Linux用C++ rz 命令怎么将文件重命名呢？

下午好🌅🌅🌅
本答案参考ChatGPT-3.5

在Linux使用C++ rz命令接收文件后，可以通过以下步骤获取文件名并重命名：

1. 使用C++的popen函数执行rz -b命令，并通过标准输出流读取rz命令的输出结果，以获取接收到的文件名。

   #include 
   #include 
   #define MAX_BUFFER_SIZE 1024
   
   std::string getReceivedFileName()
   {
       FILE *pipe = popen("rz -b", "r");
       if (!pipe)
       {
           std::cerr << "Error executing rz command!" << std::endl;
           return "";
       }
   
       char buffer[MAX_BUFFER_SIZE];
       std::string receivedFileName = "";
   
       while (!feof(pipe))
       {
           if (fgets(buffer, MAX_BUFFER_SIZE, pipe) != NULL)
           {
               receivedFileName += buffer;
           }
       }
   
       pclose(pipe);
   
       // Remove newline character from the end of the file name
       receivedFileName.erase(receivedFileName.length() - 1);
   
       return receivedFileName;
   }
   

2. 调用上述函数获取接收到的文件名，并使用C++的rename函数将文件重命名为所需的新名字。

   int main()
   {
       std::string receivedFileName = getReceivedFileName();
       if (receivedFileName.empty())
       {
           std::cerr << "No file received!" << std::endl;
           return 1;
       }
   
       std::string newFileName = "new_name.txt"; // 你要给文件设置的新名字
   
       if (rename(receivedFileName.c_str(), newFileName.c_str()) == 0)
       {
           std::cout << "File renamed successfully!" << std::endl;
       }
       else
       {
           std::cerr << "Error renaming file!" << std::endl;
       }
   
       return 0;
   }
   

   解决方案摘要：

   1. 使用popen函数执行rz -b命令，并通过标准输出流读取rz命令的输出结果，以获取接收到的文件名。
   2. 使用rename函数将文件重命名为所需的新名字。

   修改后的代码如下：

   #include 
   #include 
   #define MAX_BUFFER_SIZE 1024
   
   std::string getReceivedFileName()
   {
       FILE *pipe = popen("rz -b", "r");
       if (!pipe)
       {
           std::cerr << "Error executing rz command!" << std::endl;
           return "";
       }
   
       char buffer[MAX_BUFFER_SIZE];
       std::string receivedFileName = "";
   
       while (!feof(pipe))
       {
           if (fgets(buffer, MAX_BUFFER_SIZE, pipe) != NULL)
           {
               receivedFileName += buffer;
           }
       }
   
       pclose(pipe);
   
       // Remove newline character from the end of the file name
       receivedFileName.erase(receivedFileName.length() - 1);
   
       return receivedFileName;
   }
   
   int main()
   {
       std::string receivedFileName = getReceivedFileName();
       if (receivedFileName.empty())
       {
           std::cerr << "No file received!" << std::endl;
           return 1;
       }
   
       std::string newFileName = "new_name.txt"; // 你要给文件设置的新名字
   
       if (rename(receivedFileName.c_str(), newFileName.c_str()) == 0)
       {
           std::cout << "File renamed successfully!" << std::endl;
       }
       else
       {
           std::cerr << "Error renaming file!" << std::endl;
       }
   
       return 0;
   }
