推荐答案

从C程序运行shell脚本通常使用

Running a shell script from a C program is usually done using

#include <stdlib.h>
int system (char *s);

其中s是指向脚本路径名的指针，例如

where s is a pointer to the pathname of the script, e.g.

int rc = system ("/home/username/bin/somescript.sh");

如果需要脚本的标准输出，请查看popen手册页.

If you need the stdout of the script, look at the popen man page.
