Reinitializes all the git repositories in a given folder. Is recursive by default.

Reinitialize Git Repositories

$gitProjectsFolder = "c:\stash"

"Building up folder list. This may take a minute..."
 
# this will search for git repos up to 4 levels deep
# (not using -Depth so we can support Powershell v4)
$projectFolders = Get-ChildItem $gitProjectsFolder\*,$gitProjectsFolder\*\*,$gitProjectsFolder\*\*\*,$gitProjectsFolder\*\*\*\* -Hidden  -Directory

function DeleteIfExists($file){
	If(Test-Path $file){
		Remove-Item $file -Force
	}
}

foreach ($folder in $projectFolders )
{	
	If( $folder.FullName.EndsWith(".git")){
		DeleteIfExists "$folder.FullName\hooks\prepare-commit-msg"
		DeleteIfExists "$folder.FullName\hooks\prepare-commit-msg.cmd"

		& 'git' "init" "$($folder.Parent.FullName)"
	}
}

Updated to remove old hooks first, so we can spread new hook changes easily to all repos
