tar——压缩数据/解压数据内容
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

因为/只有一个,所以要去掉/
