$find = 'jquery-1.5.1'
$replace = 'jquery-1.6.1'
$match = ' *.cshtml' , ' *.vbhtml'

Remove "-whatif" to affect changes

gci -r -i $match | % {
(gc $_ ) | % { $_ -replace $find, $replace } | sc $_ -whatif

dir -r -i $match | sls $find -list | select -exp Path | %{
echo 'more stuff here, maybe tf edit ...';
(gc $) | # in parens so file won't be in use during Set-Content
%{ $
-replace $find,$replace } |
sc $_ -WhatIf:$preview # to keep variable in control, if that is being passed as param

If you need the Select-String you can place it inline (in case you need to check-out the file from archaic SCM, say TFS). Personally I dislike using GCI, I really prefer DIR or LS. I'm really surprised SLS doesn't have a built-in recurse param (grep), until then I'll keep hiding it behind 'DIR -R'.
