说明：  Shell源码:find查找日期为某一天的文件 A=`find ~ -print` | ls -l --full-time $A 2>/dev/null | grep "Jun 27" | grep 1998 下面这个script，存成一个符合规则名字的文件,置上x属性就行了。
(Shell source : find search for a particular day in the paper A = ~ find- print | ls-l-- full-time A $ inversion;/Dev/null | grep "Jun 27" | grep 1998 following the script, save one meet the rules name in the paper, on the x attribute home there.)
