正規解法應該用
find path -Xtime (+)N -delete

X 應該代換成:
a -> the file last access time (access 也就是說, 讀取也算)
c -> the time of last change of file status information (例如 chmod)
m -> the file last modification time (例如 touch 或是 edit)

(+)N 應該替換成:
N -> N 天內
+N -> N 天以上

例:
    home 目錄中, 一天內存取過的檔案:
    find ~ -atime 1

    刪去目前目錄中, 三天以上沒有修改過的檔案:
    find . -mtime +3 -delete
