[英]command prompt in c++
Guys what am I doing wrong here? 伙计们,我在这里做错了什么?
#include <iostream>
#include <string>
using namespace std;
int main()
{
while (true){
std::string cmd;
cin >> cmd;
const char* com = cmd.c_str();
cout << com << endl;
// cout << sizeof(com) << endl;
system(com);
}
return 0;
}
Everytime I run this it works fine but when you type something like cd ../ it separates the words and runs them as two different commands so first cd, then ../ and it gives me a error. 每次我运行它时,它都运行良好,但是当您键入cd ../之类的东西时,它会将单词分开并以两个不同的命令运行它们,所以先输入cd,然后是../,这给我一个错误。 Any idea on what I'm doing wrong? 关于我在做什么错的任何想法吗? I'm new to C++ anyway also this is supposed to bypass "command prompt has been disabled by your admin on windows" 无论如何,我还是C ++的新手,这应该绕过“您的Windows管理员已禁用命令提示符”
the extraction operator (>>) stops reading when reaching the first white-space if your command consists of spaces then use std::getline: 如果您的命令由空格组成,则提取运算符(>>)会在到达第一个空格时停止读取,然后使用std :: getline:
std::string sCommand;
std::cout << "Enter eommand: ";
std::getline(std::cin, sCommand); // eg enter: color 1f
system(sCommand.c_str()); // c_str(): converts from class string to const char*.
there's no way to pass two arguments one after the other to system when the first arguments invokes a program and the second is passed to it but you can make on big command then pass it. 当第一个参数调用程序并将第二个参数传递给程序时,无法将两个参数一个接一个地传递给系统,但是您可以执行大命令然后将其传递。
system("diskpart"); // invoking diskpart
system("list vol"); // here list vol is not passed to diskpart but only to cmd
system("notepad.exe C:/desktop/mylog.txt"); // ok
