C++ vector change in text.txt file and add text - c++

Question

#include <iostream>
#include <string>
#include <stdio.h>
#include <cstring>
#include <fstream>
#include <vector>
#include <iterator>
using std::cout;
using std::cin;
using std::endl;
using std::string;
std::string FilesOpen(std::string command)
{
const int size_buffer = 2;
char buffer[size_buffer];
memset(buffer, 0, size_buffer * sizeof(char));
std::string result = "";
// Open pipe to file
FILE* pipe = popen(command.c_str(), "r");
if (!pipe)
{
return "popen failed!";
}
// read till end of process:
while (!feof(pipe))
{
// use buffer to read and add to result
if (fgets(buffer, 2, pipe) != NULL)
{
result += buffer;
memset(buffer, 0, size_buffer * sizeof(char));
}
}
pclose(pipe);
return result;
}
int main(int* agrc, char* agrv[])
{
std::vector<std::string> pole;
std::string text;
// get files names and use to ifstream files
FilesOpen("ls /root/workspace/src/server > /root/workspace/filestext.txt");
// get files info size and names
FilesOpen("ls -l /root/workspace/src/server > /root/workspace/filelist.txt");
// get files name and add vector
std::ifstream files;
files.open("/root/workspace/filestext.txt", std::ios_base::in);
if (!files)
{
std::cout << "Error not open files" << std::endl;
}
while (files >> text)
{
pole.push_back(text);
}
files.close();
for (std::vector<std::string>::iterator it = pole.begin(); it != pole.end(); ++it)
{
std::cout << *it << std::endl;
}
// replace text in shell
std::string filereplace = "/root/workspace/testovaci.sh";
std::ofstream r_file(filereplace.c_str());
char patch[] = "patch=";
if (r_file.is_open())
{
for (int i = 0; patch[i] != '\0'; i++)
r_file.put(patch[i]);
r_file.put('D');
}
r_file.close()
}
I need to get the contents of the file name from the filetext.txt file and ignore the folders and list them in the testovaci.sh script, which looks like this:
neco1
neco2
neco3
patch =
neco4
neco5
I need to put in the testovaci.sh file has been added to patch = "file". "file". "file"
and the folders were ignored, leaving only binary files.
Please help me, as I tried everything but nothing works.
