标签：过程 名称 style grep create centos7 atd nbsp 压缩
命令语法: tar zcvf 生成压缩包路径/压缩包.tar.gz 压缩数据01，02，03....
巧记：
压缩名称为tar.gz，可以理解为tar命令，gz取压缩类型gizp的前2个辅音字母
参数说明:
z --- 数据压缩方式 gzip （--gzip, --gunzip, --ungzip filter the archive through gzip）
c --- 创建一个压缩文件（create create a new archive）
v --- 显示压缩过程（verbose verbosely list files processed）
f --- 指定压缩包路径信息
将链接文件进行压缩处理时:
tar zcvhf 生成压缩包路径/压缩包.tar.gz 需要进行压缩链接文件
h --- 指定压缩链接文件所指定源文件
注意压缩的参数建议加上-，因为很多命令的参数都加-
先创建压缩包，再把文件放到里面，解压缩时磁盘和CPU都会比较卡
注意不要压缩软链接，但是不知道文件是否为软链接，那么就可以加上参数h
[root@centos71 ~]# tar --help | grep "\-h"
-h, --dereference follow symlinks; archive and dump the files they
--hard-dereference follow hard links; archive and dump the files they
-?, --help give this help list
因为/只有一个，所以要去掉/
