tar 文件：
tar cvf xxx.tar dira/ dirb/ filea/ #重新制作xxx.tar，原有内容被覆盖
tar uvf xxx.tar fileb #在原xxx.tar 上增加fileb
tar cvf xxx.tar -C /usr/include ./ # -C causes tar to perform a chdir() to directory. Subsequent file and -C directory arguments are relative to directory. This allows multiple directories not related by a close or common parent to be archived using short relative path names.
解tar包：
tar xvf xxx.tar
显示tar包的内容：
tar tvf xxx.tar
