如何知道是否是可执行或二进制是处理一些请求或忙闲(不运行状态)

你可以检查的过程国家代码的过程中使用 ps. 这可以给你一个更详细地了解目前的状态给予过程。

根据 man ps:

PROCESS STATE CODES
   Here are the different values that the s, stat and state output specifiers (header "STAT" or "S") will display to describe the state
   of a process:

           D    uninterruptible sleep (usually IO)
           I    Idle kernel thread
           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

然后你可以做些什么，如： ps --no-headers -o pid,state -p PID 这将输出的一个字母代表的过程的国家从上述的，对于给定的过程PID。

你也可以做 ps --no-headers -o pid,state -p $(pgrep app_name). 这将输出的当前状态的每一个过程，由一个给予应用程序。
