How to use the Windows command line (DOS)

To use the Windows command line (DOS), follow these steps:

  1. Open the command prompt: Click on the “Start” menu, type “cmd” in the search bar, and press enter. Alternatively, you can press the Windows key + R to open the “Run” dialog box, type “cmd” and press enter.
  2. Navigate to the directory where you want to execute the command: Use the “cd” command followed by the path to the directory you want to navigate to. For example, to navigate to the “Documents” folder on your C drive, type “cd C:\Users\yourusername\Documents” and press enter.
  3. Enter a command: Type the command you want to execute and press enter. For example, to list the contents of the current directory, type “dir” and press enter.
  4. Review the output: The output of the command will be displayed in the command prompt window. If there is a lot of output, you can use the scroll bar on the right side of the window to scroll up and down.
  5. Repeat steps 2-4 as necessary: You can navigate to different directories and execute different commands as needed.
  6. Exit the command prompt: When you are finished using the command prompt, type “exit” and press enter to close the window.

Some common commands you can use in the Windows command line include “dir” to list the contents of a directory, “cd” to change the current directory, “mkdir” to create a new directory, “type” to display the contents of a file, “copy” to copy files, and “del” to delete files. You can use the “help” command to see a list of all available commands, and you can use the “/?” switch with a command to see the syntax and options for that command.
