1.创建文件夹： #include <sys/types.h> #include <sys/stat.h> #include <unistd.h> #include <iostream> using namespace std; int main() { string folder_name = "new_folder"; mkdir(folder_name.c_str(), S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH); //创建文件夹 return 0; } 2.复制文件： #include <stdio.h> #include <stdlib.h> int main() { FILE *fp1, *fp2; //定义两个文件指针 char ch; fp1 = fopen("file1.txt", "r"); //打开要复制的文件 fp2 = fopen("file2.txt", "w"); //打开要复制到的文件 while ((ch = fgetc(fp1)) != EOF) { fputc(ch, fp2); //复制文件 } fclose(fp1); fclose(fp2); return 0; } 3.移动文件： #include <stdio.h> #include <stdlib.h> int main() { char old_path[100] = "old_folder/file1.txt"; char new_path[100] = "new_folder/file1.txt"; int result = rename(old_path, new_path); //移动文件 if (result == 0) { printf("移动成功\n"); } else { printf("移动失败\n"); } return 0; } 4.删除文件夹： #include <unistd.h> #include <stdio.h> int main() { char folder_name[100] = "new_folder"; int result = rmdir(folder_name); //删除文件夹 if (result == 0) { printf("删除成功\n"); } else { printf("删除失败\n"); } return 0; } 5.显示文件夹中的内容： #include <dirent.h> #include <stdio.h> int main() { DIR *dir; struct dirent *ent; char folder_name[100] = "new_folder"; dir = opendir(folder_name); //打开文件夹 while ((ent = readdir(dir)) != NULL) { printf("%s\n", ent->d_name); //遍历文件夹中的文件 } closedir(dir); return 0; } 6.查看文件内容： #include <stdio.h> int main() { FILE *fp; char ch; fp = fopen("file1.txt", "r"); //打开文件 while ((ch = fgetc(fp)) != EOF) { printf("%c", ch); //输出文件内容 } fclose(fp); return 0; } 7.修改文件权限： #include <sys/stat.h> #include <stdio.h> int main() { char file_name[100] = "file1.txt"; chmod(file_name, S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP | S_IROTH); //修改文件权限 return 0; } 8.搜索文件： #include <dirent.h> #include <stdio.h> #include <string.h> int main() { DIR *dir; struct dirent *ent; char folder_name[100] = "new_folder"; char search_name[100] = "file1.txt"; dir = opendir(folder_name); //打开文件夹 while ((ent = readdir(dir)) != NULL) { if (strcmp(ent->d_name, search_name) == 0) //搜索文件 { printf("找到文件：%s\n", ent->d_name); break; } } closedir(dir); return 0; }将上述代码整合成一个完整的程序代码
