To keep VSCode's theme settings consistent on multiple Linux machines, you can use the following three methods: 1. Use the built-in GitHub account synchronization function of VSCode, synchronize upload configurations through File > Preferences > Enable settings, and log in to the same GitHub account to download on other devices; 2. Manually copy the settings.json file (the path is ~/.config/Code/User/settings.json) to overwrite the corresponding files of the target device; 3. Create a dotfiles repository for version control, add the configuration file to the Git library and create symbolic links on each device to point to the file. These three methods are applicable to different needs, from automatic synchronization to fine control.
If you use VSCode across multiple Linux machines and want to keep your theme settings consistent, there are practical ways to do it without manually copying everything every time. The key is leveraging built-in features or simple tools that streamline the process.

Use VSCode Settings Sync (Built-in GitHub Account Sync)
VSCode has a built-in Settings Sync feature that uses your GitHub account to sync themes, extensions, settings, and more across devices.

- Sign in with your GitHub account via
File > Preferences > Turn on Settings Sync
- Once enabled, your current settings—including the active theme—are uploaded to the cloud
- On another machine, just sign in with the same account and download the synched data
This works great if you're OK with storing your preferences on GitHub. It's seamless and requires no manual file handling.
Manually Copy the settings.json
File
If you prefer full control or don't want to use cloud synchronization, you can manually copy your VSCode configuration files between machines.

The main file for theme and appearance settings is located at:
~/.config/Code/User/settings.json
To sync it:
- Copy this file from your source machine
- Paste it into the same location on the target machine
- Restart VSCode
Note: This will overwrite any local settings on the destination machine, so be careful when replacing it.
You may also want to check:
-
~/.config/Code/User/keybindings.json
(for custom keyboard shortcuts) -
~/.config/Code/User/globalStorage/state.vscdb
(some UI state info)
Use a Dotfiles Repository for Better Control
For developers who like managing config files systematically, setting up a dotfiles repo is a solid long-term solution.
Here's how it works:
- Create a Git repository (eg, on GitHub) for your config files
- Add your VSCode settings files to it
- On each machine, clone the repo and create symbolic links to the config folder
Example commands:
ln -sf ~/dotfiles/vscode/settings.json ~/.config/Code/User/settings.json
This method gives you version control, easy updates, and a way to back up all your dev environment preferences in one place.
That's basically how you can keep your VSCode theme and settings aligned across Linux systems. Whether you go for the built-in sync or a manual/dotfiles approach depends on how much control you want and how often you switch machines.

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

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

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

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.

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/

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

In VSCode, you can disable specific extensions by configuring .vscode/extensions.json and workspace settings. The specific steps are as follows: 1. Create or edit the .vscode/extensions.json file and add "ignoreRecommendations":true to ignore global recommendations; 2. Use the "recommendations" field in this file to specify only enabled extensions; 3. Open the workspace settings.json file and add configuration items such as "eslint.enable":false to disable support
