Linux mkdir Command: Create Directories and Subdirectories

The mkdir command in Linux creates one or more directories under the current directory. You need write permissions on the directory to execute mkdir.

The most frequent options are:

• -p: Creates the specified directory even if the parent directory does not exist. In this case, it also creates the parent directory;
• -m: Sets the permission of the created directory. The possible permissions are rxwrxwrxw (we will see more later).
• Examples:

Creates the documentos directory:

$ mkdir documentos

Creates the cartas directory under the documentos directory. If documentos does not exist, it creates it first before cartas:

$ mkdir –p documentos/cartas

Creates the modelos directory under the documentos directory with read, write, and execute permissions for the directory owner, its group, and other users:

$ mkdir –m 777 documentos/modelos
