CPU 개수 확인 (물리 소켓 수)
[haedong@localhost:~]$ sudo grep "physical id" /proc/cpuinfo | sort -u | wc -l
1
CPU 코어 개수 확인 (물리)
[haedong@localhost:~]$ sudo grep "cpu cores" /proc/cpuinfo | tail -1
cpu cores : 4
CPU core 개수 확인 (논리)
[haedong@localhost:~]$ sudo grep -c processor /proc/cpuinfo
8
총 core 수 = 소켓수 * 논리 코어개수 * 하이퍼스레드

free -h
lsmem
sudo dmidecode -t memory
dmidecode -t memory 는 슬롯별 용량 · 속도 · 제조사까지 보여준다. root 권한이 필요하다.
lsblk -o NAME,SIZE,TYPE,MOUNTPOINT,FSTYPE,MODEL
df -hT
sudo nvme list
RAID 컨트롤러 뒤의 물리 디스크는 lsblk 에 보이지 않는다. 컨트롤러 전용 도구(storcli, perccli 등)를 써야 한다.
ip -br link
lspci | grep -i ethernet
sudo ethtool <인터페이스>
sudo ethtool -i <인터페이스>
ethtool 은 링크 속도와 듀플렉스를, ethtool -i 는 드라이버와 펌웨어 버전을 보여준다.
sudo dmidecode -t system -t baseboard -t bios
lspci
lsusb
sudo lshw -short
lshw 는 배포판에 따라 기본 설치가 아니다. dnf install -y lshw 로 넣는다.
