如何查看顶部进程的完整列表

如何查看顶部进程的完整列表

当我执行“top”时,我了解到有许多进程正在运行,其中许多进程处于睡眠状态。我需要查看当时所有进程的完整快照。 “顶部”能够显示适合一个屏幕的进程列表。如何获得完整的列表?

除此之外,我有兴趣查看处于“睡眠”状态的所有进程的列表。我不认为我可以在“ps”命令的输出中获取进程状态

答案1

top -b似乎正在做这件事。

答案2

您可以使用 coreutils 获取进程状态ps

$ ps aux

将列出所有这些,甚至更多。以下是如何从手册页中解码它们:

过程状态代码

以下是 s、stat 和 state 输出说明符(标题“STAT”或“S”)将显示的不同值,用于描述进程的状态:

   D    uninterruptible sleep (usually IO)
   R    running or runnable (on run queue)
   S    interruptible sleep (waiting for an event to complete)
   T    stopped, either by a job control signal or because it is being traced.
   W    paging (not valid since the 2.6.xx kernel)
   X    dead (should never be seen)
   Z    defunct ("zombie") process, terminated but not reaped by its parent.

对于 BSD 格式并且使用 stat 关键字时,可能会显示其他字符:

   <    high-priority (not nice to other users)
   N    low-priority (nice to other users)
   L    has pages locked into memory (for real-time and custom IO)
   s    is a session leader
   l    is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
   +    is in the foreground process group.
