主题Linux文件压缩、解压缩及归档工具
压缩工具很重要的，因为要经常到互联网下载包
一compress/uncompress
compress [-dfvcVr] [-b maxbits] [file ...]
-d: 解压缩，相当于uncompress
-c: 结果输出至标准输出,不删除原文件
-v: 显示详情
uncompress 解压缩
zcat file.Z >file
压缩涉及到压缩算法
比如abcd出现了1000次，那么就可以使用a代替abcd
不同的压缩方法压缩比不一样
对文件进行压缩

-c: 结果输出至标准输出,也就是打印到屏幕上，不删除原文件
我们可以把输出重定向到一个文件里面，这样还保留原文件

二gzip/gunzip
gzip [OPTION]... FILE ...
-d: 解压缩，相当于gunzip
-c: 将压缩或解压缩的结果输出至标准输出
-#：1-9，指定压缩比，值越大压缩比越大
zcat：不显式解压缩的前提下查看文本文件内容
默认是使用压缩比6
-# --fast --best
Regulate the speed of compression using the specified digit #, where -1 or --fast indi‐
cates the fastest compression method (less compression) and -9 or --best indicates the
slowest compression method (best compression). The default compression level is -6
(that is, biased towards high compression at expense of speed).

使用gzip进行解压、
和compress类似，有多种方法
[root@centos72 ~]# gzip -d /app/m.gz
[root@centos72 ~]# ls /app -l
total 1828
-rw------- 1 root root 831851 May 2 17:31 m
-rw-r--r-- 1 root root 831851 May 2 17:58 mm

[root@centos72 ~]# ls /app -lh
total 1.8M
-rw------- 1 root root 813K May 2 17:31 m
-rw-r--r-- 1 root root 813K May 2 17:58 mm
-rw-r--r-- 1 root root 194K May 2 17:55 m.z
解压法2：
[root@centos72 ~]# gzip /app/m
[root@centos72 ~]# ls /app -l
total 1120
-rw------- 1 root root 107731 May 2 17:31 m.gz
-rw-r--r-- 1 root root 831851 May 2 17:58 mm
-rw-r--r-- 1 root root 197701 May 2 17:55 m.z
[root@centos72 ~]# gunzip /app/m.gz
[root@centos72 ~]# ls /app -l
total 1828
-rw------- 1 root root 831851 May 2 17:31 m
-rw-r--r-- 1 root root 831851 May 2 17:58 mm
-rw-r--r-- 1 root root 197701 May 2 17:55 m.z
使用最高压缩比
压缩比越高解压缩就会更慢
压缩要靠CPU大量的做运算，会消耗CPU，不压缩就会占用磁盘空间，所以CPU性能和磁盘空间互换的
raid是利用磁盘空间来换取高性能
CPU很少出故障，但是内存和硬盘就经常出问题
[root@centos72 ~]# gzip -9 /app/m
[root@centos72 ~]# ls /app -l
total 1116
-rw------- 1 root root 106019 May 2 17:31 m.gz
-rw-r--r-- 1 root root 831851 May 2 17:58 mm
-rw-r--r-- 1 root root 197701 May 2 17:55 m.z
[root@centos72 ~]# ls /app -lh
total 1.1M
-rw------- 1 root root 104K May 2 17:31 m.gz
-rw-r--r-- 1 root root 813K May 2 17:58 mm
-rw-r--r-- 1 root root 194K May 2 17:55 m.z
法3：
[root@centos72 ~]# zcat /app/m.gz > /app/mmm
[root@centos72 ~]# ls /app -l
total 1932
-rw------- 1 root root 106019 May 2 17:31 m.gz
