Creates one or more new directories.
mkdir [ -m Mode ] [ -p ] Directory ...
The mkdir command creates one or more new directories specified by the Directory parameter. Each new directory contains the standard entries . (dot) and .. (dot-dot). You can specify the permissions for the new directories with the -m Mode flag. You can use the umask subroutine to set the default mode for the mkdir command.
Note: To make a new directory you must have write permission in the parent directory.
-m Mode | Sets the permission bits for the newly-created directories to the value specified by the Mode variable. The Mode variable takes the same values as the Mode parameter for the chmod command, either in symbolic or numeric form.
When you specify the -m flag using symbolic format, the op characters + (plus) and - (minus) are interpreted relative to the assumed permission setting a=rwx. The + adds permissions to the default mode, and the - deletes permissions from the default mode. Refer to the chmod command for a complete description of permission bits and formats. |
-p | Creates missing intermediate path name directories. If the -p flag is not specified, the parent directory of each-newly created directory must already exist.
Intermediate directories are created through the automatic invocation of the following mkdir commands: mkdir -p -m $(umask -S),u+wx $(dirname Directory) && mkdir [-m Mode] Directory where the [-m Mode ] represents any option supplied with your original invocation of the mkdir command. The mkdir command ignores any Directory parameter that names an existing directory. No error is issued. |
This command returns the following exit values:
0 | All the specified directories were created successfully, or the -p option was specified and all the specified directories now exist. |
>0 | An error occurred. |
mkdir TestThe Test directory is created with default permissions.
mkdir -m 755 /home/demo/sub1/Test
mkdir -p /home/demo/sub2/TestThe -p flag creates the /home , /home/demo , and /home/demo/sub2 directories if they do not already exist.
/usr/bin/mkdir | Contains the mkdir command. |
The chmod command, rm command.
The mkdir subroutine, umask subroutine.
