The mkdir command in Linux and Unix-like systems stands for “make directory”. It is used to create a new directory.

Here is the basic syntax for the mkdir command:

mkdir [options] directory_name

directory_name is the name of the directory you want to create.

$ mkdir mydirectory

Remember that you can check your current working directory by using the pwd command.

2. to create a new directory called “mail-backup” in the home directory:

$ mkdir ~/mail-backup

Notice the ~/ in front of the mail-backup

3. There is a way to create multiple directories at once:

$ mkdir directory1 directory2 directory3

4. To create a directory and all its parent directories if they do not exist:

$ mkdir -p /full/path/to/new/directory

5. To create a directory with permissions:

$ mkdir -m 777 mydirectory
