4.3 压缩时显示指令执行过程
[deng@localhost test]$ gzip -v passwd
passwd: 61.0% -- replaced with passwd.gz
[deng@localhost test]$ ls
etc passwd1.gz passwd.gz

4.4 将当前目录下每个文件压缩成 .gz 文件
[deng@localhost test]$ ls
a b c d e
[deng@localhost test]$ gzip *
[deng@localhost test]$ ls
a.gz b.gz c.gz d.gz e.gz
[deng@localhost test]$

**注意：**如果是目录，将被忽略。
4.5 解压.gz文件,不保留原文件
[deng@localhost test]$ gzip -d a.gz
[deng@localhost test]$ ls
a b.gz c.gz d.gz e.gz
[deng@localhost test]$

[deng@localhost test]$ gzip -d *.gz
[deng@localhost test]$ ls
a b c d e

4.8 递归的压缩目录
使用 -r 选项，递归压缩 doc 目录以及子目录下的所有文件（目录依然存在）。
[deng@localhost test]$ gzip -rv test/
test//a: 0.0% -- replaced with test//a.gz
test//b: 0.0% -- replaced with test//b.gz
test//c: 0.0% -- replaced with test//c.gz
test//d: 0.0% -- replaced with test//d.gz
test//e: 0.0% -- replaced with test//e.gz
[deng@localhost test]$ tree testtest
