The `timeout` command in Windows CMD is used to pause the command execution for a specified number of seconds, allowing you to create delays in your scripts or commands.

Here’s the syntax for a 10-second pause:

timeout /t 10

Understanding the Sleep Command in CMD

What is the Sleep Command?

The Sleep Command in Windows CMD is a functional tool that temporarily pauses the execution of commands for a specified duration. It is particularly useful in scripting and automation, allowing users to control when a subsequent command or series of commands should run after a deliberate delay.

The purpose of the Sleep Command varies widely and can include:

Coordinating tasks: When scripts require multiple commands to run in a specific order with necessary delays.
Resource management: Preventing resource overutilization by pacing operations, ensuring that the system does not get overloaded.

Syntax of the Sleep Command

The basic syntax for the Sleep Command is simple:

sleep [duration]

duration is typically specified in milliseconds. For example, a sleep duration of 5000 would pause execution for five seconds.

Example of Basic Syntax

If you wanted to pause your CMD session for 3 seconds, you would write:

sleep 3000

This command instructs the command line interface to halt all further commands for 3000 milliseconds.

How to Use the Sleep Command in Windows CMD

Setting Up Your Command Prompt

To get started with the Sleep Command, you must access the Command Prompt. Follow these steps to open CMD:

Press `Win + R` to open the Run dialog.
Type `cmd` and hit `Enter`.

Ensure that you are running a compatible version of Windows that supports CMD and the Sleep functionality.

Using the Sleep Command Effectively

Basic Examples

One common way to achieve a pause in CMD is using the timeout command, which allows for similar functionality.

timeout /t [seconds]

For instance, to pause for 10 seconds:

timeout /t 10

This command is another way to create a delay, but take note that using timeout will allow the user to interrupt the pause by pressing a key, whereas Sleep will not.

Advanced Usage

One of the most powerful scenarios for using Sleep is in a Batch File. Batch files automate sequences of commands, and incorporating the Sleep command helps manage timing.

Here’s a simple example:

@echo off
echo Starting the process...
sleep 5000
echo Process is running...
sleep 2000
echo Process completed.

In this script, there is a 5-second pause before and a 2-second pause after outputting messages, illustrating how well Sleep can enhance automation flow.

Understanding Duration Parameters

Getting comfortable with duration measurements is crucial. Sleep accepts time in milliseconds, which necessitates some conversions for those accustomed to seconds.

For example:

To pause for 1 minute, you would specify 60000 milliseconds.
For 30 seconds, you would use 30000.

By understanding how to express time in the Sleep command, your ability to control execution timing becomes more precise.

Practical Applications of Sleep Command

Automation Scripts

In automated tasks, timing can significantly affect the process’s success. Incorporating Sleep means you can ensure that each segment of a script waits patiently for resources to become available.

For instance, consider a system maintenance script that needs to stop a service, wait, and then restart it:

net stop "ServiceName"
sleep 10000
net start "ServiceName"

In this example, there is a deliberate pause of 10 seconds after stopping a service to ensure the system has time to release resources before restarting.

Delaying Commands

Delays can often be crucial in scripting, especially when dealing with dependencies. If one command relies on the successful completion of another, a sleep command ensures that the second command does not run prematurely.

For instance:

echo Starting backup...
robocopy C:\Data D:\Backup /E
sleep 5000
echo Backup completed successfully!

Here, using Sleep gives a clear window of time after the robocopy command before notifying the user that the backup process has finished.

Controlling System Resources

By spacing commands out, you can manage system resources more effectively. For example, if you’re deploying updates across multiple systems, adding pauses allows each machine to stabilize before executing the next command.

Consider this scenario:

call update-script.bat
sleep 60000
call another-script.bat

This ensures that the update script has ample time to process before moving on to the next batch of commands, avoiding potential conflicts.

Repair Windows Cmd: Quick Fixes and Tips

Troubleshooting Common Issues

CMD Not Recognizing Sleep Command

At times, you might encounter issues where your CMD doesn’t recognize the Sleep command. This often stems from:

Missing utility: Ensure that the Sleep command is available by using Windows versions that support it rather than compatibility modes.
Path issues: You may have to add the path to your Windows system files in your environment variables.

Performance Issues Related to Sleep

In some scenarios, excessive use of Sleep can result in performance degradation, especially in lengthy scripts. Long sleep durations can lead to scripts running for an extended period unnecessarily.

