unzip trunk.zip
Archive: trunk.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.
unzip: cannot find zipfile directory in one of trunk.zip or
trunk.zip.zip, and cannot find trunk.zip.ZIP, period.
文件大小为 2.2G，可能是 unzip 设置了这个限制吧。在网上查到要用 jar来解压：
jar xvf trunk.zip
如果出现
jar:Command not found
要用yum安装java:
yum -y install java-1.6.0-openjdk-devel
再次运行
jar xvf trunk.zip
就能成功，看来，unzip局限蛮大的呀
