CPU資料
查CPU，查model name及cpu數(幾核)

cat /proc/cpuinfo |grep 'model name'|tail -n1
cat /proc/cpuinfo |grep 'model name'|wc -l

操作畫面

# cat /proc/cpuinfo |grep 'model name'|tail -n1
model name	: Intel(R) Xeon(R) Silver 4214 CPU @ 2.20GHz
# cat /proc/cpuinfo |grep 'model name'|wc -l
24

如果有lscpu指令，可取更新清楚的資訊

lscpu

底下....略.....

記憶體
查記憶體有多少

grep MemTotal /proc/meminfo
egrep 'MemTotal|MemFree|MemAvailable' /proc/meminfo

實際操作畫面

$ egrep 'MemTotal|MemFree|MemAvailable' /proc/meminfo
MemTotal:       82024272 kB
MemFree:        51008940 kB
MemAvailable:   74909208 kB

如果有free指令可用如下指令，更清楚

$free -h
               total        used        free      shared  buff/cache   available
Mem:            78Gi       4.1Gi        48Gi       1.8Gi        25Gi        71Gi
Swap:          8.0Gi          0B       8.0Gi

硬碟空間
磁碟可用df指令檢測

df -h
Filesystem                         Size  Used Avail Use% Mounted on
tmpfs                              7.9G  6.6M  7.9G   1% /run
/dev/mapper/ubuntu--vg-ubuntu--lv   98G   35G   58G  38% /
tmpfs                               40G     0   40G   0% /dev/shm
tmpfs                              5.0M     0  5.0M   0% /run/lock
/dev/sda2                          2.0G  248M  1.6G  14% /boot
/dev/sda1                          1.1G  5.3M  1.1G   1% /boot/efi
tmpfs                              7.9G  4.0K  7.9G   1% /run/user/0
tmpfs                              7.9G  4.0K  7.9G   1% /run/user/1000

如果要漂亮的畫面我們也可以用neofetch速查，通常需另行安裝。

例如:
Manjaro Linux會像這樣
