http://linuxtools-rst.readthedocs.io/zh_CN/latest/tool/ps.html
Linux Tools Quick Tutorial. Linux Tools Quick Tutorial. Ps 为我们提供了进程的一次性的查看，它所提供的查看结果并不动态连续的 如果想对进程时间监控，应该用 top linux下的任务管理器. 中断(休眠中, 受阻, 在等待某个条件的形成或接受到信号). 僵死(进程已终止, 但进程描述符存在, 直到父进程调用wait4()系统调用后释放). 停止(进程收到SIGSTOP, SIGTSTP, SIGTTIN, SIGTTOU信号后停止运行运行). D 不可中断 uninterruptible sleep (usually IO). R 运行 runnable (on run queue). T 停止 traced or stopped. Z 僵死 a defunct ( zombie ) process. 8211;lines 行数 每页显示的行数. 8211;width 字符数 每页显示的字符数. F 代表这个程序的旗标 (flag)， 4 代表使用者为 super user. UID 程序被该 UID 所拥有. TIME 使用掉的 CPU 时间。

1. gdb 调试利器 — Linux Tools Quick Tutorial
http://linuxtools-rst.readthedocs.io/zh_CN/latest/tool/gdb.html
Linux Tools Quick Tutorial. Linux Tools Quick Tutorial. G -g hello.cpp -o hello. Gdb program core dump file $gdb program core.11127. Gdb program PID $gdb hello 11127. Run 简记为 r ，其作用是运行程序，当遇到断点后，程序会在断点处停止运行，等待用户输入下一步的命令。 Continue 简写c 继续执行，到下一个断点处 或运行结束. Next 简写 n ，单步跟踪程序，当遇到函数调用时，也不进入此函数体 此命令同 step 的主要区别是，step 遇到用户自定义的函数，将步进到函数中去运行，而 next 则直接调用函数，不会进入到函数体内。 Step 简写s 单步调试如果有函数调用，则进入函数 与命令n不同，n是不进入调用的函数的. Call 函数(参数) 调用程序中可见的函数，并传递 参数 ，如 call gdb test(55). Quit 简记为 q ，退出gdb. Break n 简写b n :在第n行处设置断点.
2. ldd 查看程序依赖库 — Linux Tools Quick Tutorial
