How to Open VS Code from Terminal on Mac (Easy Steps)
Visual Studio Code (VS Code) is a powerful and popular source code editor favored by developers for its versatility, extensibility, and user-friendly interface. While you can certainly open VS Code through the typical graphical user interface (GUI) methods (clicking its icon in the Dock, Launchpad, or Applications folder), mastering the ability to launch it from the Terminal unlocks a significant boost in workflow efficiency. This article will provide a detailed, step-by-step guide on how to open VS Code from the Terminal on your Mac, covering various scenarios, troubleshooting tips, and advanced techniques.
Why Open VS Code from the Terminal?
Before diving into the “how,” let’s briefly discuss the “why.” Opening VS Code from the Terminal isn’t just about showing off your command-line prowess; it offers tangible benefits:
- Speed and Efficiency: For developers who spend a significant amount of time in the Terminal (navigating directories, running scripts, using version control), it’s often faster to open VS Code directly from the current working directory without switching contexts.
- Contextual Opening: Opening VS Code from a specific project directory automatically opens that directory within VS Code, saving you the extra step of navigating through the file explorer.
- Advanced Options: The Terminal allows you to use command-line arguments (flags) to control how VS Code opens, such as specifying a particular file, line number, extension, or even comparing files.
- Scripting and Automation: You can incorporate VS Code opening commands into shell scripts to automate your development workflow.
- Remote Development: When working with remote servers or containers (using SSH, Docker, or WSL), the Terminal is often the primary interface, making it essential to launch VS Code from there.
- Troubleshooting: When VS Code is having issues opening normally, sometimes launching it through the terminal with certain flags can help in debugging.
Prerequisites
- Visual Studio Code Installed: Make sure you have VS Code downloaded and installed on your Mac. You can get it from the official website: https://code.visualstudio.com/
- Terminal Access: You’ll need to use the Terminal application, which comes pre-installed on macOS. You can find it in:
/Applications/Utilities/Terminal.app
- Launchpad (search for “Terminal”)
- Spotlight Search (Cmd + Space, then type “Terminal”)
Method 1: Using the code
Command (Recommended)
The most common and recommended method is to use the code
command. This command is a shell command installed by VS Code itself during the installation process (usually, but we’ll cover troubleshooting if it’s not).
-
Open the Terminal: Launch the Terminal application.
-
Install the ‘code’ command (if necessary):
- Open VS Code through your normal method (Dock, Launchpad, etc.).
- Open the Command Palette:
Shift + Cmd + P
(orView > Command Palette
). - Type “Shell Command” in the Command Palette.
- Select “Shell Command: Install ‘code’ command in PATH”. You may be prompted for your administrator password. This command adds the
code
executable to your system’sPATH
environment variable, allowing you to run it from any directory in the Terminal. - Important: You may need to restart your Terminal (close and reopen it) or even your entire system for the changes to take effect. This is because the shell needs to reload its environment variables.
-
Test the
code
command: In the Terminal, type:bash
code -vThis command should display the version number of your VS Code installation. If it does, the
code
command is correctly installed. If you get an error like “command not found,” proceed to the troubleshooting section below. -
Opening VS Code:
-
To open a new VS Code window: Simply type
code
and press Enter:bash
code -
To open the current directory in VS Code: Use
code .
(note the period):bash
code .This is incredibly useful when you’re already working in a project directory in the Terminal. The period (
.
) represents the current working directory. -
To open a specific file: Provide the file path:
bash
code /path/to/your/file.txt
code myfile.py # If myfile.py is in the current directory -
To open a specific folder: Provide the folder path:
bash
code /path/to/your/project
code myproject # If myproject is in the current directory -
To open multiple files or folders:
bash
code file1.txt file2.js folder1
-
Method 2: Using the open
Command (Alternative)
macOS provides a built-in command called open
that can be used to open applications and files with their default applications. While the code
command is generally preferred for VS Code, open
can be useful in specific situations or as a fallback.
-
Open the Terminal.
-
Use the
open
command:-
To open VS Code itself:
bash
open -a "Visual Studio Code"The
-a
flag specifies the application name. Note the use of quotes around “Visual Studio Code” because of the spaces in the name. -
To open a file or folder in VS Code:
bash
open -a "Visual Studio Code" /path/to/your/file.txt
open -a "Visual Studio Code" /path/to/your/project
or, if you are inside the directory already:
bash
open -a "Visual Studio Code" . -
To open a new VS Code window even if one is already open:
bash
open -n -a "Visual Studio Code"
The-n
flag forces a new instance of the application to open.
