`stress' imposes certain types of compute stress on your system\n\nUsage: stress [OPTION [ARG]] ...\n -?, --help         show this help statement\n     --version      show version statement\n -v, --verbose      be verbose\n -q, --quiet        be quiet\n -n, --dry-run      show what would have been done\n -t, --timeout N    timeout after N seconds\n     --backoff N    wait factor of N microseconds before work starts\n -c, --cpu N        spawn N workers spinning on sqrt()\n -i, --io N         spawn N workers spinning on sync()\n -m, --vm N         spawn N workers spinning on malloc()\/free()\n     --vm-bytes B   malloc B bytes per vm worker (default is 256MB)\n     --vm-stride B  touch a byte every B bytes (default is 4096)\n     --vm-hang N    sleep N secs before free (default none, 0 is inf)\n     --vm-keep      redirty memory instead of freeing and reallocating\n -d, --hdd N        spawn N workers spinning on write()\/unlink()\n     --hdd-bytes B  write B bytes per hdd worker (default is 1GB)\n\nExample: stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 10s\n\nNote: Numbers may be suffixed with s,m,h,d,y (time) or B,K,M,G (size).<\/code><\/pre>\n\n\n\n
