用C ++执行脚本 [英] execute script with C++

问题描述

我想通过c ++程序执行脚本并获取其输出.目前我正在做

I want to execute a script through a c++ program and get its output. Presently I am doing

system("./script.sh > out.txt");

但是我需要一个将输出转换为字符串的命令，例如:

But I need a command that get the output to a string, some thing like:

out = system("./script.sh");
printf(out);

执行脚本后，我无法读取文件out.txt，因为我对此没有权限.我将c ++程序部署在其他没有该权限的框架(boinc)上.

I can't read the file out.txt after execute the script because I don't have permission to that. I deployed my c++ program at other framework (boinc) that doesn't give me this permission.

有人暗示吗? 提前致谢！ 费利佩

Does anybody have a hint? Thanks in advance! Felipe

推荐答案

您可以使用popen()，然后从popen()

FILE  *fp;
fp=popen("./script.sh","r");

并获取您的输出.您可以使用fgets()或fread()从管道读取文件，就像从文件中读取文件一样

and to get your output. you can use fgets() or fread() to read from pipe like you read from a file
