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 direc-
tory.
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 intermediate directories will be
the difference between 777 and the bits set in the
file mode creation mask. The difference, however,
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.
EXAMPLES
The following example:
example% mkdir -p ltr/jd/jan
creates the subdirectory structure ltr/jd/jan.
