如何搜索并将文件从一个路径移动到另一个 C++？

Question

I'm trying to search all files that follow this pattern " console-* " and move them to another path on my machine if they exist. (For example from: /documents/fs/pstore to /sdk/sys/kernel_dump/ ).

#include <iostream>
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
#include <stdlib.h>

int dirExists(const char *pathname)
{
   struct stat info;

   if( stat( pathname, &info ) != 0 )
      return 0; //  printf( "cannot access %s\n", pathname );
   else if( info.st_mode & S_IFDIR )  // S_ISDIR() doesn't exist on my windows 
      return 1; //  printf( "%s is a directory\n", pathname );
   else
      return 0; //  printf( "%s is no directory\n", pathname );
}

int main()
{
    const char *path = "/documents/fs/pstore";
    if(dirExists(path))
        system("mv /documents/fs/pstore/console-* /sdk/sys/kernel_dump/ ");
    else
        printf( "error" );

    return 0;
}

I've experienced with the code above, but it does not seem to work properly, should I try another approach, maybe with the rename() function? (I'm working on Linux)

Any advice would be greatly appreciated, thank you in advance.

You can call glob() and rename() C functions in Linux if C++17's std::filesystem is not an option for you. glob() gives you the list of files that matches globbing pattern like *, ? and []. However, rename() may fail if the mount position of from and to path are not identical. In this case, you should create your own copy and remove file function.
