You can open files, install extensions, change the display language, and output diagnostics through command-line options (switches).

Visual Studio Code has a powerful command line interface built-in that lets you control how you launch the editor. You can open files, install extensions, change the display language, and output diagnostics through command-line options (switches).

  1. Display line numbers in code. On the menu bar, choose Tools Options. Expand the Text Editor node, and then select either the language you're using or All Languages to turn on line numbers in all languages. (Or, type line number in the search box and choose Turn line numbers on or off from the results.) Select the Line numbers checkbox.
  2. This is the core of the code, but what is with all the rest? Lets just say that Module is a piece of the software for now and that a Sub is like a functionality, in that case, the first functionality the computer is going to execute. Visual Basic ' Add this line to the code. Console.ReadKey C# // Add this line to the code.

Command line help

To get an overview of the VS Code command line interface, open a terminal or command prompt and type code --help. You will see the version, usage example, and list of command line options.

Launching from command line

You can launch VS Code from the command line to quickly open a file, folder, or project. Typically, you open VS Code within the context of a folder. To do this, from an open terminal or command prompt, navigate to your project folder and type code .:

Studio

Note: Users on macOS must first run a command (Shell Command: Install 'code' command in PATH) to add VS Code executable to the PATH environment variable. Read the macOS setup guide for help.

Windows and Linux installations should add the VS Code binaries location to your system path. If this isn't the case, you can manually add the location to the Path environment variable ($PATH on Linux). For example, on Windows, VS Code is installed under AppDataLocalProgramsMicrosoft VS Codebin. To review platform specific setup instructions, see Setup.

Source

Insiders: If you are using the VS Code Insiders preview, you launch your Insiders build with code-insiders.

Core CLI options

Here are optional arguments you can use when starting VS Code at the command line via code:

ArgumentDescription
-h or --helpPrint usage
-v or --versionPrint VS Code version (for example, 1.22.2), GitHub commit id, and architecture (for example, x64).
-n or --new-windowOpens a new session of VS Code instead of restoring the previous session (default).
-r or --reuse-windowForces opening a file or folder in the last active window.
-g or --gotoWhen used with file:line[:character], opens a file at a specific line and optional character position. This argument is provided since some operating systems permit : in a file name.
-d or --diffOpen a file difference editor. Requires two file paths as arguments.
-w or --waitWait for the files to be closed before returning.
--locale <locale>Set the display language (locale) for the VS Code session. (for example, en-US or zh-TW)

Opening Files and Folders

Sometimes you will want to open or create a file. If the specified file does not exist, VS Code will create them for you along with any new intermediate folders:

For both files and folders, you can use absolute or relative paths. Relative paths are relative to the current directory of the command prompt where you run code.

If you specify more than one file at the command line, VS Code will open only a single instance.

If you specify more than one folder at the command line, VS Code will create a Multi-root Workspace including each folder.

ArgumentDescription
fileName of a file to open. If the file doesn't exist, it will be created and marked as edited. You can specify multiple files by separating each file name with a space.
file:line[:character]Used with the -g argument. Name of a file to open at the specified line and optional character position. You can specify multiple files in this manner, but you must use the -g argument (once) before using the file:line[:character] specifier.
folderName of a folder to open. You can specify multiple folders and a new Multi-root Workspace is created.

Working with extensions

You can install and manage VS Code extensions from the command line.

ArgumentDescription
--install-extension <ext>Install an extension. Provide the full extension name publisher.extension as an argument. Use --force argument to avoid prompts.
--uninstall-extension <ext>Uninstall an extension. Provide the full extension name publisher.extension as an argument.
--disable-extensionsDisable all installed extensions. Extensions will still be visible in the Disabled section of the Extensions view but they will never be activated.
--list-extensionsList the installed extensions.
--show-versionsShow versions of installed extensions, when using --list-extensions
--enable-proposed-api <ext>Enables proposed api features for an extension. Provide the full extension name publisher.extension as an argument.

Advanced CLI options

There are several CLI options that help with reproducing errors and advanced setup.

ArgumentDescription
--extensions-dir <dir>Set the root path for extensions. Has no effect in Portable Mode.
--user-data-dir <dir>Specifies the directory that user data is kept in, useful when running as root. Has no effect in Portable Mode.
-s, --statusPrint process usage and diagnostics information.
-p, --performanceStart with the Developer: Startup Performance command enabled.
--disable-gpuDisable GPU hardware acceleration.
--verbosePrint verbose output (implies --wait).
--prof-startupRun CPU profiler during startup.
--upload-logsUploads logs from current session to a secure endpoint.
Multi-root
--add <dir>Add folder(s) to the last active window for a multi-root workspace.

Opening VS Code with URLs

You can also open projects and files using the platform's URL handling mechanism. Use the following URL formats to:

Open a project

Open a file

Open a file to line and column

You can use the URL in applications such as browsers or file explorers that can parse and redirect the URL. For example, on Windows, you could pass a vscode:// URL directly to the Windows Explorer or to the command line as start vscode://{full path to file}.

Note: If you are using VS Code Insiders builds, the URL prefix is vscode-insiders://.

Common questions

'code' is not recognized as an internal or external command

Your OS cannot find the VS Code binary code on its path. The VS Code Windows and Linux installations should have installed VS Code on your path. Try uninstalling and reinstalling VS Code. If code is still not found, consult the platform specific setup topics for Windows and Linux.

Visual Studio Project Lines Of Code

On macOS, you need to manually run the Shell Command: Install 'code' command in PATH command (available through the Command Palette⇧⌘P (Windows, Linux Ctrl+Shift+P)). Consult the macOS specific setup topic for details.

How do I get access to a command line (terminal) from within VS Code?

VS Code has an Integrated Terminal where you can run command-line tools from within VS Code.

Can I specify the settings location for VS Code in order to have a portable version?

Not directly through the command line, but VS Code has a Portable Mode which lets you keep settings and data in the same location as your installation, for example, on a USB drive.

I found it quite odd to discover that there was no built in method to count the total amount of lines for a project in Visual Studio 2013. I did some searching and found that pretty much every guide was saying download this application or install this plugin in order to get the code metrics. This is a big waste when all you want to see is what the total lines of code in your solution is. Thankfully there is a really simple solution to find out how many lines of code there are in your project. Here is how to get the total line count in visual studio 2013.

Open up your project solution and press CTRL + SHIFT + F. This will open the typical find and replace / search window. Go down to the “Find Options” field and open the drop down. Go down and select the “Use Regular Expressions” box. This will allow you to perform a search using regex. In the “Find what:” box, enter the following value.

Click the “Find All” button and Visual Studio will begin counting all of the lines of code. The more lines the longer this will take, but once it has been completed the results will be displayed in the console window. Scroll down to the very bottom to see the results. The final line should look something like this.
