".This is confusing so let me explain the difference between ctime, mtime and atime. Files in Linux have 3 types of timestamps: atime (access), mtime (modify) and ctime (change).

ctime means inode/file change time. Unix keeps 3 timestamps for each file: mtime, ctime, and atime.

Timestamps are shown when using the long-format output of ls command, ls -l : ctime is the inode or file change time.

Linux下文件的三个时间戳:atime,mtime,ctime 发表于 2018-02-18 | 分类于 Linux | 浏览 次 在linux系统下每个文件都有三个时间戳,分别为atime,mtime,ctime,具体解释如下:

As this example, # stat arabapak.txt File: `arabapak.txt' Size: 42905 Blocks: 96 IO Block: 32768 regular file Device: 23h/35d Inode: 11653804 Links: 1 Access: (0777/-rwxrwxrwx) Uid: ( 3108/ oraara) Gid: ( 201/ dba) Access: 2013-02-18 08:28:38.428104000 +0100 Modify: 2013-02-01 … (ls 디폴트 시간) 리눅스 ctime (change time, 변경 시간)

Es decir, cambios en los permisos, propietario, etc. ls -l. ls 명령으로 출력되는 값은 기본적으로 mtime 입니다. The below mentioned 3 times is all we have in unix. For a file that is modified today, use either -mtime 0 or -mtime -1 (same for -ctime). Your file is not found because your find predicates -mtime 1 and -ctime 1 search for a file that was modified yesterday (more exactly between 24h ago and 48h ago).

Most people seem to understand atime (access time), it is when the file was last read. Find atime, ctime and mtime with ls The simplest way to confirm the times associated with a file is to use ls command.

También, lo utiliza el comando dump para determinar el último respaldo que se realizó al archivo.

A common misunderstanding is ‘ctime is file creation time’, but this is not true.

A often heard question is "What is the ctime, mtime and atime?

You can find the differences between atime, ctime and mtime by executing command stat FILENAME.

보통 mtime이 변경되면 ctime, atime 값이 모두 변경됩니다.

ctime: 'change time' indica el tiempo de la última modificación que se realizó al archivo en términos de su inodo (inode). 若使用 scp 把文件拷贝到其他机器,mtime, atime, ctime 默认情况下会随之改变,若不想改变,可以在 scp 命令后加上 -p 参数. man scp -p Preserves modification times, access times, and …

今天需要使用find命令来查找一些文件,需要找到15天前创建的文件。究竟该用哪个参数呢,ctime,mtime还是atime? 那就再来复习一下这三个参数具体的意义吧。 不过,在谈论这三个参数之前,你得先了解inode(索引节点)的概念,不然是说不清的。inode是干嘛用的? ctime is the inode change time while mtime is the file modification time. 리눅스 mtime (modification time, 수정 시간) 파일의 내용이 수정될 때 mtime 시간이 변합니다. File created time is not tracked anywhere in unix, so you can’t really determine it.

There does seem to be some confusion between mtime and ctime though.


mtime, atime, and ctime are timestamps associated with the modification, access and change of any file in unix. Example: atime, ctime, mtimeとは? † atime, ctime, mtimeについて以下に記します。 atime access time (アクセスした日時) ctime change time (ステータス変更を行った日時) mtime modify time (データ変更を行った … 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。
