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
