#?1.?讓使用者輸入檔名，並且判斷使用者是否真的有輸入字串？
echo?-e?"The?program?will?show?you?that?filename?is?exist?which?input?by?you.\n\n"
read?-p?"Input?a?filename?:?"?filename
test?-z?$filename?&&?echo?"You?MUST?input?a?filename."?&&?exit?0
#?2.?判斷檔案是否存在？
test?!?-e?$filename?&&?echo?"The?filename?$filename?DO?NOT?exist"?&&?exit?0

#?3.?開始判斷檔案類型與屬性
test?-f?$filename?&&?filetype="regulare?file"
test?-d?$filename?&&?filetype="directory"
test?-r?$filename?&&?perm="readable"
test?-w?$filename?&&?perm="$perm?writable"
test?-x?$filename?&&?perm="$perm?executable"
#?4.?開始輸出資訊！
