Hey there! Let's tackle your Jupyter Notebook startup questions step by step—super common asks, so I’ve got you covered.

一、从任意所需位置打开Jupyter Notebook #

Here are a few reliable methods depending on your OS:

1. Terminal/Command Line (Cross-Platform) #

This is the most flexible approach that works on Windows, Mac, and Linux:

• Open your terminal (Command Prompt/PowerShell for Windows, Terminal for Mac/Linux)
• Use the cd command to navigate to your target folder, e.g., cd C:\Projects\MyDataNotebooks (Windows) or cd ~/Documents/MachineLearning (Mac/Linux)
• Type jupyter notebook and hit enter—Jupyter will launch directly from this folder, and your browser will show all files in the directory

2. Add Right-Click Option (Windows) #

If you prefer point-and-click over commands, add a permanent right-click menu entry:

• Open Registry Editor (press Win+R, type regedit, hit enter)
• Navigate to HKEY_CLASSES_ROOT\Directory\Background\shell
• Right-click shell, select "New > Key", name it Jupyter Notebook
• Right-click this new key, select "New > Key", name it command
• Double-click the "Default" value in the command key, and paste: "C:\Users\YourUsername\AppData\Local\Programs\Python\PythonXX\Scripts\jupyter-notebook.exe" "%V" (replace YourUsername and PythonXX with your actual info)
• Now right-click any empty space in a folder, and you’ll see a "Jupyter Notebook" option that launches directly from that location

3. Modify Desktop Shortcut (Windows) #

If you already have a Jupyter shortcut on your desktop:

• Right-click the shortcut, select "Properties"
• In the "Start in" field, replace the default path with your preferred folder
• Click "OK"—now double-clicking the shortcut will launch Jupyter from your chosen directory

4. Custom Startup Script (Mac/Linux) #

Create a reusable script to launch from your favorite folder:

• Open a text editor, paste this code (replace the path with your target folder):

  #!/bin/bash
  cd /path/to/your/favorite/folder
  jupyter notebook
  

• Save it as start_jupyter.sh
• In Terminal, run chmod +x start_jupyter.sh to give it execution permissions
• From now on, double-click the script or run ./start_jupyter.sh in Terminal to launch Jupyter from your specified folder

二、仅本次从指定文件夹启动 (No Default Changes) #

If you want a one-time launch from a different folder without altering your default settings, these methods work perfectly:

1. Terminal/Command Line (Quickest) #

• Open your terminal, navigate to the temporary folder using cd /path/to/temp/folder
• Run jupyter notebook—this session will use the temporary folder, and your next normal launch will revert to the default location

2. Temporary Shortcut Edit (Windows) #

• Right-click your Jupyter shortcut, select "Properties"
• Temporarily change the "Start in" field to your desired folder
• Click "OK", launch Jupyter, then go back to Properties and restore the original path (or just close Properties without saving if you didn’t hit "Apply")

3. Direct Path Command (Mac/Linux) #

Skip navigating with cd and launch directly with one command:

jupyter notebook --notebook-dir="/path/to/your/temp/folder"

This launches Jupyter from the specified folder once, with no impact on your default startup location
