CentOS lsblk命令详解

"lsblk"就是列出块设备。除了RAM外，以标准的树状输出格式，整齐地显示块设备。

01root@tecmint:~# lsblk02
03NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT04sda 8:0 0 232.9G 0 disk05├─sda1 8:1 0 46.6G 0 part /06├─sda2 8:2 0 1K 0 part07├─sda5 8:5 0 190M 0 part /boot08├─sda6 8:6 0 3.7G 0 part [SWAP]09├─sda7 8:7 0 93.1G 0 part /data10└─sda8 8:8 0 89.2G 0 part /personal11sr0 11:0 1 1024M 0 rom
“lsblk -l”命令以列表格式显示块设备(而不是树状格式)。
01root@tecmint:~# lsblk -l02

注意：lsblk是最有用和最简单的方式来了解新插入的USB设备的名字，特别是当你在终端上处理磁盘/块设备时。
