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 directory.

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 intermedi-
		       ate directories will be the difference between 777 and the bits set in the file mode creation mask.  The  difference,  how-
		       ever, 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.

USAGE

       See largefile(5) for the description of the behavior of mkdir when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

EXAMPLES

       Example 1: Using mkdir

       The following example:

       example% mkdir -p ltr/jd/jan

       creates the subdirectory structure ltr/jd/jan.

ENVIRONMENT VARIABLES

       See  environ(5) for descriptions of the following environment variables that affect the execution of mkdir: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	All the specified directories were created successfully or the -p option was specified	and  all  the  specified  directories  now
		exist.

       >0	An error occurred.
