mkdir(1)							      mkdir(1)

       mkdir - Makes a directory

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

       Interfaces  documented on this reference page conform to industry stan‐
       dards as follows:

       mkdir:  XCU5.0

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

       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  per‐
	      missions	from  the default mode.	 Creates intermediate directo‐
	      ries as necessary; 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 directories regardless of the setting of umask. Each  com‐
	      ponent  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.

       The path name of the directory to be created.

       The mkdir command creates new directories with read, write, and execute
       permissions  based  upon	 the permissions established by the umask set‐

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

       Some  of	 the  requested	 directories  may be created although an error
       occurs subsequent to the directory creation.  If the  directory	speci‐
       fied  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.

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

       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

       The following environment variables affect the execution of mkdir: Pro‐
       vides  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, over‐
       rides 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	multi‐
       byte  characters	 in  arguments).  Determines the locale for the format
       and contents of diagnostic messages written to standard error.	Deter‐
       mines  the location of message catalogues for the processing of LC_MES‐

       Commands:  chmod(1), rm(1), rmdir(1), Bourne shell sh(1b), POSIX	 shell
       sh(1p), umask(1)
