今天在Linux服务器中解压一个zip的压缩包，提示如下错误信息：
[root@appsrv01 ZIP_BCSA_COURSES]# unzip BCSA_MEDIAS_BAK_20161118.zip
error: Zip file too big (greater than 4294959102 bytes)
Archive: BCSA_MEDIAS_BAK_20161118.zip
warning [BCSA_MEDIAS_BAK_20161118.zip]: 31450041244 extra bytes at beginning or within zipfile
(attempting to process anyway)
error [BCSA_MEDIAS_BAK_20161118.zip]: start of central directory not found;
zipfile corrupt.
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)
[root@appsrv01 ZIP_BCSA_COURSES]#
经过百度才知道，原来unzip不能解压超过4GB的zip文件（没想到这么弱。。。），需要把鸟枪换炮（p7zip）了。
yum -y install p7zip
[root@appsrv01 ZIP_BCSA_COURSES]# yum -y install p7zip

安装完毕后使用“7za x BCSA_COURSE.zip”即可解压超过4GB的zip压缩文件。
