1.获取系统命令执行结果

#include <stdio.h>

#define TRUE 1
#define FALSE 0

int get_system_cmd_result(const char *command, char *buffer, int bufferLen) {
    FILE *pipe = popen(command, "r");
    if (pipe == NULL) {
        return FALSE;
    }

    while (fgets(buffer, bufferLen, pipe) != NULL) {
        // 循环读取命令执行结果
    }

    int returnValue = pclose(pipe);
    if (returnValue == -1) {
        return FALSE;
    }

    return TRUE;
}

int main(int argc, char const *argv[])
{
    /* code */
    char buffer[1024];
    if (get_system_cmd_result("md5sum main.cpp", buffer, 1024) == TRUE) {
        printf("ls result: %s\n", buffer);
    }
    return 0;
}
