Mac OS X in a Nutshell

Name

mkdir

Synopsis

mkdir [options] directories
                  

Creates one or more directories. You must have write permission in the parent directory in order to create a directory. See also rmdir. The default mode of the new directory is 0777, modified by the system or user’s umask.

Options

-m

Set the access mode for new directories. See chmod for an explanation of acceptable formats for mode.

-p

Create intervening parent directories if they don’t exist.

Examples

Create a read-only directory named personal:

                     mkdir -m 444 personal

The following sequence:

                     mkdir work; cd work
                     mkdir junk; cd junk
                     mkdir questions; cd ../..

can be accomplished by typing this:

                     mkdir -p work/junk/questions
