Ubuntu / Linux 掛載已格式化磁碟 (重啟系統後自動掛載)
1. 已掛載磁碟資訊，顯示 Linux 系統上的檔案系統的磁碟使用情況統計
[email protected]:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 63G 0 63G 0% /dev tmpfs 13G 11M 13G 1% /run /dev/sda6 211G 7.5G 193G 4% / tmpfs 63G 968K 63G 1% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 63G 0 63G 0% /sys/fs/cgroup /dev/sda1 922M 121M 738M 15% /boot /dev/sdb1 1.8T 2.5G 1.7T 1% /home tmpfs 13G 12K 13G 1% /run/user/108 tmpfs 13G 56K 13G 1% /run/user/1000 tmpfs 13G 60K 13G 1% /run/user/1002 tmpfs 13G 48K 13G 1% /run/user/1003 tmpfs 13G 52K 13G 1% /run/user/1004
2. 列出所有分割槽，檢視磁碟資訊
