linux中如何打包、解包：tar文件

1、测试数据

root@PC1:/home/test2# ls
a.txt  b.txt  c.txt
root@PC1:/home/test2# md5sum a.txt b.txt c.txt
3b0332e02daabf31651a5a0d81ba830a  a.txt
3b0332e02daabf31651a5a0d81ba830a  b.txt
5d634700c6211755a05f842011801338  c.txt

2、打包

root@PC1:/home/test2# ls
a.txt  b.txt  c.txt
root@PC1:/home/test2# tar -cvf xxx.tar a.txt b.txt c.txt
a.txt
b.txt
c.txt
root@PC1:/home/test2# ls
a.txt  b.txt  c.txt  xxx.tar

3、解包

root@PC1:/home/test2# ls
xxx.tar
root@PC1:/home/test2# tar -xvf xxx.tar
a.txt
b.txt
c.txt
root@PC1:/home/test2# ls
a.txt  b.txt  c.txt  xxx.tar
root@PC1:/home/test2# md5sum a.txt b.txt c.txt
3b0332e02daabf31651a5a0d81ba830a  a.txt
3b0332e02daabf31651a5a0d81ba830a  b.txt
5d634700c6211755a05f842011801338  c.txt
