VSCode code Command

In Visual Studio Code, the code command is a command-line tool used to quickly open VS Code and perform some code-related operations.

The code command directly helps developers launch VS Code from the terminal or command prompt, or handle specific tasks.

The most common way is to usecodethe command to directly open a file directory from the command line. At this point, you need to install the code command first.

After installing VS Code on Windows, the code command is automatically registered in the system environment variables. If it is not registered, you can manually add the VS Code installation path to the PATH environment variable.

Enabling the VSCode code command is very simple. First, open the command palette:

macOS system shortcut keys:⇧⌘P（command + shift + p）
Windows/Linux shortcut keys:Ctrl + Shift + P

Search install >shell command:

Then selectInstall the 'code' command in PATH - Shell Command: Install 'code' command in PATHThis will add thecodecommand reference to the system PATH.

We can open files, install extensions, change the display language, and even view diagnostic information through the command line.

The following are some commonly used command-line options, which can be viewed through thecode --helpcommand:

We can use thecode .command in the command line to open a folder in VS Code:

Command	Function Description
`code <路径>`	Open a file or folder
`code .`	Open the current directory as a workspace
`code --new-window`	Open in a new window
`code --diff`	Compare the contents of two files
`code --wait`	Wait for the window to close before returning to the terminal
`code --disable-extensions`	Run VS Code with all extensions disabled
`code --install-extension <扩展名>`	Install a specified extension
`code --list-extensions`	List all installed extensions
`code --uninstall-extension <扩展名>`	Uninstall a specified extension

Common Functions of the code Command

1. Open a file or folder

code <文件路径>

For example, open the app.js file:

code app.js

Open a folder (as a workspace):

code <文件夹路径>

For example, open the my-project folder:

code my-project

2. Create a new file

If the specified file does not exist, code will create the file and open it:

code newfile.js

3. Open VS Code with the current directory as the workspace

Running the code command directly will start VS Code with the directory where the current terminal is located as the workspace:

code .

4. Compare files

The code command supports file content comparison:

code --diff <文件1> <文件2>

Example:

code --diff index.html index-backup.html

5. View help
