就是这样

你这个是7z，哪里是unzip了？源里的p7zip很久没更新了，对新压缩方法的支持不好，换成真正的unzip一般能解决

卸载了7zip后，使用unzip命令后，输出：
Archive: /home/zcran/下载/pack.zip
[/home/zcran/下载/pack.zip]
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
zipinfo: cannot find zipfile directory in one of /home/zcran/下载/pack.zip or
/home/zcran/下载/pack.zip.zip, and cannot find /home/zcran/下载/pack.zip.ZIP, period.
网上也有要用java的vxf
$ yum -y install java-1.6.0-openjdk-devel
原来网上有很多对于“ End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive.”的解决方案，多谢提醒。
然而并不！能！看！懂！http://askubuntu.com/questions/54904/unzip-error-end-of-central-directory-signature-not-found
......

要么文件损坏，要么它并不是zip格式，只是挂了个名

只是zip的文件名编码问题，论坛有很多方案。
