You’ll see the full path of the file displayed on the terminal, as shown below: Open your terminal and run the following command: touch demo.txtĪfter creating the file, run the following command to identify its full path: realpath demo.txt Find File Creation Date/Time Using stat Commandįirst, let's create a new file named demo.txt. Next, let’s explore three different ways we can find out when a file was created in Linux. Essentially, it's the base or 'root' of the tree that forms the directory structure of the entire system.Īs you can see above, the ext4 filesystem is mounted on /, making it the primary filesystem in my Linux distribution (Ubuntu). The primary filesystem is the starting point for the entire filesystem hierarchy, and every other filesystem and directory structure branches off from it. The filesystem mounted on / is the primary filesystem. Running this command will list all mounted filesystems, as shown below:

To check the filesystem of your Linux distribution, run the following command: df -T Check Filesystem of Your Linux Distribution

If you find that you're on a filesystem that doesn't support birth time, then there's no way to retrieve the creation time of the file. So, you’ll have to run the commands and see for yourself.

#Ubuntu find file changed in last month how to

(We'll go over how to check what the primary filesystem in your Linux distribution is in the next section.) But keep in mind, there's no readily available list of Linux filesystems that we know for sure store the file creation time. Each filesystem has a specific structure and rules for controlling how files are named, stored, and organized.Ĭertain filesystems such as ext4 (which is the default on many Linux distributions including Ubuntu) and a few others, do store the creation time of a file. In Linux, a filesystem defines how an operating system manages data storage and retrieval. The addition of the file creation time (birth time) is relatively recent and is not universally supported across all filesystems. However, traditionally, Linux did not track the actual creation time of a file, known as the birth time.

mtime (Modification time): This is the time when the contents of the file were last modified.

Note that this is not the creation time of the file, despite what the name might suggest.

ctime (Change time): This is the time when changes were made to the file’s metadata.

atime (Access time): This is the time when the file was last accessed.

There are three types of timestamps typically associated with a file in Linux: Understanding the Concept of File Creation Time in Linuxīefore diving into the main topic of how to find when a file was created, it's important to have a basic understanding of file timestamps in Linux and why finding the file creation date/time might not always be straightforward. For the purpose of this blog post, I'll be using Ubuntu as my Linux distribution of choice. To follow along with the examples in this blog post, you'll need access to a Linux operating system. In this blog post, we’ll explore three methods of finding out when a file was created in Linux. Whether you're investigating a security issue or debugging a program, the details of when a file was created can provide essential insights. Keeping track of files in Linux is an important part of system administration.
