Ubuntu c++ 删除文件夹或者文件

废话不多说,以下代码中在Remove方法中传入文件路径即可.

//Recursively delete all the file in the directory.
int rm_dir(std::string dir_full_path) {
    DIR* dirp = opendir(dir_full_path.c_str());
    if(!dirp)
    {
        return -1;
    }
    struct dirent *dir;
    struct stat st;
    while((dir = readdir(dirp)) != NULL)
    {
        if(strcmp(dir->d_name,".") == 0
           || strcmp(dir->d_name,"..") == 0)
        {
            continue;
        }
        std::string sub_path = dir_full_path + '/' + dir->d_name;
        if(lstat(sub_path.c_str(),&st) == -1)
        {
            //Log("rm_dir:lstat ",sub_path," error");
            continue;
        }
        if(S_ISDIR(st.st_mode))
        {
            if(rm_dir(sub_path) == -1) // 如果是目录文件，递归删除
            {
                closedir(dirp);
                return -1;
            }
            rmdir(sub_path.c_str());
        }
        else if(S_ISREG(st.st_mode))
        {
            unlink(sub_path.c_str());     // 如果是普通文件，则unlink
        }
        else
        {
            //Log("rm_dir:st_mode ",sub_path," error");
            continue;
        }
    }
    if(rmdir(dir_full_path.c_str()) == -1)//delete dir itself.
    {
        closedir(dirp);
        return -1;
    }
    closedir(dirp);
    return 0;
}
//Remove files or dirs
bool Remove(std::string file_name) {
    std::string file_path = file_name;
    struct stat st;
    if (lstat(file_path.c_str(),&st) == -1) {
        return EXIT_FAILURE;
    }
    if (S_ISREG(st.st_mode)) {
        if (unlink(file_path.c_str()) == -1) {
            return EXIT_FAILURE;
        }
    }
    else if(S_ISDIR(st.st_mode)) {
        if(file_name == "." || file_name == "..") {
            return EXIT_FAILURE;
        }
        if(rm_dir(file_path) == -1)//delete all the files in dir.
        {
            return EXIT_FAILURE;
        }
    }
    return EXIT_SUCCESS;
