While loop powershell
Do UNTIL LOOP in PowerShell?
In addition, PowerShell supports the posttest loops do-while and do-until. In both cases, the instructions in the loop body are executed at least once because the condition is at the end of the loop. From a syntactical point of view, do-while and do-until are identical. The difference is logical in nature.
What is while loop and DO WHILE LOOP?
Do while loop. In most computer programming languages, a do while loop is a control flow statement that executes a block of code at least once, and then repeatedly executes the block, or not, depending on a given boolean condition at the end of the block.
What type of loop is the while loop?
A do-while loop is a kind of loop, which is a kind of control statement. It is a loop with the test at the bottom, rather than the more usual test at the top.
Do WHILE loop syntax?
Contrast with the while loop, which tests the condition before the code within the block is executed, the do-while loop is an exit-condition loop. This means that the code must always be executed first and then the expression or test condition is evaluated. If it is true, the code executes the body of the loop again.

The name comes from the pipe symbol “|” (usually Shift + the key above the left Enter) used to separate commands. Example:
