We can also find files and folders those modified before the specified time. $ find /home -mtime -4 Find Less Then Specified Modification Time Find More Then Specified Modification Time In this example, we will list files and folders those modified at most 4 hours ago. For example to find files and folders those modified before 12 hours we will use -12. If we want to find files those modified after given time we will use - with the time value. $ sudo find /etc -mtime -24 Find Command According To mtime Find Less Then Specified Modification Time This is equivalent to asctime (localtime (seconds)). In this example, we will search files and folders in the directory /etc those modified in the last 24 hour. Python time.ctime () method converts a time in seconds since the epoch to a string in local time. We can provide the time we want to search. We will use -mtime option with the find command. $ ls -l List Modification Time (mtime) Find Command According To mtimeįind command is used to search and find files and directories according to their modification time. We will use regular ls command with the -l option which will list modification time. List Modification Time (mtime)Īs modification time is stored by the file system we can list the modification time of the files and folders. Modification time is used for different purposes like backup, change management etc. This modification time is stored by the file system like ext3, ext4, btrfs, fat, ntfs etc. Modification Time (mtime)įiles and folders are modified in different time during the usage of Linux system. In this tutorial, we will learn how to use mtime attribute with Linux find and related commands. mtime is an attribute used by files, directories and different type of files like text, binary etc. Linux operating system and related technologies and tools provide modification time of the files, folders, executables etc. Prior to modifying a file, an application can save the files mtime, and then reset it after the modification using the utime(2) system call.
