MKDIR(C) UNIX System V
Name
mkdir - makes a directory
Syntax
mkdir [ -m mode ] [ -p] dirname ...
Description
The mkdir command creates the named directories in mode 777
[possibly altered by umask(C)].
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(C).
-p With this option, mkdir creates dirname by creating all
the non-existing parent directories first.

Diagnostics
The mkdir command returns exit code 0 if all directories
given in the command line were made successfully.
Otherwise, it prints a diagnostic and returns non-zero. An
error code is stored in errno.

mkdir is conformant with:
