我希望在shell脚本中获取当前目录的父目录的父目录的基本名称。
例如：
$ pwd
/home/tmp/terminal/env/1239754/control/state
$
我希望得到这个 - 1239754。

我建议使用/* Asking the user if we can access their location */
func Authorization(){
if CLLocationManager.locationServicesEnabled()
{
switch CLLocationManager.authorizationStatus()
{
case .authorizedAlways:
print("Authorized")
case .authorizedWhenInUse:
print("Authorized when in use")
case .denied:
displayAlertWithTitle("Not determined", message: "Location services are not allowed for this app")
case .notDetermined:
print("Not Determined")
if let manager = self.locationManager
{
manager.requestWhenInUseAuthorization()
}
case .restricted:
displayAlertWithTitle("Restricted", message: "Location services are not allowed for this app")
}
}
else
{
print("Location services are not enabled")
}
}
/* Location Detection */
func permission(){
if CLLocationManager.authorizationStatus() == .notDetermined
{
locationManager?.requestAlwaysAuthorization()
}
}
override func viewDidAppear(_ animated: Bool){
super.viewDidAppear(animated)
Authorization()
}
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager = CLLocationManager()
self.locationManager?.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager?.distanceFilter = 200
self.locationManager?.delegate = self
}

根据Cyrus和123的建议，这可能是最简单的解决方案，也适用于unicode角色。只需添加一个/ *
basename ${PWD%/*/*}
输出：
1239754
答案 2 :(得分：0)
你可以试试这个
basename `cd ../..; pwd`
