gzip压缩工具

语法：gzip [-dn] filename（n为1-9的数字）

“-d”：解压缩时使用
“-n” （n为1-9的数字）：压缩等级，第1级为最快压缩，但压缩量最小；第9级的压缩速度最慢，但压缩量最大。默认级别为6，“--fast”和“--best”分别等价于“-1”和“-9”。

tar打包工具

tar本身为一个打包工具，可以把目录打包成一个文件，它的好处是它把所有文件整合成一个大文件整体，方便拷贝或者移动。

语法：tar [-zjxcvfpP] filename

“-z”：同时用gzip压缩
“-j”：同时用bzip2压缩
“-x”：解包或者解压缩
“-t”：查看tar包里面的文件
“-c”：建立一个tar包或者压缩文件包
“-v”：可视化
“-f”：后面跟文件名，压缩时跟“-f filename”，意思是压缩后的文件名为filename，解压时跟“-f 文件名”，意思是解压filename。需要注意，如果是多个参数组合的情况下带有“-f”，请把“-f”写到最后面。
“-p”：使用原文件的属性，压缩前什么属性压缩后还什么属性。
“-P”：可以使用绝对路径。
--exclude filename：在打包或者压缩时，不要将filename文件包括在内。
