Run a command block based on the results of a conditional test.
Syntax
[:Loop_label] Do
{
command_block
} while (condition)
Key
condition If this evaluates to TRUE the loop {command_block} runs.
when the loop has run once the condition is evaluated again
command_block Commands, separated by commas, to run each time the loop repeats.
:Loop_label An optional label than can be used to break or continue.
As long as the condition remains true, PowerShell reruns the {command_block} section.
'until' may be used in place of 'while' (a synonym)
Examples
Count to 10:
PS> Do { $val++ ; Write-Host $val } while($val -ne 10)
You can use carriage returns instead of semi-colons:
PS> Do { $val++
Write-Host $val
} while($val -ne 10)
