mkdir(1) User Commands mkdir(1)
NAME
mkdir - make directories
SYNOPSIS
mkdir [-m mode] [-p] dir...
DESCRIPTION
The mkdir command creates the named directories in mode 777 (possibly altered by the file mode creation mask umask(1)).
Standard entries in a directory (for instance, the files ".", for the directory itself, and "..", for its parent) are made automatically.
mkdir cannot create these entries by name. Creation of a directory requires write permission in the parent directory.
The owner-ID and group-ID of the new directories are set to the process's effective user-ID and group-ID, respectively. mkdir calls the
mkdir(2) system call.
setgid and mkdir
To change the setgid bit on a newly created directory, you must use chmod g+s or chmod g-s after executing mkdir.
The setgid bit setting is inherited from the parent directory.
OPTIONS
The following options are supported:
-m mode This option allows users to specify the mode to be used for new directories. Choices for modes can be found in chmod(1).
-p With this option, mkdir creates dir by creating all the non-existing parent directories first. The mode given to intermedi-
ate directories will be the difference between 777 and the bits set in the file mode creation mask. The difference, how-
ever, must be at least 300 (write and execute permission for the user).
OPERANDS
The following operand is supported:
dir A path name of a directory to be created.
USAGE
See largefile(5) for the description of the behavior of mkdir when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
EXAMPLES
Example 1: Using mkdir
The following example:
example% mkdir -p ltr/jd/jan
creates the subdirectory structure ltr/jd/jan.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of mkdir: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
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.
