NAME
mkdir - make directories
SYNOPSIS
mkdir [ -m mode ] [ -p] dirname ...
DESCRIPTION
mkdir creates the named directories in mode 777 (possibly altered by
umask(1)).
Standard entries in a directory (e.g., 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
real user ID and group ID, respectively.
Two options apply to mkdir:
-m 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 dirname by creating all the non-
existing parent directories first.
EXAMPLE
To create the subdirectory structure ltr/jd/jan, type:
mkdir -p ltr/jd/jan

DIAGNOSTICS
mkdir returns exit code 0 if all directories given in the command line
were made successfully. Otherwise, it prints a diagnostic and returns
non-zero.
