CPU：
cat /var/run/dmesg.boot |grep CPU
sysctl hw.model hw.ncpu
dmesg | grep "CPU:"
查詢CPU核心數：
sysctl -a |grep ncpu
或者：
cat /var/run/dmesg.boot |grep Dete
再或者
sysctl hw.ncpu
Harddisk：
df -h
cat /var/run/dmesg.boot | grep da0
fdisk /dev/da0 |grep size
Menory info：
查詢方法一：
cat /var/run/dmesg.boot | grep memory
usable memory = 25755664384 (24562 MB)
avail memory = 24964411392 (23807 MB)
dmesg | grep "real memory" | awk -F '[( )]' '{print $2,$4,$7,$8}'
dmidecode -t memory|grep Size
查詢方法二：
sysctl -a | grep hw.physmem
hw.physmem: 25755664384
cat /var/run/dmesg.boot |grep Dete
cat /var/run/dmesg.boot | grep da0
cat /var/run/dmesg.boot | grep memory
SWAP
top | grep "Swap:" | awk '{print $1,$2}'
