Create 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.
Set the access mode for new directories. See chmod for an explanation of acceptable formats for mode.
Create intervening parent directories if they don’t exist.
Print a message for each directory created.
Print help message and then exit.
Print version number and then exit.
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
