I think I'm missing something simple. I need to append text to each line of output from a Get-ChildItem instruction.

As a simplistic example, picture adding a reference number ('12345') to a folder listing on c:

The output I'm after would look something vaguely like:

c:\Program Files 12345
c:\program Files (x86) 12345
c:\temp 12345
c:\Users 12345
c:\Windows 12345

The real application has more to it, but the end result is that a Powershell script runs a bunch of these commands with some metadata appended to each line which then gets pulled into Excel for reporting.

I just can't figure how to add the string to each line...

  • Excel sounds like CSV. If so do it the proper way and use Export-Csv and give it a data structure to export. Otherwise what did you try to make it happen? A simple string concatenation would work as well or just using an output function with the right quotation marks and argument.

  • I said it was probably simple - string concatenation would almost certainly do the trick but I'm missing how to do that for every line of output

  • This might give you a start gci c:\ -Directory -Recurse | select fullname, {'12345'} Jan 10, 2019 at 7:32
  • Or if you prefer strings (you shouldn't) perhaps this gci c:\ -Directory -Recurse | select {"$($_.fullname) 12345"} Jan 10, 2019 at 7:34
  • A loop would also work. 1..10 | %{ ("ABC $_") }. If you plan to generate a CSV you should use a proper way.

To have the numbers trailing directly to the folder names you can:

gci C:\ -Directory | % { $_.FullName + " 12345"}

More complex with a calculated property

(gci c:\ -Directory | select @{n='WithText';e={$_.FullName + " 12345"}}).WithText
