".This is confusing so let me explain the difference between ctime, mtime and atime. mtime, atime, and ctime are timestamps associated with the modification, access and change of any file in unix. For a file that is modified today, use either -mtime 0 or -mtime -1 (same for -ctime).

ctime: 'change time' indica el tiempo de la última modificación que se realizó al archivo en términos de su inodo (inode). 보통 mtime이 변경되면 ctime, atime 값이 모두 변경됩니다.

find コマンドの -mtime オプションを指定することで最後にデータが修正された日時で検索することができます。日時の指定方法も色々あるのですが、個人的にわかりづらかったので以下のパターンだとどのような結果になるのか、実際に動かしてみることにしました。 También, lo utiliza el comando dump para determinar el último respaldo que se realizó al archivo.
