Powershell/ Print by filename - powershell

Question

My English may not be perfect but I do my best.
I'm trying to write a Powershell script where the filename has a number at the end and it should print exactly that often.
Is this somehow possible ?
With the script it prints it only 1 time.
For whatever reason..
param (
[string]$file = "C:\Scans\temp\*.pdf",
[int]$number_of_copies = 1
)
foreach ($onefile in (Get-ChildItem $file -File)) {
$onefile -match '\d$' | Out-Null
for ($i = 1; $i -le [int]$number_of_copies; $i++) {
cmd /C "lpr -S 10.39.33.204 -P optimidoc ""$($onefile.FullName)"""
}
}

There is no need for parameter $number_of_copies when the number of times it should be printed is taken from the file's BaseName anyway.
I would change your code to:
param (
[string]$path = 'C:\Scans\temp'
)
Get-ChildItem -Path $path -Filter '*.pdf' -File |
# filter only files that end with a number and capture that number in $matches[1]
Where-Object { $_.BaseName -match '(\d+)$' } |
# loop through the files and print
ForEach-Object {
for ($i = 1; $i -le [int]$matches[1]; $i++) {
cmd /C "lpr -S 10.39.33.204 -P optimidoc ""$($_.FullName)"""
}
}
Inside the ForEach-Object, on each iteration, the $_ automatic variable represents the current FileInfo object.
P.S. Your script prints each file only once because you set parameter $number_of_copies to 1 as default value, but the code never changes that to the number found in the file name.
BTW. Nothing wrong with your English
