可以通過終端在Linux中更新所有VSCode擴展，具體步驟如下：1. 檢查code是否在PATH中，運行which code確認路徑；2. 列出已安裝的擴展，使用code --list-extensions獲取擴展ID；3. 逐一更新擴展，執(zhí)行code --list-extensions | xargs -L 1 code --install-extension --force命令；4. 可選跳過不可用擴展，使用腳本code --list-extensions | while read ext; do code --install-extension "$ext" --force || echo "Failed to update: $ext"; done實現(xiàn)。

Updating all Visual Studio Code (VSCode) extensions through the terminal in Linux isn’t something the app supports directly out of the box — but there’s a practical way to do it using a few commands and tools.

Check if code is in your PATH

Before doing anything, make sure the code command is available in your terminal. You can test this by running:

which code

If it returns something like /usr/bin/code, you're good. If not, you might need to install VSCode properly or create a symlink manually. Once that's confirmed, you can proceed.

List all installed extensions

To update all extensions, you first need to know what’s installed. Run this command to list them:

code --list-extensions

This will output a list of extension IDs like:

ms-python.python
esbenp.prettier-vscode
dbaeumer.vscode-eslint

These IDs are needed for updating each extension individually.

Update all extensions one by one

Since VSCode doesn’t have a built-in "update all" command, you can combine the above with a loop in your shell. Here’s how to do it in Bash:

code --list-extensions | xargs -L 1 code --install-extension --force

Let’s break down what this does:

• code --list-extensions: gets the list of installed extensions.
• xargs -L 1: runs the next command once per line.
• code --install-extension --force: reinstalls the extension, which effectively updates it if a newer version exists.

You’ll see VSCode downloading and reinstalling each extension. It may take a minute or two depending on how many you have.

Optional: Automatically skip outdated or unavailable extensions

Sometimes, an extension might no longer be available or cause issues during the update. To skip those without stopping the whole process, wrap the update in a small script:

code --list-extensions | while read ext; do
  code --install-extension "$ext" --force || echo "Failed to update: $ext"
done

This will try to update each extension and print a message if one fails, instead of stopping everything.

That’s basically it

It’s not the smoothest workflow, but it works reliably. If you find yourself doing this often, consider wrapping it into a shell script or alias for easier reuse.
