c语言+linux系统调用汇聚总目录下(含子目录)的所有文件到一个目录

1、使用方法
将main.c拷贝到总目录下，编译成a.out，运行a.out即可在总目录下的dstPath文件夹下汇聚总目录下(含子目录)的所有文件（. .. main.c a.out dstPath已排除）。
2、汇聚可以修改代码来决定是mv还是cp。
3、文件名有特殊字符的情况，有些字符代码已经转义，如果还有其他的转义即可。

main.c：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <dirent.h>
#include <unistd.h>

void geditFileName(char *name, int n)
{
    char newName[1000];
    char* ptrNewName = newName;
    char* ptrOldName = name;

    if(n < 1 || name == NULL)
    {
        return ;
    }

    memset(newName,'\0',sizeof(newName));
    while((*ptrNewName = *ptrOldName) != '\0')
    {
        if(*ptrNewName == ' ')
        {
            *ptrNewName = '\\';
            ptrNewName++;
            *ptrNewName = ' ';
            n++;
        }
        if(*ptrNewName == '=')
        {
            *ptrNewName = '\\';
            ptrNewName++;
            *ptrNewName = '=';
            n++;
        }
        if(*ptrNewName == '&')
        {
            *ptrNewName = '\\';
            ptrNewName++;
            *ptrNewName = '&';
            n++;
        }
        if(*ptrNewName == '(')
        {
            *ptrNewName = '\\';
            ptrNewName++;
            *ptrNewName = '(';
            n++;
        }
        if(*ptrNewName == ')')
        {
            *ptrNewName = '\\';
            ptrNewName++;
            *ptrNewName = ')';
            n++;
        }
        if(*ptrNewName == '+')
        {
            *ptrNewName = '\\';
            ptrNewName++;
            *ptrNewName = '+';
            n++;
        }
        ptrNewName++;
        ptrOldName++;
    }
    strncpy(name, newName, n);
