+
   -b, --disk-block-size=SIZE Size of blocks to use for I/O (in bytes, followed by KB, MB or GB)
+
   -D, --disk-sleep=TIME  Time to sleep between iterations, in msec (default 100)
-  -f, --disk-path=PATH Path to a file/directory to use as a buffer (default /tmp); specify multiple times for additional paths
