In the world of computing, it’s not uncommon to accidentally delete or overwrite a file, and then wish you could turn back time. Fortunately, on Ubuntu, there are several ways to recover a previous version of a file. This article will guide you through the process.
To recover a previous version of a file on Ubuntu, you can check for hidden backup files in the same directory as the original file. These backup files have the same name as the original file, but with a "~" appended to the end. If a backup file exists, you can restore it by renaming it to its original name using the mv command in the terminal. However, it is recommended to implement a version control system like Git or Bazaar to easily revert to previous versions of files.
Checking for Backup Files
If you’ve been using a text editor like GEdit and haven’t disabled its backup function, there’s a good chance that there’s a hidden backup file in the same directory as your original file. This file will have the same name as your original file, but with a “~” appended to the end. For instance, if your file was named document.txt, the backup file would be document.txt~.
To check for the existence of such a file, open the terminal and navigate to the directory containing your file. You can use the cd command to change directories. For instance, to navigate to the Documents directory, you would use:
cd ~/DocumentsOnce you’re in the correct directory, list all files, including hidden ones, with the ls -a command:
ls -aThis command will display all files in your current directory, including hidden ones. If a backup file exists, it should show up in this list.
Enabling Hidden Files
If you can’t see the backup file in the terminal, you might need to enable the display of hidden files in your file manager. In Ubuntu’s default file manager, Nautilus, you can do this by pressing Ctrl+H or by going to the View menu and selecting Show Hidden Files.
Restoring the Backup File
Once you’ve located the backup file, you can restore it by renaming it to its original name. In the terminal, you can use the mv command to rename files. For instance, to rename document.txt~ to document.txt, you would use:
mv document.txt~ document.txtThis command will overwrite the existing document.txt file with the contents of document.txt~, effectively restoring the previous version of the file.
Implementing a Version Control System
While the above methods can help in a pinch, they’re not foolproof. If you’ve saved your file multiple times since the version you want to restore, the backup file will have been overwritten, and you won’t be able to recover the previous version.
To avoid such situations in the future, consider implementing a version control system like Git or Bazaar. These tools keep track of all changes made to your files, allowing you to easily revert to a previous version if necessary. You can learn more about how to use these tools in the Git documentation and the Bazaar documentation.
Conclusion
While Ubuntu doesn’t have a built-in file versioning system like some other operating systems, it’s still possible to recover previous versions of files with a little bit of work. However, the best way to protect your files is to implement a robust backup and version control system. This will ensure that you can always recover your files, no matter what happens.

The methods mentioned in the article can help in most cases, but they are not foolproof. If you have saved your file multiple times since the version you want to restore, the backup file may have been overwritten, and you won’t be able to recover the previous version.
A version control system like Git or Bazaar keeps track of all changes made to your files, allowing you to easily revert to a previous version if necessary. By using these tools, you can better manage your file versions and have more control over recovering previous versions when needed.
You can learn more about using Git in the Git documentation and about Bazaar in the Bazaar documentation.
Ubuntu doesn’t have a built-in file versioning system like some other operating systems. However, you can implement external version control systems like Git or Bazaar to manage file versions effectively.