Tips to optimize:

Use shorter sleep durations when possible.
Analyze whether pauses are essential for command execution logic.

If you need some extra time for a command in your batch file to execute, there are several easy ways to delay a batch file. While the well-known sleep command from older versions of Windows is not available in Windows 10 or 11, you can use the timeout, pause, ping, and choice commands to wait a specific number of seconds or simply pause until the user presses a key. This wikiHow article will teach you 5 simple ways to delay the next command in your batch file on any version of Windows.

Things You Should Know

The timeout command lets you pause for specific number of seconds, until a user presses a key, or indefinitely.
Use the pause command to delay the batch file until a user presses any key, or the choice command to give the user options to choose from.
You can hide on-screen messages that indicate delay to the user by adding >nul to the end of the timeout, ping, and choice commands.

Картинка с сайта: www.wikihow.com
By inserting the timeout command into your batch file, you can prompt the batch file to wait a specified number of seconds (or for a key press) before proceeding.^[1] This command is available on all modern versions of windows, including Windows 10.
- timeout /t <timeoutinseconds> [/nobreak].^[2]
- To pause for 30 seconds and prevent the user from interrupting the pause with a keystroke, you’d enter timeout /t 30 /nobreak.^[3]
  - The user will see Waiting for 30 seconds, press CTRL+C to quit …
- To delay 100 seconds and allow the user to interrupt the delay, you’d use timeout /t 100.
  - The user will see Waiting for 100 seconds, press a key to continue …
- To delay indefinitely until a user enters a keystroke, use timeout /t -1.
  - The user will see Press any key to continue …
- If you don’t want to display a message to the user during the delay, add >nul to the end of your timeout command.

Картинка с сайта: www.wikihow.com
This simple command doesn’t require any flags and you can place it anywhere in your script to prevent further action. When the pause command runs in the batch file, the user will see Press any key to continue . . . on a new line. When the user presses a key, the script continues.^[4]
- You might use pause right before a section of the batch file that you might not want to process, or before providing instructions to the user to insert a disk before continuing.^[5]
- At the pause, you can stop the batch program completely by pressing Ctrl + C and then Y.

Картинка с сайта: www.wikihow.com
You can add a ping anywhere in your batch file, enter any hostname or IP address (including a nonexistent address), and specify the time in milliseconds to delay the next command. You’ll also be able to hide the output of the ping so the user won’t see what’s happening in the background.^[6]
- ping /n 1 /w <timeout in milliseconds> localhost >nul
  - Ping has many more available flags, but for the purpose of delaying a batch file, you’ll only need to use a few. In this case, we’ll ping ourselves by using localhost as our destination.
  - To pause quietly for 10 seconds, you’d use ping /n 1 /w 10000 localhost >nul

Картинка с сайта: www.wikihow.com
You can customize the list of choices, use the default options of Y or N, or choose not to display any choices at all and simply delay your script for a specific period of time.^[7]
- choice [/c [<choice1><choice2><…>]] [/n] [/cs] [/t <seconds> /d <choice>] [/m <text>]
  - /c <choice1><choice2><…>: Specifies the choices you’d like to create, which can include a-z, A-Z, 0-9, and ASCII characters 128-254.
  - /t <seconds>: Use this flag to specify how many seconds to wait before the default choice is selected. You can set this value to any number between 0 (which instantly selects the default choice) and 9999.
  - /d <choice>: Specifies the default choice from the list of choices created with /c.
  - /n (optional): hides the list of choices, but still allows the user to select one.
  - /m <text> (optional): displays a message before the choice list. If you don’t include this flag but don’t hide the choice list, the choices will still be displayed.
  - /cs (optional): This specifies that choices are case-sensitive, which is important if you want to assign different functions to capital and lowercase letters.
- To create a delay with CHOICE without displaying a message or forcing the user to choose something, use rem | choice /c:AB /T:A,30 >nul. This command simply delays the batch file for 30 seconds (similar to using Timeout with no message), provides no choices to the user, and continues after the delay. You can replace 30 with any value up to 9999 (in seconds).

Картинка с сайта: www.wikihow.com
If you’re using Windows XP or earlier, you can use sleep to specify a wait time in seconds. This command will not work in any newer versions of Windows starting with Windows Vista, but is the easiest way to add wait time to batch files running on older systems.
- sleep <seconds>
- The sleep command only requires the number of seconds you want to delay the batch file. For example, to wait 30 seconds before continuing, you’d use sleep 30.

