NAME

mkdir − Makes a directory

SYNOPSIS

mkdir [-m mode] [-p] directory ... 

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

FLAGS

-m modeSets 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.  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. 

-pCreates intermediate directories as necessary; otherwise, the full pathname prefix to directory must already exist.  Note that mkdir requires write permission in the parent directory for users other than root.  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 component of directory that names an existing directory is ignored without error, except for the last component.  If an intermediate pathname 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 flag is specified.  Note that if the directory specified by the -p flag already exists, the command fails with a message to the user, but does not return an error status, in compliance with POSIX.2. 

DESCRIPTION

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

EXAMPLES

     1.To create a new directory called test, enter:

mkdir test

     2.To set file permissions for new directory test in absolute mode, enter:

mkdir -m 444 test

     3.To set file permissions for new directory test in symbolic mode, enter:

mkdir -m+rw test

NOTES

To make a new directory, you must have write permission in the parent directory.
