Windows Command Prompt (命令提示字元)

  • To open Command Prompt in Windows: Press the Windows key, type cmd, and press the Enter key.
  • Use the Tab key to complete folder/file names.
  • Use <command> /? to know how to use the specific command

Common Command Line Commands

CMD Commands Linux/Mac commands Description
dir ls -l Listing Directory
cd cd Change Directory
del rm Delete Files
mkdir mkdir Create a directory
move mv Move a file/Rename a file
cls clean Clear the screen
rmdir rmdir Remove an empty directory
type cat Displays the contents of a text file
copy cp Copy one or multiple files from one location to another
find grep Search for a string in a file
fc diff-19 File compare

Example

dir

C:\Users\user>dir

C:\Users\user>dir <FolderName>

C:\Users\user>dir <String>*  # list all files in the current directory that begin with <String>

cd

C:\Users\user>cd <FolderName>

C:\Users\user\Music>cd ..  # back to the parent directory

C:\Users\user>cd "<FolderName with Spaces>"  # double quotes for spaces in folder name

C:\Users\user>cd ../..   # back to the directory two levels above

C:\Users\user>cd <Absolute Path>

del

C:\Users\user>del <File>

mkdir

C:\Users\user>mkdir <New FolderName>

move

C:\Users\user>move <Files> <Destination>  # Move files

C:\Users\user>move <Old FileName> <New Filename>  # Rename files

cls

C:\Users\user>cls

rmdir

C:\Users\user>rmdir <FolderName>  # for an empty folder

C:\Users\user>rmdir /s <FolderName>  # for the folder with other files inside

C:\Users\user>rmdir /s /q <FolderName>  # delete folder without asking

# Python Fundamentals

This folder contains all the downloadable materials for my Udemy **Python Fundamentals** course, available here:

[https://www.udemy.com/course/python3-fundamentals](https://www.udemy.com/course/python3-fundamentals/?referralCode=DA09C6F40CEC38C942F6)

This folder is organized into the various sections of the course, and those themselves are organized by lesson within each chapter.


Resources include:

- Fully annotated Jupyter notebooks corresponding to the coding lessons.
- Any files we used during the coding lessons.
- Exercises for each chapter containing at least two files:
        - A Jupyter notebook with the questions.
        - A second Jupyter notebook with a fully annotated solution (you may have a different way of solving the problem and that's absolutely fine, as long as your code works, and is clear and easy to read).
        - if applicable, additional data files or materials needed to complete the exercises.


In the first chapter of this course I explain how to install and run Jupyter notebooks - please refer to that chapter if you need detailed instructions.
