There are basically five Linux directory commands that are used to WORK with FILES and directories as given below: 

• PWD: It stands for “print working directory”. This COMMAND is generally used to DISPLAY the path of the present or current working directory.

  Syntax: $ cd <path to new directory> 
• Is: It stands for “list”. This command is generally used to show the full list of content of files and directories in the present working directory. 
  Syntax: $ ls 
• mkdir: It stands for “make directory”. This command generally allows users to create directories in Linux.  
  Syntax: $ mkdir <name (and path if required) of new directory>
