系统版本:
[root@node1 ~]# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
[root@node1 ~]# uname -r
3.10.0-229.el7.x86_64
~： 自动展开为用户的家目录，或指定的用户的家目录
示例：
[root@node1 network-scripts]# cd ~
[root@node1 ~]#
{}： 可承载一个以逗号分隔的路径列表，并能够将其展开为多个路径
示例： 在/tmp创建以下目录，a_c，a_d，b_c，b_d
[root@node1 ~]# mkdir -v {a,b}_{c,d}
mkdir: created directory ‘a_c’
mkdir: created directory ‘a_d’
mkdir: created directory ‘b_c’
mkdir: created directory ‘b_d’
示例： 在/tmp/mylinux下创建目录结构
先了解tree命令：
以树状结构列出目录内容。
语法： tree [options] [directory]
选项： -L level: 指定要显示的层级
安装： yum -y install tree
[root@node1 ~]# mkdir -pv /tmp/mylinux/{bin,etc/sysconfig/network-scripts,sbin,usr/\
{bin,lib,lib64,local/{bin,etc,lib,sbin},sbin},var/{cache,log,run}}
mkdir: created directory ‘/tmp/mylinux’
mkdir: created directory ‘/tmp/mylinux/bin’
mkdir: created directory ‘/tmp/mylinux/etc’
mkdir: created directory ‘/tmp/mylinux/etc/sysconfig’