Add New Question

Question

How do I not get a message when I use timeout?

Add the >nul qualifier, like this: timeout /t 120 >nul. This causes a 2 minute delay with no output to the screen.
Question

What if the sleep command doesn’t work?

If the sleep command doesn’t work, use timeout instead.
Question

What if I want to wait less than one second? I can’t just use a dot or a comma.

You can use the ping command. This command, if used with a non-existent IP address, will try to talk to a non-existent computer and give up after a specified number of milliseconds. Just multiply the number of seconds by 1000, and you’re good to go.

You can run a batch file on any Windows computer by double-clicking it, or launch it from the command prompt.
The «PAUSE» command is best used in situations where you’re relying on a user to trigger the next section of the batch file, while the «TIMEOUT» command is suited to situations in which you want to allow the file to run automatically.
The formerly used «SLEEP» command does not work on Windows Vista or later, including Windows 10 and 11.

WAIT

To make a batch file wait for a number of seconds there
are several options available:

PAUSE
SLEEP
TIMEOUT
PING
NETSH (Windows XP/Server 2003 only)
CHOICE
CountDown
SystemTrayMessage
Other scripting languages
Unix ports

Note:

Click a script file name to expand and view its source code; click the file name again, or the expanded source code, to hide the source code again.
To view the source code on its own, right-click the file name and choose Open or Open in separate tab or window.

PAUSE

The most obvious way to pause a batch file is of course the PAUSE command.
This will stop execution of the batch file until someone presses «any key».
Well, almost any key: Ctrl, Shift, NumLock etc. won’t work.
This is fine for interactive use, but sometimes we just want to delay the batch file for a fixed number of seconds, without user interaction.

SLEEP

SLEEP was included in some of the Windows Resource Kits.
It waits for the specified number of seconds and then exits.

SLEEP 10

will delay execution of the next command by 10 seconds.

There are lots of SLEEP clones available, including the ones mentioned in the UNIX Ports paragraph at the end of this page.

TIMEOUT

TIMEOUT was included in some of the Windows Resource Kits, but is a standard command as of Windows 7.
It waits for the specified number of seconds or a keypress, and then exits.
So, unlike SLEEP, TIMEOUT‘s delay can be «bypassed» by pressing a key.

TIMEOUT 10

TIMEOUT /T 10

will delay execution of the next command by 10 seconds, or until a key is pressed, whichever is shorter.

D:\>TIMEOUT /T 10

Waiting for 10 seconds, press a key to continue ...

You may not always want to abort the delay with a simple key press, in which case you can use TIMEOUT‘s optional /NOBREAK switch:

D:\>TIMEOUT /T 10 /NOBREAK

Waiting for 10 seconds, press CTRL+C to quit ...

You can still abort the delay, but this requires Ctrl+C instead of just any key, and will raise an ErrorLevel 1.

PING

For any MS-DOS or Windows version with a TCP/IP client, PING can be used to delay execution for a number of seconds.

PING localhost -n 6 >NUL

will delay execution of the next command for (a little over) 5 seconds seconds (default interval between pings is 1 second, the last ping will add only a minimal number of milliseconds to the delay).
So always specify the number of seconds + 1 for the delay.

The PING time-out technique is demonstrated in the following examples:

PMSleep.bat for Windows NT

```
@ECHO OFF

```

NETSH

NETSH may seem an unlikely choice to generate delays, but it is actually much like using PING:

NETSH Diag Ping Loopback

will ping localhost, which takes about 5 seconds — hence a 5 seconds delay.

NETSH is native in Windows XP Professional and later versions.
Unfortunately however, this trick will only work in Windows XP/Server 2003.

CHOICE

In MS-DOS 6, Windows 9*/ME and NT 4

REM | CHOICE /C:AB /T:A,10 >NUL

will add a 10 seconds delay.
By using REM | before the CHOICE command, the standard input to CHOICE is blocked, so the only «way out» for CHOICE is the time-out specified by the /T parameter.
This idea was borrowed from Laurence Soucy, I added the /C parameter to make it language independent (the simpler REM | CHOICE /T:N,10 >NUL will work in many but not all languages).

