While loops in PowerShell

While loops in PowerShell

In PowerShell, a while loop is a type of loop that repeats a block of code while a specified condition is $true.

This loop continues to execute the code block as long as the specified condition is $true, and it stops executing the code block when the condition becomes $false.

Example

Here's an example:

$i = 0
while ($i -lt 10) {
Write-Output $i
$i++
}

In this example, the while loop starts by initializing the $i variable to 0.

The code block inside the while loop contains the Write-Output cmdlet, which outputs the value of the $i variable to the console. The $i++ statement is used to increment the value of the $i variable by 1.

The while keyword specifies the condition that must be $true for the code block to continue executing.

In this example, the condition is ($i -lt 10), which means that the code block will continue to execute as long as the value of the $i variable is less than 10.

The while loop will output the numbers 0 through 9 to the console, and it will stop executing the code block when the value of the $i variable becomes 10 or greater.

Conclusion

A while loop is a useful tool in PowerShell for repeating a block of code while a specified condition is $true. It allows you to specify a condition and a code block, and it will execute the code block as long as the condition is $true.
