Question

I have a script that renames files to dates entered by the user at the keyboard- It’s very simple, just asks for the month, day, and year. As long as the user enters 2-digit values, it works well… the problem is that sometimes the user does not enter the leading 0, and then the whole thing falls apart. How do I make sure the leading 0 is included?
So far, here is what I have:

    $BatchDay = $(read-host "Enter Day of Month")
    if ($BatchDay -eq ''){$BatchDay = Get-Date -format dd}
    $BatchMonth = $(read-host "Enter Month of Year")
    if ($BatchMonth -eq ''){$BatchMonth = Get-Date -format MM}
    $BatchYear = $(read-host "Enter Year")
    if ($BatchYear -eq ''){$BatchYear = Get-Date -format yy}

Then it concatenates the numbers to build the filename:

    $Filename = "Customer--$BatchMonth-$BatchDay-$BatchYear($BatchNum).txt"

How do I force the variables to be two-digit, even when days and months are only one digit?

Thanks!

Answer 1

You can just create your filename formating your vars :

$a = ("{0:00}-{1:00}" -f 1,2)

gives

01-02

in your case :

$Filename = ("Customer--{0:00}-{1:00}-{2:00}({3:00}).txt" -f $BatchMonth,$BatchDay,$BatchYear,$BatchNum)
