为什么通过system（）或execvp（）从子进程调用cd shell命令不会工作？
问题描述：
我明白我应该使用chdir（），但我只需要一个解释，为什么通过系统或execvp（）从子进程调用cd shell命令不会工作？感谢!!
I understand that i am supposed to use chdir() but I just need an explanation as to why calling cd shell command through system or execvp() from a child process would not work? Thanks!!
答
因为 chdir 只修改当前环境处理。它不能触及父级环境。
Because chdir only modifies the environment of the current process. It can't touch the environment of the parent.
