mkdir

Command Function

This command is used to create a directory.

Syntax

mkdir [-vp] [-m mode] [dirname…]

Parameters

Table 1 Parameter description

Parameter	Description
–help	Displays the parameters supported by the mkdir command.
-m	Sets the permissions on the directory to create.
-p	Creates parent and child directories recursively.
-v	Prints detailed information about the directory creation process.
directory	Specifies the directory to create.

Usage Guidelines

For the files created on the FAT file system, the file permission attributes are the same as those of the mounted nodes. Currently, the node permissions include only user read and write. The group and others permissions do not take effect.

In addition, only the user read and write permissions can be modified. The read and write permissions are rw and ro only. Therefore, when the -m option is specified in the mkdir command, only 777 and 555 permissions are available for the created directory, and the execute permission does not take effect.

Note

Currently, the shell does not support this command. mksh supports it. To switch to mksh, run cd bin and ./mksh.

Example

Run the following commands:

mkdir testpath
mkdir -m 777 testpath
mkdir -pv testpath01/testpath02/testpath03

Output

Example 1: Create a directory named testpath.

OHOS:/tmp$ mkdir testpath
OHOS:/tmp$ ll
total 2
drwxrwxrwx 1 0 0 2048 1979-12-31 00:00 testpath/

Example 2: Create a directory named testpath with specified permissions.

OHOS:/tmp$ mkdir -m 777 testpath
OHOS:/tmp$ ll
total 2
drwxrwxrwx 1 0 0 2048 1979-12-31 00:00 testpath/

Example 3: Create directories recursively.

OHOS:/tmp$ mkdir -pv testpath01/testpath02/testpath03
mkdir: created directory 'testpath01'
mkdir: created directory 'testpath01/testpath02'
mkdir: created directory 'testpath01/testpath02/testpath03'
OHOS:/tmp$ ll
total 2
drwxrwxrwx 1 0 0 2048 1979-12-31 00:00 testpath01/
OHOS:/tmp$ ll testpath01/
total 2
drwxrwxrwx 1 0 0 2048 1979-12-31 00:00 testpath02/
OHOS:/tmp$ ll testpath01/testpath02/
total 2
drwxrwxrwx 1 0 0 2048 1979-12-31 00:00 testpath03/
