在React.js项目的终端中出现“1:powershell”字样的原因是什么？

Hey there! Let me walk you through the common reasons you're seeing that 1:powershell label pop up in your terminal while working on React projects:

• Terminal Session Numbering
  Most modern terminal tools (like VS Code's integrated terminal, Windows Terminal, or IDE-built-in terminals) assign a unique number to each new terminal session you open. The 1 here simply means this is the first active terminal session, and :powershell tells you that this session is using the PowerShell shell environment. If you open a second terminal tab/window, you might see 2:powershell (or another shell name if you switch to CMD/WSL).

• Task/Process Identifier
  When you run React scripts (like npm start to launch the development server), some terminal or task-running tools attach this label to help you quickly identify which terminal is handling your React dev process. It’s a handy way to distinguish between a terminal running your dev server, one where you’re installing dependencies, and another where you’re running test scripts.

• Default Terminal Configuration
  Many terminals come with a default setting to display the session number and current shell type. This is designed to reduce confusion when you’re juggling multiple terminal environments—for example, if you switch between PowerShell, WSL Ubuntu, and CMD, this label makes it instantly clear which environment you’re working in at a glance.

If you find the label distracting, you can usually tweak your terminal’s settings to hide it. For example, in VS Code, you can adjust the terminal.integrated.tabs.title setting to customize what’s displayed in terminal tabs.
