[Linux-Unix] Process_control DL : 0: 设计并实现Unix的“time”命令。“mytime”命令通过命令行参数接受要运行的程序，创建一个独立的进程来运行该程序，并记录程序运行的时间。在Linux下实现: • 使用fork()/execv()来创建进程运行程序 • 使用wait()等待新创建的进程结束 • 调用gettimeofday()来获取时间 -Design and implementation of the Unix " time" command. " Mytime" command via the command line parameter accepts the program to run, create a separate process to run the program, and recording program to run.
