# 基于Linux系统编程手册的时间与文件操作项目
## 项目简介
本项目是基于《LinuxUnix 系统编程手册》的学习笔记，专注于时间处理和文件操作的实现。项目涵盖了多个章节的内容，通过实际代码演示了如何在Linux环境下进行时间获取、格式化、进程时间统计以及文件的读写、复制、定位等操作。
## 项目的主要特性和功能
1. 时间处理
获取当前时间并展示tm结构体的内容。
获取当前时间戳并转换为本地时间。
显示进程的时间信息，包括用户态和内核态的CPU使用时间。
将时间戳转换为本地时间和格林威治标准时间（GMT），并展示两者之间的差异。
2. 文件操作
文件的读写操作，包括使用read()和write()函数。
文件的复制操作，实现从一个文件到另一个文件的内容复制。
文件的定位操作，使用lseek()函数进行文件指针的移动。
