7z指令
7z是7zip压缩工具的常用压缩文件格式。7zip是一个开源的压缩工具，软件本身十分小巧，功能强大，是目前公认的压缩比最大的压缩解压缩软件，近年来开始渐渐流行。

7zip支持众多的压缩格式，支持7z, XZ,BZIP2, GZIP, TAR, ZIP格式的压缩/解压缩。支持CAB, ISO, RAR, RPM, XAR, Z等众多格式的解压缩。

程序退出代码0表示正常，没有错误。

命令格式
$ 7z –help

Usage: 7z […] […]

[<@listfiles…>]

常用的command如下：

a 添加文件到压缩文件

d 从压缩文件中删除文件

e 从压缩文件中解压缩文件，不包含目录结构

l 列出压缩包中的内容

t 测试压缩文件

u更新文件到压缩文件

x从压缩文件中解压缩，包含目录结构

使用示例
$ rm * -rf

$ mkdir -p study/d1/d11 study/d2

$ touch study/d1/d11/f1.c study/d2/f2.php

$ 7z a study.7z study/ ~ 将study整个目录添加到压缩包study.7z中

7zip的压缩格式控制
在上述示例中，演示了7z压缩/解压缩指令的使用。在使用7z进行压缩/解压缩时，压缩格式是根据命令中提供的压缩包的文件后缀名来识别的。例如，7z a study.zip study/ 将目录树study按照zip格式进行压缩，7z a study.7z study/将目录树study按照7z格式进行压缩。反之，解压缩时，压缩格式也是根据压缩包文件名后缀自动识别的。

对于7zip和tar的各种压缩格式（tar.gz tar.bz2 tar.xz）之间的兼容，可以参考如下实现。

$ 7z a study4.tar study ~ step1 先按tar格式进行打包

按照实验结果推断，本条指令与tar cf study4.tar study 具有相同效果
