Return value Read-Host in a function

Hi everyone,

Reason:

I receive .tif files from users but usually not in the correct format. Because of that I need to rename about 30 files every day. It requires to be in a bit of a strange format as they are automatically imported into another system. In about six months this will all be automated but until then I don't feel like doing it all manually.

Issue:

I want to use a function as I would have the same code four times in this script. When I use the Do {rev... -eq 2} straight in the code it works. I have no idea how to return a read-host value from a function. After googling and testing a few things I cannot get it to work and I do not receive any error messages.

Does it have something to do with the scope of the function or something like that? Can anyone help me out? Maybe it is something small that I'm missing.

Code:

FunctionRead-Revision

{

Do {$revision=Read-host"Revision"} while ($revision-notmatch"^\d{2}"-and$revision.name.length -eq2)

return $revision

Write-Host $revision

}

#Get all .tif files.

$List

=get-childitem$Directory|where {$_.extension -eq".tif"}

ForEach ($tiffilein$list)

{

#When format is 1234567.tif

If($tiffile.name.length -eq11)

{

If($tiffile.name.substring(7,4) -eq".tif")

{

$number=$tiffile.name.substring(0,7)

Write-Host"Only number"

Set-Focus

Read-Revision

Read-Sheet

Read-Format

 }

}

}

Format Sample:

9999999-03-sht01-A0.tif

9999998-01-sht01-A1.tif

9999998-01-sht02-A3.tif