-
Method 3: Creating an Alias (For Convenience)
If you find yourself frequently opening VS Code from the Terminal, creating an alias can save you some typing. An alias is a shortcut for a longer command.
-
Open your shell configuration file: This file determines the settings and behavior of your Terminal. The most common shells are:
- Bash: The configuration file is usually
~/.bash_profile
or~/.bashrc
. - Zsh (zsh): The configuration file is usually
~/.zshrc
. (Zsh is the default shell on newer macOS versions.)
You can check which shell you’re using by typingecho $SHELL
in the Terminal.
- Bash: The configuration file is usually
-
Edit the configuration file: You can use any text editor to edit this file. For example, to use
nano
(a simple Terminal-based editor):bash
nano ~/.zshrc # Or ~/.bash_profile if you're using Bash -
Add the alias: Add the following line to the file:
bash
alias vscode="code" # Or any alias name you prefer
You could use an alias likec
orvsc
as well. -
Save and close the file: In
nano
, pressCtrl + O
to save, thenEnter
to confirm, andCtrl + X
to exit. -
Reload the configuration file: You need to tell the Terminal to reload the changes you made. You can do this by:
- Closing and reopening the Terminal.
-
Running the
source
command:bash
source ~/.zshrc # Or source ~/.bash_profile
-
Test the alias: Now, you can simply type
vscode
(or your chosen alias) in the Terminal to open VS Code:bash
vscode .
Advanced Usage: Command-Line Arguments (Flags)
The code
command supports a variety of command-line arguments (also called flags) that allow you to control how VS Code opens and customize its behavior. Here are some of the most useful ones:
-
-g
or--goto
: Opens a file at a specific line and column.bash
code -g /path/to/file.txt:10:5 # Opens file.txt at line 10, column 5 -
-r
or--reuse-window
: Forces opening the file or folder in the last active VS Code window, instead of creating a new one.bash
code -r /path/to/file.txt -
-n
or--new-window
: Forces opening a new VS Code window, even if one is already open.bash
code -n /path/to/file.txt -
--diff
or-d
: Opens a diff editor to compare two files.bash
code --diff file1.txt file2.txt -
--wait
or-w
: Waits for the VS Code window to be closed before returning control to the Terminal. This is useful in scripts where you need to ensure that VS Code has finished processing before proceeding.bash
code -w /path/to/file.txt
This will openfile.txt
, and the terminal prompt won’t return until you close that VS Code window or tab. -
--user-data-dir
: Specifies a custom directory for user data (settings, extensions, etc.). This is useful for creating isolated VS Code environments.bash
code --user-data-dir /path/to/custom/data -
--extensions-dir
: Specifies a custom directory for extensions.bash
code --extensions-dir /path/to/custom/extensions -
--list-extensions
: Lists the installed extensions.bash
code --list-extensions -
--install-extension
: Installs an extension.bash
code --install-extension <extension-id>
You can find the extension ID on the VS Code Marketplace webpage for the extension. -
--uninstall-extension
: Uninstalls an extension.bash
code --uninstall-extension <extension-id> -
--disable-extensions
: Disables all installed extensions. Useful for troubleshooting.bash
code --disable-extensions
*--disable-gpu
: Disables GPU acceleration. Can help resolve rendering issues.
bash
code --disable-gpu -
--verbose
: Prints verbose output to the console. Useful for debugging.
bash
code --verbose
To see a full list of available command-line arguments, use:
bash
code --help
Troubleshooting
Here are some common issues and how to fix them:
-
code
command not found:- Ensure you installed the shell command: Follow the steps in Method 1, Step 2 to install the
code
command in yourPATH
. Make sure you restart your Terminal afterward. -
Check your
PATH
: ThePATH
environment variable tells your shell where to look for executable files. You can view your currentPATH
by typing:bash
echo $PATHThe output will be a colon-separated list of directories. The directory containing the
code
executable should be in this list. Typically, this is/usr/local/bin
. If it’s not, you may need to manually add it to yourPATH
. Edit your shell configuration file (~/.zshrc
or~/.bash_profile
) and add a line like this (adjusting the path if necessary):bash
export PATH="/usr/local/bin:$PATH"Then, reload the configuration file (
source ~/.zshrc
orsource ~/.bash_profile
) or restart your Terminal.
* Check for typos: Make sure you’re typingcode
correctly (lowercase, no spaces).
* Reinstall VS Code: If all else fails, try completely uninstalling and reinstalling VS Code. This can sometimes resolve issues with the installation process.
* Symbolic Link Issues: In rare cases, the symbolic link might be broken. You can try creating it manually (be very careful with these commands):bash
sudo ln -s "/Applications/Visual Studio Code.app/Contents/Resources/app/bin/code" /usr/local/bin/code
This command creates a symbolic link (shortcut) from the actualcode
executable within the VS Code application bundle to/usr/local/bin
, which is a standard location for executables. You’ll need to enter your administrator password.
- Ensure you installed the shell command: Follow the steps in Method 1, Step 2 to install the
-
VS Code opens, but the file/folder doesn’t:
- Check the file/folder path: Make sure the path you’re providing to the
code
command is correct. Usepwd
in the Terminal to verify your current directory, and usels
to list files and folders. Remember that paths are case-sensitive. - Relative vs. Absolute Paths:
- Relative paths are relative to your current working directory. For example, if you’re in
/Users/yourname/Documents
and you typecode myfile.txt
, it will look formyfile.txt
in theDocuments
folder. - Absolute paths start from the root directory (
/
). For example,/Users/yourname/Documents/myfile.txt
is an absolute path. Use absolute paths if you’re unsure.
- Relative paths are relative to your current working directory. For example, if you’re in
- Permissions: Ensure you have the necessary read permissions for the file or folder you’re trying to open.
- Check the file/folder path: Make sure the path you’re providing to the
-
Alias not working:
- Correct configuration file: Make sure you added the alias to the correct configuration file for your shell (
~/.zshrc
for Zsh,~/.bash_profile
or~/.bashrc
for Bash). - Reload the configuration: Remember to reload the configuration file using
source
or by restarting your Terminal after making changes. - Typos: Double-check the alias definition for any typos.
- Shell interference: In rare cases, other shell configurations or plugins might interfere with your alias. Try temporarily disabling other customizations to see if that resolves the issue.
- Correct configuration file: Make sure you added the alias to the correct configuration file for your shell (
-
VS Code is slow to open:
- Extensions: Too many extensions, or a poorly performing extension, can slow down VS Code’s startup time. Try disabling extensions one by one to identify the culprit. Use the
--disable-extensions
flag to quickly disable all extensions for testing. - Large Project: Opening a very large project with many files can take longer.
- System Resources: If your Mac is low on memory or processing power, VS Code might open slowly. Close unnecessary applications and processes.
- Hardware Acceleration: Sometimes, disabling hardware acceleration (
--disable-gpu
) can improve performance, especially on older Macs or with certain graphics drivers.
- Extensions: Too many extensions, or a poorly performing extension, can slow down VS Code’s startup time. Try disabling extensions one by one to identify the culprit. Use the
-
“Visual Studio Code.app” is damaged and can’t be opened. You should move it to the Trash.”
- This is a macOS Gatekeeper issue, not directly related to opening VS Code from the terminal. It often happens after downloading VS Code from the official website.
- Solution 1 (Simple): Right-click (or Control-click) on the VS Code application icon in your Applications folder and choose “Open”. You’ll get a similar warning, but this time you’ll have an option to “Open” it anyway. This only needs to be done once.
-
Solution 2 (Terminal): You can use the
xattr
command to remove the quarantine attribute:bash
sudo xattr -rd com.apple.quarantine "/Applications/Visual Studio Code.app"
You’ll need to enter your administrator password. This command removes the extended attribute that’s causing the warning.
Best Practices and Tips
- Learn basic Terminal navigation: Familiarize yourself with essential Terminal commands like
cd
(change directory),ls
(list files),pwd
(print working directory),mkdir
(make directory), andrm
(remove). This will greatly enhance your ability to use the Terminal effectively. - Use tab completion: The Terminal has a powerful feature called tab completion. If you start typing a command, file name, or folder name and press the
Tab
key, the Terminal will try to complete it for you. This saves typing and helps prevent errors. PressTab
twice to see all possible completions. - Explore VS Code’s integrated terminal: VS Code has a built-in terminal that you can access within the editor itself (View > Terminal or
Ctrl + ``
). This allows you to run Terminal commands without leaving VS Code. - Customize your shell: You can customize the appearance and behavior of your Terminal using themes, plugins, and shell configuration files. Popular choices include iTerm2 (a more feature-rich Terminal replacement) and Oh My Zsh (a framework for managing Zsh configuration).
- Use a consistent workflow: Develop a consistent workflow that incorporates the Terminal and VS Code seamlessly. This will improve your efficiency and make you a more productive developer.
