NAME
       mkdir - Makes a directory

SYNOPSIS
       mkdir [-m mode] [-p] directory...

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       mkdir:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS
       Sets  the file permissions to mode, a symbolic mode string as defined for chmod, after creating the specified directory.  The mode argument
       can be either an absolute mode string or a symbolic mode string as defined for chmod.  See the chmod(1) reference page.

	      In symbolic mode strings, the operation characters + and - are interpreted relative to an assumed initial mode of a=rwx,	A  +  adds
	      permissions  to the default mode, whereas a - deletes permissions from the default mode.	Creates intermediate directories as neces-
	      sary; otherwise, the full path name prefix to directory must already exist.  The user must have mkdir write permission in the parent
	      directory.

	      Each  component  of  directory  that does not name an existing directory is created with mode 777, modified by the current file mode
	      creation mask (umask).  The equivalent of chmod u+wx is performed on each component to ensure that mkdir can create  lower  directo-
	      ries  regardless of the setting of umask. Each component of directory that names an existing directory is ignored without error.	If
	      an intermediate path name component exists, but permissions are set to prevent writing or searching,  mkdir  fails  and  returns	an
	      error message. The mode argument does not apply to any intermediate directories created when the -p option is specified.

OPERANDS
       The path name of the directory to be created.

DESCRIPTION
       The  mkdir  command  creates  new directories with read, write, and execute permissions based upon the permissions established by the umask
       setting.

       [Tru64 UNIX]  The mkdir command also creates the standard entries (dot) for the directory itself and (dot dot) for its parent.

NOTES
       Some of the requested directories may be created although an error occurs subsequent to the directory creation.	If the directory specified
       by  the	-p  option  already  exists, the command does not return an error status, in compliance with POSIX.2.  [Tru64 UNIX]  To make a new
       directory, you must have write permission in the parent directory.

EXIT STATUS
       The following exit values are returned: All requested directories were created, or the -p option was used and all of the requested directo-
       ries now exist.	An error occurred.

EXAMPLES
       To  create  a new directory called test, enter: mkdir test To set file permissions for new directory test in absolute mode, enter: mkdir -m
       444 test To set file permissions for new directory test in symbolic mode, enter: mkdir -m+rw test

ENVIRONMENT VARIABLES
       The following environment variables affect the execution of mkdir: Provides a default value for the internationalization variables that are
       unset or null. If LANG is unset or null, the corresponding value from the default locale is used.  If any of the internationalization vari-
       ables contain an invalid setting, the utility behaves as if none of the variables had been defined.  If set to a  non-empty  string  value,
       overrides  the  values of all the other internationalization variables.	Determines the locale for the interpretation of sequences of bytes
       of text data as characters (for example, single-byte as opposed to multibyte characters in arguments).  Determines the locale for the  for-
       mat  and  contents  of  diagnostic messages written to standard error.  Determines the location of message catalogues for the processing of
       LC_MESSAGES.
