Recovering a moved file in ubuntu

Solution 1:

If the original file was moved, then, no. The only existing copy is the one you moved and edited in the mean time. If you make backups regularly, you may be able to recover an earlier version from the backup. Else, it would require advanced data recovery to retrieve traces of the original file - in as far as the disk space has not been overwritten. Depending on the complexity of the changes to your file, (an attempt at) recovery of the original file may not be worth the time and the trouble.

Photorec is a relatively accessible tool to recover deleted files, which you could attempt if this is really critical. To be safe, you would need to work on a binary disk image of the partition. Only making that copy already will take substantial time.
