mkdir命令用于创建目录,如同一路径下创建单个或多个目录、递归创建目录,但同路径下不能创建同名目录,且目录名区分大小写。
【命令】
mkdir
【用途】
创建目录(单个目录/多个目录)
【语法】
mkdir [选项]...目录名...
【示例】
切换到当前目录:/usr/local/linuxStudy,所有示例在此路径下操作。
[root@testserver linuxStudy]# pwd
/usr/local/linuxStudy
例1.创建单个目录dir1
[root@testserver linuxStudy]# mkdir dir1 [root@testserver linuxStudy]# ls dir1
例2.一次创建多个目录:dir2,dir3
[root@testserver linuxStudy]# mkdir dir2 dir3 [root@testserver linuxStudy]# ls dir1 dir2 dir3
例3.同路径下创建同名目录:dir1-->创建失败,同路径下不能创建同名目录
[root@testserver linuxStudy]# mkdir dir1 mkdir: cannot create directory `dir1‘: File exists
例4.-p参数,创建多层目录dir4/dir5(dir4目录不存在时,同时创建dir4、dir5目录;dir4目录存在时,则只创建dir5目录)
[root@testserver linuxStudy]# mkdir dir4/dir5 #未加-p参数,上层目录不存在时,创建目录失败 mkdir: cannot create directory `dir4/dir5‘: No such file or directory [root@testserver linuxStudy]# mkdir -p dir4/dir5 #-p:上层目录不存在时,同步创建 [root@testserver linuxStudy]# ls -R #-R:递归列出当前目录下所有的目录、文件 .: dir1 dir2 dir3 dir4 ./dir1: ./dir2: ./dir3: ./dir4: dir5 ./dir4/dir5: [root@testserver linuxStudy]#
例5:-v参数,对于每个创建的目录,打印一条信息
[root@testserver linuxStudy]# mkdir -v dir6 mkdir: created directory `dir6‘ [root@testserver linuxStudy]# mkdir -v dir7 dir8 mkdir: created directory `dir7‘ mkdir: created directory `dir8‘
例6.-m参数,创建目录的同时设置文件权限(同chmod命令)
[root@testserver linuxStudy]# mkdir -m o-rw dir10 #创建dir10目录,other用户去掉rw权限 [root@testserver linuxStudy]# ll total 36 drwxr-xr-x 2 root root 4096 May 9 14:47 dir1 drwxrwx--x 2 root root 4096 May 9 15:08 dir10 drwxr-xr-x 2 root root 4096 May 9 14:47 dir2 drwxr-xr-x 2 root root 4096 May 9 14:47 dir3 drwxr-xr-x 3 root root 4096 May 9 14:52 dir4 drwxr-xr-x 2 root root 4096 May 9 15:02 dir6 drwxr-xr-x 2 root root 4096 May 9 15:02 dir7 drwxr-xr-x 2 root root 4096 May 9 15:02 dir8 drwxrwxrwx 2 root root 4096 May 9 15:07 dir9 [root@testserver linuxStudy]# mkdir -m 511 dir11 #创建dir11目录,设置user、group、other用户权限分别为5、1、1(读权限4,写权限2,执行权限1,用户具备多种权限时值相加) [root@testserver linuxStudy]# ll total 40 drwxr-xr-x 2 root root 4096 May 9 14:47 dir1 drwxrwx--x 2 root root 4096 May 9 15:08 dir10 dr-x--x--x 2 root root 4096 May 9 15:09 dir11 drwxr-xr-x 2 root root 4096 May 9 14:47 dir2 drwxr-xr-x 2 root root 4096 May 9 14:47 dir3 drwxr-xr-x 3 root root 4096 May 9 14:52 dir4 drwxr-xr-x 2 root root 4096 May 9 15:02 dir6 drwxr-xr-x 2 root root 4096 May 9 15:02 dir7 drwxr-xr-x 2 root root 4096 May 9 15:02 dir8 drwxrwxrwx 2 root root 4096 May 9 15:07 dir9
【帮助文档】
Linux环境下输入 man mkdir,查看find命令的帮助文档(ps:英文渣渣咬咬牙啃一啃帮助文档。不要偷懒,多看官方文档。注释部分为个人添加。)
