ps aux 状态栏的含义？

Question

在 Mac、64 位、osx 10.8.5 上，我的两条 ps aux 输出行以及标头是；

$ ps 辅助| 头
用户 PID %CPU %MEM VSZ RSS TT STAT 启动时间命令
myuid 16402 0.0 0.0 2432768 600 s005 R+ 9:57PM 0:00.00 grep mongo
myuid 16071 0.0 0.1 3045380 20036 s001 S+ 10:13PM 0:00.51 mongo --nodb

我找不到有关 STAT、状态、列的任何文档。这些项目的含义是什么和/或我如何进一步研究？

没有帮助的事情；维基百科；https://en.wikipedia.org/wiki/Ps_%28Unix%29 此处关于类似问题的另一张海报没有得到回复；https://superuser.com/questions/723080/linuxfedora-what-does-these-stats-column-mean-for-ps-aux-command

Answer 1

从 Linux 系统（man ps）：

           D    uninterruptible sleep (usually IO)
           R    running or runnable (on run queue)
           S    interruptible sleep (waiting for an event to complete)
           T    stopped by job control signal
           t    stopped by debugger during the tracing
           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

此外：

           <    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
