One Linux command per day (4): mkdir

1. Introduction to Commands

mkdir (Make directory creates a directory): Creates a directory if the specified directory does not exist. When you create a directory, you are asked to write permissions for the user who created the directory, and you should ensure that the new directory does not have duplicate names.

2. Usage

Usage:mkdir [options] ... Directory...

3. Options

-M,--mode= mode       Sets the permission mode (similar to chmod) instead of rwxrwxrwx minus umask-p, whereparents        creates the upper-level directory of the target directory when needed, But even if these directories already exist and are not treated as error -V,--verbose        displays information every time a new directory is created -Z,--context=ctx      sets the SELinux security environment for each directory created to CTX

4. Instance 1: Create an empty directory

mkdirlsdir1

Example 2: Create multiple catalogs at once

mkdirlsdir1  dir2  dir3

Example 3: Creating Multiple directories recursively

mkdir -P dir1/sub1/sub2[[email protected] study]# tree.└──dir1    └──sub1        └──sub23  0 files

Example 4: Create a directory with permissions of 755

mkdir 755  lsdrwxr24096 April  : Dir1

Example 5: Creating a new directory displays information

mkdir -v dir3mkdir"dir3"

Example 6: A command to create a directory structure for a project
