How do I do 'dir /s /b' in PowerShell?

Question

I have a folder with three files and want the equivalent of dir /s /b in PowerShell. How do I do that?

For example, if the folder name is temp3

Answer 1

If you just want to permanently replace Powershell's dir alias (Get-ChildItem) with a call to cmd dir, for all future powershell windows you're going to open just do the following:

1. notepad $profile (from powershell window)

2. when file opens, insert the following rows and save:

   Remove-Item alias:\dir
   function dir($1, $2, $3, $4) {cmd /r dir $1 $2 $3 $4}
   

Answer 2

Just to enforce, what Joey said:

gci -r -filter *.log | % fullname

This works to find files like dir /s/b *.log does.

---

(dir -r *.log).FullName works as well

---

Execute this once in your powershell shell, to enable a dirsb *.log command:

function global:dirsb {
    param ([Parameter(Mandatory=$true)][string]$fileFilter)
    gci -r -filter $fileFilter | % fullname
}

or add it to your profile: PS> notepad $profile

Answer 3

Adding onto Joey's answer. Starting in PowerShell 3.0, you can use the new Foreach-Object shorthand to get the FullName property.

Get-ChildItem -Recurse | Foreach-Object FullName
gci -r |% FullName

The difference is that you don't need to use curly braces ({}) or the $_ variable if all you need is a property.

Answer 4

You can use

Get-ChildItem -Recurse | Select-Object -ExpandProperty FullName
gci -r | select -exp FullName

or

Get-ChildItem -Recurse | ForEach-Object { $_.FullName }
gci -r | % { $_.FullName }
gci -r | % FullName    # In recent PowerShell versions

(The long version is the first one and the one shortened using aliases and short parameter names is the second, if it's not obvious. In scripts I'd suggest using always the long version since it's much less likely to clash somewhere.)

Re-reading your question, if all you want to accomplish with dir /s /b is to output the full paths of the files in the current directory, then you can drop the -Recurse parameter here.

My advice to you, though: Don't use strings when you can help it. If you want to pass around files, then just take the FileInfo object you get from Get-ChildItem. The cmdlets know what to do with it. Using strings for things where objects work better just gets you into weird problems.

Answer 5

A variation of Bob answer is to use a pipe for realtime output (having a better feedback in large directories):

dir -r | % FullName

Answer 6

This is equivalent:

(dir -r).FullName
