mkisofs -o test.iso /mnt
mount -t iso9660 -o loop test.iso /mnt => iso를 마운트 할때
mkdir /iso
mount /dev/cdrom /iso => 연결된 iso 이미지는 가상머신의 /dev/cdrom 으로 연결됨
fdisk -l | grep 'Disk /dev/sd[b-z]' | awk '{ sub(/,/,""); sum +=$5;} END { print sum/1024/1024/1024 }'
또는
lsblk -o NAME,SIZE | egrep sd[b-z] |
nic - 고정 ip setting#!/bin/bash NIC 이름 NIC_NAME="ens3" 파일 수정 NetworkManager 재시작 |
