Press Ctrl Shift U (Windows/Linux) or Cmd Shift U (macOS) to open the output panel; 2. You can also open the "Switch Output" command in the view menu or command panel; 3. Use the drop-down menu in the upper right corner to switch different output sources such as extensions, Git, tasks, etc.; 4. Use this panel when debugging extension problems, viewing task results, checking Git operations, or troubleshooting startup failures; 5. You can efficiently utilize panel information by clearing logs, enabling automatic scrolling, copying content, etc.; 6. Some logs are only displayed when VS Code starts, and the panel needs to be opened in advance to diagnose problems; 7. The output panel is a key tool for viewing VS Code background information, and is of great value when problems occur.
The Output panel in VS Code is a useful tool for viewing logs, debugging information, and messages from various extensions and built-in features like the integrated terminal, Git, or language servers. Here's how to use it effectively.

How to Open the Output Panel
You can open the Output panel in several ways:
- Press
Ctrl Shift U
(Windows/Linux) orCmd Shift U
(macOS). - Click on View in the top menu, then select Output .
- Use the Command Palette (
Ctrl Shift P
orCmd Shift P
) and type "Toggle Output" to find and run the command.
Once opened, the panel appears at the bottom of the editor, usually grouped with the Terminal, Debug Console, and Problems panel.

Understanding the Output Panel Contents
The Output panel doesn't just show one stream of data — it displays output from different sources, and you can switch between them using a dropdown menu in the top-right corner of the panel.
Common output channels include:

- Extensions (eg, Python, Pylance, ESLint)
- Git
- Tasks
- TypeScript
- JavaScript
- Log (Window) – internal VS Code logs
- Log (Extension Host) – logs from running extensions
- Log (Renderer) – frontend/UI logs
For example, if you're working on a Python project and have the Python extension installed, you might see logs related to linting, formatting, or IntelliSense initialization under the "Python" channel.
When and Why to Use the Output Panel
You'll typically use the Output panel in these situations:
- Debugging extension issues : If an extension isn't working (eg, autocomplete stops), check its output for error messages.
- Viewing task results : After running a build task, the output shows compilation results or errors.
- Checking Git operations : Some Git actions (like sync or rebase) may log detailed info here.
- Troubleshooting startup problems : If VS Code or an extension fails to activate, the "Log (Extension Host)" can reveal why.
For instance, if your ESLint isn't highlighting errors, switching to the "ESLint" output channel might show that it failed to find a configuration file.
Tips for Using the Output Panel Effectively
- Clear output : Click the trash icon in the panel to clear old logs and focus on new messages.
- Auto-scroll : The panel automatically scrolls to the latest message unless you manually scroll up. Click the scroll lock icon to toggle this.
- Copy content : You can select and copy text from the output (eg, to search an error online).
- Monitor during startup : Some logs only appear when VS Code starts, so open the Output panel early if diagnosed launch issues.
It's also helpful to know that some extensions only log information when things go wrong — others provide verbose logs by default.
Basically, the Output panel is your go-to place for behind-the-scenes info in VS Code. While you don't need it every day, it's invaluable when something isn't working as expected.

There are three ways to change the default terminal in VSCode: setting through a graphical interface, editing settings.json file, and temporary switching. First, open the settings interface and search for "terminalintegratedshell" and select the terminal path of the corresponding system; secondly, advanced users can edit settings.json to add "terminal.integrated.shell.windows" or "terminal.integrated.shell.osx" fields and escape the path correctly; finally, you can enter "Terminal:SelectD through the command panel

1. Confirm whether the command is installed 2. Check the terminal shell type 3. Update the PATH environment variable 4. Restart VSCode or terminal. When you enter a command in the VSCode terminal, you should first check whether the command has been installed correctly and can be verified through other terminals of the system; secondly, confirm the shell type used by VSCode and check its configuration file; then make sure that the path where the command is located has been added to the PATH environment variable, and manually add and reload the configuration if necessary; finally close and reopen the terminal or restart VSCode to make the changes take effect.

When the "Timedoutwaitingforthedebuggertoattach" issue occurs, it is usually because the connection is not established correctly in the debugging process. 1. Check whether the launch.json configuration is correct, ensure that the request type is launch or attach and there is no spelling error; 2. Confirm whether the debugger is waiting for the debugger to connect, and add debugpy.wait_for_attach() and other mechanisms; 3. Check whether the port is occupied or firewall restricted, and replace the port or close the occupied process if necessary; 4. Confirm that the port mapping and access permissions are configured correctly in a remote or container environment; 5. Update VSCode, plug-in and debug library versions to solve potential

VSCode workspace is a .code-workspace file that saves project-specific configurations. 1. It supports multi-root directory, debug configuration, shortcut key settings and extension recommendations, and is suitable for managing different needs of multiple projects. 2. The main scenarios include multi-project collaboration, customized development environment and team sharing configuration. 3. The creation method is to save the configuration through the menu File>SaveWorkspaceAs.... 4. Notes include distinguishing between .code-workspace and .vscode/settings.json, using relative paths, and avoiding storing sensitive information.

There are two ways to set environment variables for VSCode terminals on Linux: one is to use the terminal.integrated.env.linux configuration item to define variables that are only used by VSCode; the other is to modify the shell configuration file to take effect globally. 1. In VSCode, add variables such as "MY_VAR":"my_value" by setting the terminal.integrated.env.linux field. This method only affects the VSCode terminal; 2. Modify shell configuration files such as ~/.bashrc or ~/.zshrc and add exportMY

To set debug environment variables in VSCode, you need to use the "environment" array configuration in the launch.json file. The specific steps are as follows: 1. Add "environment" array to the debugging configuration of launch.json, and define variables in key-value pairs, such as API_ENDPOINT and DEBUG_MODE; 2. You can load variables through .env files to improve management efficiency, and use envFile to specify file paths in launch.json; 3. If you need to overwrite the system or terminal variables, you can directly redefine them in launch.json; 4. Note that

To access the settings.json file of VSCode, you can directly open it through the command panel (Ctrl Shift P or Cmd Shift P). The default storage location of the file varies according to the operating system. Windows is in %APPDATA%\Code\User\settings.json, macOS is in $HOME/Library/ApplicationSupport/Code/User/settings.json, Linux is in $HOME/.config/Code/User/

Enable Git automatic pull (autofetch) in VSCode needs to be implemented by configuring Git and VSCode settings. 1. Configure Git to remotely get all branches: execute gitconfig --globalremote.origin.fetch "refs/heads/*:refs/remotes/origin/*". 2. Turn on automatic fetch in VSCode: Set "git.autofetch":true to execute gitfetch regularly. 3. Optional installation extensions such as GitLens or AutoFetchforGit are more powerful