The CHOICE delay technique is demonstrated in the following example, Wait.bat:

```
@ECHO OFF
```
```
IF "%1"=="" GOTO Syntax
```
```
ECHO.
```
```
ECHO Waiting %1 seconds
```
```
ECHO.
```
```
REM | CHOICE /C:AB /T:A,%1 > NUL
```

IF ERRORLEVEL 255 ECHO Invalid parameter

```
IF ERRORLEVEL 255 GOTO Syntax
```
```
GOTO End
```
```
 
```
```
:Syntax
```
```
ECHO.
```

ECHO WAIT for a specified number of seconds

```
ECHO.
```
```
ECHO Usage:  WAIT  n
```
```
ECHO.
```

ECHO Where:  n  =  the number of seconds to wait (1 to 99)

```
ECHO.
```
```
 
```
```
:End
```
```
 
```

Note: The line ECHO Invalid parameter ends with an «invisible» BELL character, which is ASCII character 7 (beep) or ^G (Ctrl+G).

In Windows 10 the REM trick no longer works, and the default option is no longer specified with the /T switch, but with a separate /D switch:

CHOICE /C:AB /D:A /T:10 >NUL

This means that, unlike in DOS, in Windows 10 you can skip the delay by pressing one of the choices specified with the /C switch.

The CHOICE delay technique is demonstrated in the following example, Wait.cmd:

```
@ECHO OFF
```
```
IF NOT "%OS%"=="Windows_NT" GOTO Syntax
```
```
IF "%~1"=="" GOTO Syntax
```
```
ECHO.
```
```
ECHO Waiting %~1 seconds
```
```
ECHO.
```
```
CHOICE /C:AB /D:A /T:%1 > NUL
```
```
IF ERRORLEVEL 255 (
```
```
	ECHO Invalid parameter
```
```
	GOTO Syntax
```
```
)

```
ECHO.
```
```
EXIT /B 1
```
```
 
```

CountDown

For longer delay times especially, it would be nice to let the user know what time is left.
That is why I wrote CountDown.exe (in C#): it will count down showing the number of seconds left.
Pressing any key will skip the remainder of the count down, allowing the batch file to continue with the next command.

You may append the counter output to a custom text, like this (@ECHO OFF required):

@ECHO OFF
SET /P \"=Remaining seconds to wait: \" < NUL
CountDown.exe 20

💾 Download CountDown.exe and its C# source code

SystemTrayMessage

SystemTrayMessage.exe is a program I wrote to display a tooltip message in the system tray’s notification area.
By default it starts displaying a tooltip which will be visible for 10 seconds (or any timeout specified), but the program will terminate immediately after starting the tooltip.
The icon will remain in the notification area after the timeout elapsed, until the mouse pointer hovers over it.
By using its optional /W switch, the program will wait for the timeout to elapse and then hide the icon before terminating.

Display a tooltip message for 60 seconds while continuing immediately:

SystemTrayMessage.exe "Your daily backup has been started" /T:"Backup Time" /V:60 /S:186
REM Insert your backup command here

Display a tooltip message and wait for 60 seconds:

SystemTrayMessage.exe "It is time for your daily backup, please save and close all documents" /T:"Backup Time" /V:60 /S:186 /W
REM Insert your backup command here

Or more sophisticated (requires CountDown.exe too):

```
@ECHO OFF
```

SET Message=It is time for your daily backup.\nPlease save and close all documents,\nor press any key to skip the backup.

START /B SystemTrayMessage.exe "%Message%" /T:"Backup Time" /V:20 /S:186 /W

ECHO Press any key to skip the backup . . .

SET /P "=Seconds to start of backup: " < NUL

```
CountDown.exe 20
```
```
IF ERRORLEVEL 2 (
```
```
	ECHO.
```
```
	ECHO Backup has been skipped . . .
```
```
	EXIT /B 1
```
```
)
```

SystemTrayMessage.exe "Your daily backup has been started" /T:"Backup Running" /V:20 /S:186

```
REM Insert your backup command here
```

Non-DOS Scripting

In PowerShell you can use Start-Sleep when you need a time delay.
The delay can be specified either in seconds (default) or in milliseconds.

Start-Sleep -Seconds 10 # wait 10 seconds

```
Start-Sleep 10 # wait 10 seconds
```

Start-Sleep -Seconds 2.7 # wait 3 seconds, rounded to integer

Start-Sleep -MilliSeconds 500 # wait half a second

The following batch code uses PowerShell to generate a delay:

```
@ECHO OFF
```

REM %1 is the number of seconds for the delay, as specified on the command line

powershell.exe -Command "Start-Sleep -Seconds %1"

Or if you want to allow fractions of seconds:

