Powershell 'cd' that behaves properly: zero args bring you home, passing '-' brings you to the previous dir

~\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1

del alias:cd -Force # Remove builtin cd alias to Set-Location
function cd {
	$pwd = Get-Location
	if ($args.Count -eq 0) {
		Set-Location ~
	} elseif ($args[0] -eq "-") {
		Set-Location @global:OLDPWD
	} else {
		Set-Location @args
	}
	$global:OLDPWD = $pwd
}

# Bonus: Make autocompletion work like on bash:
Set-PSReadlineKeyHandler -Key Tab -Function Complete
# Or like in zsh:
# Set-PSReadlineKeyHandler -Key Tab -Function MenuComplete
