What does the future hold for start-ups in 2017? While no one can say for sure, experts have some predictions on what is likely to happen.
The “start synonym” is a command-line tool that allows users to start an application at the root of their file system. It’s similar to the “start” command, but it starts applications from the root instead of just starting them in a directory.
The PowerShell Start-Sleep cmdlet, sometimes known as the sleep alias, is a basic cmdlet that pauses a script. The cmdlet stops just a script or module in the PowerShell session until the appropriate time in seconds or milliseconds has expired whether invoked in the PowerShell console, a script executed by the console, or in the PowerShell ISE.
This cmdlet is basic, but it may be used in a variety of ways to help us scripters create well-written scripts.
Use of the Start-Sleep Cycle
Because the Start-Sleep cmdlet only requires two arguments, it’s quite simple to use. Let’s imagine I need to halt my script while I wait for a different environmental process to complete. That procedure takes around 10 seconds, and I need to make sure my script doesn’t continue to execute until the external event is completed.
I’d just use Start-Sleep -Second 10 to halt the script for 10 seconds. I could also specify the time in milliseconds as Start-Sleep -Milliseconds 10000 if I wanted to really anal about things.
Example of a Situation
A while loop is one of the most typical places to utilize the Start-Sleep cmdlet. A while loop is a PowerShell component that runs code while something else is going on. Waiting for something else to happen is one of the finest applications of a while loop. Instead of estimating how long a process would take and calling this cmdlet directly, you may use this cmdlet.
For instance, you may need to wait for a file to appear in a folder. Perhaps another piece of software dumped the file there. You’ll need to execute some code on the file once it’s in the folder. This is a great example of how to use a while loop with Start-Sleep.
My code in the example below is waiting for the C:File.txt file to appear. If this were in a script, the script would be paused until this event occurred. We don’t require Start-Sleep to perform this, but if you don’t use it, your machine will be crippled. It would be up to PowerShell to determine how quickly it could check for this file on a regular basis!
This file does not need to be checked every.0455ms. Instead, we should reduce the frequency of the check and only do it every five seconds. The Start-Sleep command is a fantastic way to slow down a while loop.
while (-not (Test-Path -Path $filePath)) $filePath = ‘C:File.txt’ ## Start-Sleep -Seconds 5 Start-Sleep -Seconds 5 Start-Sleep -Seconds 5 Start-Sleep -Seconds

The “starting meaning” is a word that has many meanings. It can mean to start something, or it could mean the beginning of something.
