linux命令详解手册(linux切割文件命令)

ainer\">

说明：很多场景需要拷贝或传输文件时，如果我们需要拷贝的文件太大的话，就需要想办法将其分成小个文件进行拷贝，然后载重新合并。今天介绍 split 命令

格式：

<span>split</span> <span>[OPTION]</span> <span>[INPUT [PREFIX]</span>]

一、压缩并切割

使用tar命令进行压缩，使用split进行切割

实例：

# 压缩]# <span>tar</span> <span>-zcvf</span> <span>nginx-v1</span><span>.23</span><span>.1</span><span>.tar</span><span>.gz</span> <span>nginx-v1</span><span>.23</span><span>.1</span># 查看<span>MD5</span>值]# <span>md5sum</span> <span>nginx-v1</span><span>.23</span><span>.1</span><span>.tar</span><span>.gz</span><span>a555bd1453c9e66551b4077d28ab7df3</span>  <span>nginx-v1</span><span>.23</span><span>.1</span><span>.tar</span><span>.gz</span># 切割，指定大小为10<span>M</span>，以数字方式后缀]# <span>split</span> <span>-b</span> 10<span>m</span> <span>-d</span> <span>nginx-v1</span><span>.23</span><span>.1</span><span>.tar</span><span>.gz</span> <span>nginx</span>]# <span>ls</span><span>nginx00</span>  <span>nginx01</span>  <span>nginx02</span>  <span>nginx03</span>  <span>nginx04</span>  <span>nginx05</span>  <span>nginx06</span>  <span>nginx-v1</span><span>.23</span><span>.1</span>  <span>nginx-v1</span><span>.23</span><span>.1</span><span>.tar</span><span>.gz</span>参数说明 <span>-b</span>： 指定大小<span>-d</span> : 使用数字后缀而不是字母

二、解压

<span># 创建一个新目录用来存放分割文件</span>]<span># mkdir src</span>[root@localhost test]<span># mv nginx0* src/</span><span># 解压分割文件</span>[root@localhost test]<span># cd src/</span>[root@localhost src]<span># cat nginx0* >nginx-v1.23.1.tar.gz</span>[root@localhost src]<span># ls</span>nginx00  nginx01  nginx02  nginx03  nginx04  nginx05  nginx06  nginx-v1<span>.23</span><span>.1</span>.tar.gz<span># 核对MD5值</span>[root@localhost src]<span># md5sum nginx-v1.23.1.tar.gz </span>a555bd1453c9e66551b4077d28ab7df3  nginx-v1<span>.23</span><span>.1</span>.tar.gz[root@localhost src]<span># </span>
