how to iterate over files with powershell?

Question

I want to iterate over files in a folder using powershell script;

Answer 1

Get-ChildItem | ForEach-Object { <# do what you need to do #> }

or shorter:

gci | % { <# ... #> }

or if you want an explicit looping construct:

foreach ($file in Get-ChildItem) {
    # ...
}
