Vista - Counting files in a directory

I just noticed that get-childitem (dir, ls) does not return the number
of files shown.

One way is to use (ls splat*).count, but that's not exactly what 'ls'
does. Is there a built in way to do this? Or, should I keep using
the filter I wrote, below?

filter sum($prop="Length") {
begin { $count=0; $total=0 }
process{ $_; $count++; $total+=$_.$prop }
end{ Write-Output ("`nCount: $count, Total: $total, Avg: " + $total/
$count) }
}

Example usage:

ls splat* | sum


Also, is there an easy way to format the numbers as bytes? "233K" or
"12.30M" for example? Even comma insertion would be helpful.

To get count of the files/folders in a Directory:
(get-childitem $directory).Count

For just Files
(get-childitem $directory | ?{!($_.PSIsContainer)}).Count

For just Folders
(get-childitem $directory | ?{$_.PSIsContainer}).Count

Now... for recursive just add -recurse... but beware, could take awhile

As for the conversion (this assumes number is bytes.)
$number/1KB
$number/1MB
$number/1GB

Here some info on it

dir | measure-object -property length -sum -ave

would be a bit more straight forward.

If you have PowerShell Community Extensions installed then you can do this:

13> dir | measure-object -property length -sum -ave |
fl @{l='Sum';e={format-byte $_.Sum}}, @{l='Average';e={format-byte
$_.Average}}


Sum : 597.059 KB
Average : 20.588 KB
