Unable to Find Way Permanently Delete ext4 Directory in Ubuntu 24.04
If you have accidentally deleted a folder or subfolders in a second disk machine that uses Ubuntu 24.04 and the ext4 filesystem, and you have searched for the undeleted directory and files without success, then this article is for you.
Introduction
Deleting files and directories is a common operation that is performed in any operating system. However, sometimes, you may accidentally delete a critical folder or subfolder that contains important files. In such cases, you may want to recover the deleted files or directory. This article will guide you on how to permanently delete an ext4 directory in Ubuntu 24.04, in case you have searched for the undeleted directory and files without success.
Understanding the ext4 Filesystem
The ext4 filesystem is a popular filesystem used in Linux distributions, including Ubuntu. It is an improvement of the ext3 filesystem and provides better performance, scalability, and reliability. The ext4 filesystem uses inodes to store metadata about files and directories. When you delete a file or directory, the inode is marked as free, but the data blocks that contain the file or directory contents are not immediately erased.
Permanently Deleting an ext4 Directory
To permanently delete an ext4 directory in Ubuntu 24.04, you can use the rm command with the -rf options. The -r option will remove the directory and its contents recursively, while the -f option will force the removal of the directory and its contents without prompting for confirmation.
$ rm -rf /path/to/directory
It is essential to note that the rm command will not delete the data blocks that contain the file or directory contents immediately. To ensure that the data blocks are erased, you can use the shred command. The shred command will overwrite the data blocks with random data, making it impossible to recover the deleted files or directory.
$ shred -n 1 -z -u /path/to/directory
In the above command, the -n option specifies the number of times that the data blocks will be overwritten (in this case, once), the -z option adds a final pass of zeros to hide the shredding process, and the -u option will delete the directory and its contents.
Accidentally deleting a folder or subfolders in a second disk machine that uses Ubuntu 24.04 and the ext4 filesystem can be frustrating. However, this article has provided a detailed guide on how to permanently delete an ext4 directory in Ubuntu 24.04, in case you have searched for the undeleted directory and files without success.
