解压问题

紫衣伯爵

我在解压的时候遇到这个问题：
[root@localhost cdrom]# tar fcitx-3.2-050827.tar.bz2
tar: Old option `f' requires an argument.
Try `tar --help' for more information.
请问大家这是怎么回事
小弟刚学Linux 还请大家不惜赐教!~~~~~~~

应该用 tar -jxf fcitx-3.2-050827.tar.bz2

谢谢这位兄弟，我试了试成功了，不过不知道这个参数是什么意思，再请您帮我解释一下可吗？谢谢了

To learn about the flags, you should read the man page, i.e. "man tar" or use "tar --help" to show the descriptions.

j - to use bzip2 as compression/decompression filter
x - to extract
f - to specify the filename

So, jxf means to extract file from the specified name through bzip2 alogrithm.

Hope you clear.
