tar 删除单个文件

不用解包,删除tar包中单个文件
tar –delete -f xxx.tar file
其中file如果在某个目录下,写全路径。例子如下:

[root@localhost named]# ls -l
total 1652412
drwxr-xr-x  5 named named      4096 Apr 30  2009 chroot
-rw-r--r--  1 root  root  911411200 Sep  2 21:57 name-20100902.tar
-rw-r--r--  1 root  root  778987520 Nov  4  2009 name.tar
[root@localhost named]# tar -tlv name-20100902.tar 

[root@localhost named]# tar -tlvf name-20100902.tar
