About mkdir

The mkdir command creates new directories in your file system.


mkdir [-m=mode] [-p] [-v] [-Z=context] directory [directory ...]
mkdir --version
mkdir --help


directory The name of the directory to be created. If the specified directory does not already exist, mkdir creates it. More than one directory may be specified.

A specified directory can include path information. For instance, if the current directory is /home/hope, and you'd like to create the directory /home/hope/Documents/writing, you can use the command mkdir Documents/writing. If the Documents folder does not already exist, you should specify the -p option to create it automatically, otherwise the command will fail.
You can use the -m option to set a file mode (permissions, etc.) for the created directories. The syntax of mode is the same as with the chmod command.
Create parent directories as necessary. When this option is specified, no error is reported if a directory already exists.
Verbose output. Print a message for each created directory.
If you are using SELinux, this option sets the security context of each created directory to context. For detailed information about security contexts, consult your SELinux documentation.
--help Display a help message, and exit.
--version Display version information, and exit.

Exit status

mkdir returns an exit status of zero if all operations were successful, or a non-zero exit status if operations failed.


mkdir myfiles

Create a new directory called myfiles in the current directory.

mkdir ~/myfiles

Create the directory myfiles in your home directory, specified here with a tilde ("~"). For more information about using ~ to represent your home directory, see tilde expansion in bash.

mkdir -m a=rwx mydir

Create the mydir directory, and set its file mode (-m) so that all users (a) may read (r), write (w), and execute (x) it.

For directories, this means that any user on the system may view ("read"), and create/modify/delete ("write") files in the directory. Any user may also change to ("execute") the directory, for example with the cd command.

chdir -m 777 mydir

Same as the above command, but using a numerical file mode. Grants read, write, and execute permissions to the directory for all users. (For more information about file modes, see chmod).

mkdir -p /home/hope/Documents/pdf

Creates the directory /home/hope/Documents/pdf. If any of the parent directories /home, /home/hope, or /home/hope/Documents do not already exist, they will automatically be created.

rmdir — Remove a directory.