```
@ECHO OFF
```

REM %1 is the number of seconds (fractions allowed) for the delay, as specified on the command line

powershell.exe -Command "Start-Sleep -MilliSeconds ( 1000 * %1 )"

Note that starting PowerShell.exe in a batch file may add an extra second to the specified delay.

Use the SysSleep function whenever you need a time delay in Rexx scripts.
SysSleep is available in OS/2’s (native) RexxUtil module and in Patrick McPhee’s RegUtil module for 32-bits Windows.

Use the Sleep command for time delays in KiXtart scripts.

Use WScript.Sleep, followed by the delay in milliseconds in VBScript and JScript (unfortunately, this method is not available in HTAs).

The following batch code uses a temporary VBScript file to generate an accurate delay:

```
@ECHO OFF
```

REM %1 is the number of seconds for the delay, as specified on the command line

> "%Temp%.\sleep.vbs" ECHO WScript.Sleep %~1 * 1000

```
CSCRIPT //NoLogo "%Temp%.\sleep.vbs"
```
```
DEL "%Temp%.\sleep.vbs"
```

Or if you want to allow the user to skip the delay:

```
@ECHO OFF
```

REM %1 is the number of seconds for the delay, as specified on the command line

>  "%Temp%.\sleep.vbs" ECHO Set wshShell = CreateObject( "WScript.Shell" )

>> "%Temp%.\sleep.vbs" ECHO ret = wshShell.Popup( "Waiting %~1 seconds", %~1, "Please Wait", vbInformation )

>> "%Temp%.\sleep.vbs" ECHO Set wshShell = Nothing

```
CSCRIPT //NoLogo "%Temp%.\sleep.vbs"
```
```
DEL "%Temp%.\sleep.vbs"
```

UNIX Ports

Compiled versions of SLEEP are also available in these Unix ports:

CoreUtils for Windows
A collection of basic file, shell and text manipulation utilities
GNU utilities for Win32
Some ports of common GNU utilities to native Win32.
In this context, native means the executables only depend on the Microsoft C-runtime (msvcrt.dll) and not an emulation layer like that provided by Cygwin tools.

Overview

The SLEEP command in Windows CMD is used to pause the execution of a batch file for a specified number of seconds. This can be particularly useful in scripts where a delay is required between commands, such as waiting for a network service to start or pausing between deployments of different components. SLEEP provides a simple way to introduce a time delay in automated scripts and workflows.

Syntax

The syntax for the SLEEP command is straightforward:

SLEEP time_in_seconds

time_in_seconds: This is the number of seconds that the command processor will pause before continuing with the next command in the script.

Options/Flags

The SLEEP command does not have any options or flags. It simply takes the number of seconds to pause as its sole argument. The absence of options makes it an easy-to-use command without complications.

Examples

Basic Usage: Pause a script for 10 seconds.
```
SLEEP 10
```
This command will halt the script for 10 seconds before proceeding with the subsequent commands.
Using SLEEP in a loop: Example of a countdown from 5 seconds.
```
FOR /L %i IN (5,-1,1) DO (ECHO %i & SLEEP 1)
```
This loop counts down from 5 to 1, pausing for 1 second between each number.

Common Issues

No Fractional Seconds: The SLEEP command does not support fractional seconds. If a fraction is provided, the command rounds down to the nearest whole number. To wait for less than a second, consider using alternative methods like PowerShell’s Start-Sleep -Milliseconds 500.

Script Execution Stops Unexpectedly:
If a script containing the SLEEP command is executed without admin rights where required, or if there are system restrictions, the script may halt unexpectedly. Always ensure appropriate permissions are granted for the scripts to execute correctly.

Integration

SLEEP is often used in conjunction with other CMD commands to manage the timing of operations. Here’s an example of using SLEEP with other commands in a batch script:

@ECHO OFF
ECHO Waiting for system processes to settle...
SLEEP 5
ECHO Launching backup...
START backup_script.bat

In this script, SLEEP is integrated to provide a pause before starting a backup operation.

TIMEOUT: Similar to SLEEP, but includes the ability to interrupt the wait by pressing a key.
PING: Sometimes used as a workaround to create delays, especially when SLEEP is not available in older versions of Windows. Example: PING 127.0.0.1 -n 6 > NUL to wait approximately 5 seconds.

For further details and additional parameters, you can refer to the official Microsoft documentation.

This command works well in various scripting cases, particularly in automation processes, where a delay needs to be enforced between command executions or to simulate staggered starts.
