批处理文件，用于标识命名窗口是否已打开，然后将其关闭

Question

我一直在使用以下脚本来检查特定命名窗口是否已打开。

我从这个帖子中得到了它： -

How do you test if a window (by title) is already open from the command prompt?

理想情况下，如果发现它已打开，我会展开else部分以关闭窗口。

@For /f "Delims=:" %A in ('tasklist /v /fi "WINDOWTITLE eq test.bat - Notepad"') do @if %A==INFO (echo Prog not running) else SET "BREX=Awesome" &echo %BREX%

不幸的是，当我运行这个脚本时，它会返回我的其他字符串的三个实例？

有没有办法将其减少到返回一个实例？

您可以使用# models class Store(models.Model) name = models.TextField() class Stuff(models.Model) store = models.ForeignKey(Store, related_name='stuffs') first_name = models.TextField() last_name = models.TextField() # serializers class StuffSerializer(serializers.ModelSerializer): class Meta: model = Stuff fields = ('id', 'first_name', 'last_name', ) class StoreSerializer(serializers.ModelSerializer): stuffs = StuffSerializer() def create(self, validated_data): instance = Stoer.objects.create(name=validated_data['name'] for stuff in validated_data['stuffs'] Stuff.objects.create(store=instance, first_name=stuff['first_name'], last_name=stuff['last_name']) return instance def update(self, instance, validated_data): instance.name = validated_data['name'] instance.save() for stuff in validated_data['stuffs'] stuff_instance = Stuff.objects.get(id=stuff['id']) stuff_instance.first_name=stuff['first_name'] stuff_instance.last_name=stuff['last_name'] stuff_instance.save() return instance class Meta: model = Store fields = ('id', 'name', 'stuffs', ) # ModelViewSet class StoreViewSet(viewsets.ModelViewSet): queryset = Store.objects.all() serializer_class = StoreSerializer 代替。当你在每行输出上循环时，你会得到多行输出

findstr

如果你真的想通过cmd提示符中的一行执行此操作，则可以执行此操作。

var valueeee = 'NoneNoneNoneBP #15 Plain Felt 36" | $10.00NoneNoneNoneNoneNoneNone'

var strs = valueeee.replace(/\None/g,'');
var str = valueeee.replace(/\None|\|/g,'');
console.log(str);
console.log(strs);

或者使用一些条件执行。

 cmd /v:on /c "@For /f "Delims=:" %A in ('tasklist /v /nh /fi "WINDOWTITLE eq test.bat - Notepad"') do @if %A==INFO (echo Prog not running) else (SET "BREX=Awesome") &echo !BREX!"
