Test to see how much space is saved by using tabs over spaces

Tabs-vs-Spaces-Test

## If there are four spaces, replace them with tabs
Get-ChildItem "C:\temp\Tabs-vs-Spaces\tabs" *.sql -recurse | ForEach {
    (Get-Content $_.FullName | ForEach {$_ -replace "    ", "	"}) | Set-Content $_.FullName
    }

## If there are tabs, replace them with four spaces
Get-ChildItem "C:\temp\Tabs-vs-Spaces\spaces" *.sql -recurse | ForEach{
    (Get-Content $_.FullName | ForEach {$_ -replace "	", "    "}) | Set-Content $_.FullName
    }


## Check the size of the folders, in bytes
$tabsTotalSize = Get-ChildItem "C:\temp\Tabs-vs-Spaces\tabs" *.sql -recurse | Measure-Object -property length -sum
$spacesTotalSize = Get-ChildItem "C:\temp\Tabs-vs-Spaces\spaces" *.sql -recurse | Measure-Object -property length -sum
