The DEBUGFS command is a powerful utility in Linux that grants access to the file system of a block device. One of its notable features is its ability to reveal the creation time of a file, which cannot be easily obtained through typical Linux commands. This piece of information is stored in a data structure known as the inode, which houses diverse particulars about the file, including its creation time. To obtain the data using the DEBUGFS command accesses the inode of the file and provides a comprehensive view of the file system. This command facilitates the identification of the ... Read More
