I don't think you need a FOR loop to fix this, the OUT-HOST should suffice. Just do

Format-Table <blah blah> | Out-Host ;

And you'll be all set. By the way, when I ran this on my machine, I decided to add -AutoSize to the Format-Table - that is much nicer to deal with.

Cheers!

BTW - if you wanted to allow multiple processes to be chosen you could do this:

$proc[ [int[]](Read-Host "Which ones? ").Split(",")]

See if you like that.

Emitting Objects verses Outputting Text to the Screen

Let's face it, PowerShell does a bunch of magic for you. If we've done our job right, this magic

This is really cool! I've been wanting something like this for a while, but just haven't thought it out yet.

After reviewing all the comments & having more time to think about it, do you have a "better version" written now that you can share with us?

Thanks!

Jeffrey, thanks for your comments and your kind words over on the Powershell team blog.

Matt. The function would now go

Function choose-process

{$global:Counter=-1

$proc=Get-Process

Format-Table -autosize -inputobject $Proc @{ Label = "ID"; Expression={($global:counter++) }} , processName | out-host

$proc[ [int[]](Read-Host "Which ones? ").Split(",")] }

note: I've revised this comment to included Jeffery's multi-select - since I've just written something which actually uses it :-)

I have a set of such functions that basically do the equivalent of SHIFT/CTRL selecting from a list with a mouse. The trick works with just about any Powershell output really. Here's one for selecting directory items:

-------------

## Pick-ChildItem.ps1 ##

param ($path, [array]$index, [switch]$force)

if ($force) {$switch = "-force"}

$global:items = (invoke-expression "get-childitem '$path\*' $switch" |

sort-object @{expression={$_.PSIsContainer}; Descending=$true},

@{expression={$_.Name}; Ascending=$true})

if ($index -ne $null) {

$index | %{$_} | %{$items[$_ - 1]}

}

else {$items | %{$i=1}{$_; $i++} |

format-table @{label="ID"; expression={$i}}, Name,

@{label="Path"; expression={

if ($_.PSISContainer) {"<Dir> $_"}

else {$_.directoryname}}} -auto

}

-------------

usage:

new-alias -name pci -value c:\Scripts\Pick-ChildItem.ps1

pci . <- returns all items in current directory

pci . 4 <- returns fourth item in list

pci . (1..6),(47..50) <- returns all items in ID ranges
