操作系统：Windows XP
在 cmd shell 中，通过管道输出 fromtasklist /v会做一些奇怪的事情。我正在尝试通过管道连接到 grep，以便过滤输出，结果是断断续续且不一致的。查看问题所在的一种更简单的方法tasklist /v是简单地执行命令tasklist /v | more- 一定有一堆奇怪的（光标向上？？）字符tasklist /v正在喷涌而出。任何人有任何见解？
这是来自的直接输出tasklist /v：

注意一半的输出丢失了，命令提示符出现在列表的中间。tasklist /v | more每次调用都会导致不同的、奇怪的行为。
这是第一次暂停的屏幕截图more：
请注意丢失了多少数据以及光标的奇数位置。这是在上面的 cmd shell 窗口中点击空格后的截图：
这次你看不到光标（我没有在正确的时间点击 prtsc），但它就在该行的正上方--- more --。
