Start-Sleep

模块:
Microsoft.PowerShell.Utility Module

Suspends the activity in a script or session for the specified period of time.

语法

Seconds （默认值） 

Start-Sleep
    [-Seconds] <Double>
    [<CommonParameters>]

Milliseconds 

Start-Sleep
    -Milliseconds <Int32>
    [<CommonParameters>]

FromTimeSpan 

Start-Sleep
    -Duration <TimeSpan>
    [<CommonParameters>]

说明

The Start-Sleep cmdlet suspends the activity in a script or session for the specified period of time. You can use it for many tasks, such as waiting for an operation to complete or pausing before repeating an operation.

示例

Example 1: Pause execution for 1.5 seconds

In this example, the execution of commands pauses for one and one-half seconds.

Start-Sleep -Seconds 1.5

Example 2: Pause execution at the command line

This example shows that execution is paused for 5 seconds when run from the command line.

PS> Get-Date; Start-Sleep -Seconds 5; Get-Date

Friday, May 13, 2022 9:38:15 AM
Friday, May 13, 2022 9:38:20 AM

PowerShell cannot execute the second Get-Date command until the sleep timer expires.

Example 3: Sleep commands using a **TimeSpan**

This example makes all the commands in the session sleep for 30 seconds.

Start-Sleep -Duration (New-TimeSpan -Seconds 30)

参数

-Duration

Uses a TimeSpan object to specify how long the resource sleeps in milliseconds. The value must not be a negative TimeSpan and must not exceed [int]::MaxValue milliseconds.
