Run Batch File Hidden: No Command Prompt Window

Running Batch Files Invisibly in Windows

Batch files provide a convenient method for executing multiple commands sequentially within the Windows operating system. However, users often inquire about the possibility of running these files without a visible console window appearing.

The Challenge of Background Execution

By default, when a batch file is executed, a command prompt window is displayed, showing the commands as they are processed. This can be undesirable in scenarios where a silent, background operation is preferred.

This question originated from SuperUser, a question-and-answer website and a part of the Stack Exchange network.

Methods for Invisible Execution

Several techniques can be employed to run batch files invisibly. One common approach involves utilizing VBScript to launch the batch file.

Here's how it works:

• Create a new text file.
• Paste the following VBScript code into the file:

  Set oShell = CreateObject("WScript.Shell")
  oShell.Run chr(34) & "path\to\your\batchfile.bat" & chr(34), 0, True

• Replace "path\to\your\batchfile.bat" with the actual path to your batch file.
• Save the file with a .vbs extension (e.g., run_silent.vbs).
• Executing the .vbs file will run the batch file without displaying a console window.

The 0 parameter in the oShell.Run method specifies that the window should be hidden. The True parameter ensures the script waits for the batch file to complete before continuing.

Alternative Approaches

Another method involves using the start command within a batch file. This can be achieved by adding the following line to your batch file:

start /min your_batch_file.bat

The /min switch instructs the command prompt to start the batch file minimized, effectively hiding it from immediate view.

It’s important to note that while these methods hide the console window, the process will still be visible in Task Manager.

Addressing the Need for Invisible BAT File Execution

A SuperUser user, Jake, has posed a question regarding the execution of BAT files without the appearance of a command prompt window. He is utilizing the Redcar ruby gem, launched via the command line.

Currently, launching Redcar through its associated BAT file results in a new command prompt window opening, which interrupts his workflow.

The User's Environment and Problem

Jake specifically uses the GITBash shell, provided by MySysGit, as his primary command-line interface. The Redcar gem, when executed, effectively captures the shell until its completion.

The existing Redcar.bat file is intended as a shortcut, but the unwanted command prompt window is a significant inconvenience.

The Core Question

Jake’s primary goal is to execute the BAT file without any visible command prompt appearing. He seeks a method to run the script "silently" or "invisibly."

Potential Solutions

Several approaches can be employed to achieve the desired outcome of running a BAT file without displaying a command prompt window.

Using 'start' Command

The start command in Windows can be utilized to launch applications in a separate window. However, it doesn't inherently suppress the command prompt.

A modified approach using start in conjunction with other techniques might be necessary.

VBScript as an Alternative

A VBScript can be created to execute the BAT file in the background. This method effectively bypasses the need for a visible command prompt.

The VBScript would contain a command to run the BAT file without displaying any windows.

Utilizing PowerShell

PowerShell offers a more robust solution for background process execution. A PowerShell script can be written to launch the BAT file without a visible console window.

This approach provides greater control over the execution environment and error handling.

Creating a Scheduled Task

Configuring a scheduled task to run the BAT file can also achieve the desired result. Scheduled tasks can be set to run without user interaction or a visible window.

This method is particularly useful for automating tasks that need to run periodically or at specific times.

Considerations

When implementing any of these solutions, it's important to consider potential error handling and logging mechanisms.

Without a visible command prompt, debugging can be more challenging, so ensuring proper logging is crucial for identifying and resolving any issues.

Impact on User Experience

While achieving an invisible execution is the goal, it's important to ensure that the user is still aware of the process's status, perhaps through alternative notification methods.

Providing feedback, even without a visible window, can enhance the overall user experience.

Addressing Command Prompt Window Visibility

A SuperUser community member, Afrazier, offers a nuanced response regarding the suppression of Command Prompt windows during batch file execution, presenting both limitations and potential workarounds.

It is not possible to prevent a Command Prompt window from remaining open while a batch file is running, utilizing the built-in Command Prompt functionality. The window will persist until the batch file completes its execution.

However, steps can be taken to expedite the batch file's completion. Modifying the batch file to launch programs using the start command is a viable strategy. This command, by default, initiates a program and immediately returns control to the batch file, allowing it to continue and ultimately exit.

Combining this approach with configuring the shortcut used to execute the batch file to run minimized can further reduce visibility, resulting in only a brief flash of the taskbar.

Considerations for Console-Mode Programs

A caveat exists when dealing with console-mode programs, frequently used by script interpreters. Employing the start command in these instances will spawn a new console window.

In such cases, utilizing the Windows-based version of the interpreter, rather than the console-based version, is recommended. This eliminates the need for the start command.

• For Perl, use wperl.exe instead of perl.exe.
• For Python, utilize pythonw.exe instead of python.exe.
• Older Win32 Ruby distributions include rubyw.exe for similar functionality.

Alternatively, third-party tools exist that can launch the Command Prompt with a hidden window, though specific recommendations are not readily available.

Further insights from another SuperUser thread reveal the possibility of utilizing a Visual Basic Script (VBScript) to not only minimize but completely conceal the CMD prompt. Harry MC details two solutions:

Solution 1:

Create a file named invisible.vbs containing the following line of code:

CreateObject("Wscript.Shell").Run """" & WScript.Arguments(0) & """", 0, False

To execute any program or batch file invisibly, use the following syntax:

wscript.exe "C:\Wherever\invisible.vbs" "C:\Some Other Place\MyBatchFile.bat"

For relaying arguments, use only two double quotes.

CreateObject("Wscript.Shell").Run "" & WScript.Arguments(0) & "", 0, False

Example: Invisible.vbs "Kill.vbs ME.exe"

Solution 2:

Employ a command-line tool, such as Quiet, to silently launch a process.

Implementing any of these methods, based on your proficiency with VBScript and third-party tools, will either minimize the visibility of the Command Prompt window or eliminate it entirely.
