Next up, we have for loops. For loops are loops that aren’t quite as smart as foreach loops. For loops have no idea how many elements are in a collection. For loops start at a number, increment that number each time, and stop when a condition is true. The for loop has four diff...
To add the number five to each of the elements in the array, I need to walk through the array by using theForeachcommand. To use theforeachcommand, I need to do three things: I call theForeachcommand. I use a pair of parentheses, I use a variable for my place holder (enumerator)...

It's an array if it contains multiple items.PowerShell Copy $array = 1..5 | ForEach-Object { "ATX-SQL-$PSItem" } Normally when we think of using the pipeline, we think of the typical PowerShell one-liners. We can leverage the pipeline with foreach() statements and other loops....
It loops over the files using a for loop, using the index to access each file in the array. It compares each filename to a regular expression pattern to extract the work item number as a string instead of an integer. Then it compares the lengths of the work item numbers to find the ...
ForEach ($VM in $VMs) This is perfectly fine code – it is the traditional way foreach loops are used. But foreach loops in PowerShell are much more than that. I’ve found that wherever I had code like that, I’m now converting it to the following form: ...
A PowerShell array is a component that enables the storage of more than one item in a variable or a field. For instance, to assign multiple values to a variable, use the script$a=1,2,3. PowerShell treats each item in an array as a separate element. To address each item in an arra...
