How to Run Command Using Command Line Arguments in Windows Terminal

To run a command with arguments in Windows Terminal, use the wt executable followed by the desired profile or shell name. You can append commands directly after the profile identifier to execute them immediately upon tab creation. This method leverages Windows Terminal’s built-in command-line interface to spawn new tabs with specific contexts and initial commands.

Understanding the wt Command Structure

Windows Terminal provides a powerful command-line tool named wt. This utility allows you to control the terminal application from any other program, script, or even another command prompt window. The primary goal is often to open a new tab or pane that starts with a specific command already running, rather than just an empty shell waiting for input. The basic structure of the command is straightforward. You invoke wt, specify the target environment (such as cmd, powershell, or wsl), and then provide the command string you wish to execute. It is crucial to understand that wt does not simply pass arguments to the shell; it constructs a new session based on your configuration settings. If you do not specify a profile, it defaults to your default profile defined in the settings.json file. For users coming from Linux backgrounds who are used to chaining commands directly in their shell initialization, this behavior might seem different. You may find our guide on Jumping Beginning Command in Windows Terminal helpful if you are trying to replicate similar startup behaviors. However, for immediate execution via command line arguments, the syntax is distinct.

Executing Commands in New Tabs

To execute a command immediately when a new tab opens, you need to pass the command as an argument to the wt launcher. The most common scenario involves opening a PowerShell or Command Prompt window that runs a specific script or navigates to a directory. Here is the general syntax:

wt [profile] "command here"

For example, if you want to open a new PowerShell tab and immediately run Get-Process, you would type:

wt pwsh "Get-Process"

This command tells Windows Terminal to create a new tab using the PowerShell profile (pwsh) and execute the Get-Process cmdlet. The quotes are essential because they ensure the entire command string is passed correctly to the shell, especially if the command contains spaces or special characters. If you prefer using the traditional Command Prompt, replace pwsh with cmd:

wt cmd "dir /b"

This will open a CMD tab and list files in the current directory without subdirectories. Note that the command executes within the context of the new tab. Once the command finishes, the tab typically remains open unless the command explicitly exits the shell.

Running Visual Studio Code from Terminal

A very common request is to open Visual Studio Code in a new terminal tab. You can achieve this by invoking the code command. To open the current directory in VS Code and launch a new integrated terminal within it, you can use:

wt code .

However, if you specifically want to run a command *inside* a new WT tab that happens to be VS Code's terminal, you should target the VS Code profile if configured, or simply use the standard code launcher which integrates with WT. For pure command execution, sticking to wt with the appropriate shell profile is more reliable.

Handling Arguments and Spaces

When passing complex commands, proper quoting is critical. Windows shells handle quotes differently depending on whether you are using CMD or PowerShell. In PowerShell, double quotes are generally preferred for string interpolation, while single quotes treat the content as literal. If your command requires nested quotes, such as passing a JSON string or a SQL query, you must escape them appropriately. For instance:

wt pwsh 'Write-Output "Hello World"'

In this example, the outer single quotes protect the entire argument from the wt parser, while the inner double quotes are preserved for the PowerShell interpreter. Always test your command in the target shell first to ensure the quoting works as expected before wrapping it in wt.

Troubleshooting Common Issues

If your command does not run as expected, consider the following checks:

• Profile Existence: Ensure the profile name you specified (e.g., pwsh, cmd) exists in your settings.json. If the profile name is incorrect, wt will fail or default to the main profile.
• Command Syntax: Verify that the command itself is valid in the target shell. A command that works in CMD may fail in PowerShell due to different syntax rules.
• Permissions: Some commands require administrative privileges. If you need to run an elevated command, you may need to configure your terminal profiles to always run as administrator, or launch wt from an already elevated prompt.

Advanced Configuration

You can also define custom actions in settings.json that include pre-launch commands. While this article focuses on command-line arguments, knowing that these configurations exist helps in understanding how wt manages sessions. When using command-line arguments, you override these defaults temporarily. It is important to note that wt does not support arbitrary flag chaining like some older tools. Stick to the documented syntax: wt [profile] [command]. Adding unsupported flags may result in errors or unexpected behavior.

Frequently Asked Questions

Can I open multiple tabs with different commands at once?

Yes, you can chain multiple tab specifications. Use the --new-tab flag followed by the profile and command for each subsequent tab. For example, wt pwsh "ls" --new-tab cmd "dir" will open two separate tabs with different shells and commands.

Why does my command exit immediately after running?

This often happens if the command completes its task and the shell is configured to close on exit. Ensure your command leaves the shell interactive, or add a pause command like pause in CMD or Read-Host in PowerShell to keep the window open.

How do I pass environment variables to the new tab?

Environment variables are inherited from the parent process. If you set a variable in your current session, it is available to the new tab. You can verify this by echoing the variable inside the new command, e.g., wt pwsh "$env:PATH".

Is there a way to wait for the command to finish before closing?

Windows Terminal does not have a universal --wait flag for all scenarios. Instead, design your command to block until completion. For scripts, ensure they do not exit prematurely. If you need to wait for user input, use shell-specific read commands.

What is the difference between using wt and just launching the app?

Launching the app opens the default view. Using wt allows precise control over which profile opens, what command runs initially, and whether it opens in a new tab or pane. It is essential for automation and integrating terminal workflows into other applications.
