假设当前目录下有多个zip文件 data.zip invoices.zip pictures.zip visit.zip， 直接 unzip *.zip 等价于 unzip data.zip invoices.zip pictures.zip 会报错
Archive: data.zip caution: filename not matched: invoices.zip caution: filename not matched: pictures.zip caution: filename not matched: visit.zip 因为会认为后面三个zip文件是在第一个zip文件里面的,因此需要 unzip '*.zip' 或者 unzip "*.zip" 或者 unzip \*.zip 来屏蔽掉linux的通配符（man可以看到Be sure to quote any character that might otherwise be interpreted or modified by the operating system, particularly under Unix and VMS.） 或者 for z in *.zip; do unzip $z; done
