Look at this thread: https://www.unix.com/unix-for-dummies-questions-and-answers/33759-undelete-files-unix.html

A Unix system is a dynamic system.

Processes are running all the time. Many of these processes create files, even if they are only of temporary nature.

When you delete a file, the blocks which contained the data are available for other processes which create files.

The more time has passed since you deleted the file the bigger the chance is that the data blocks have been reused by another process.

Also, the more activity on the system, the bigger the chance as well.

Theoratically it is possible the UNdelete a file if the data blocks have not been used yet by another process creating files.

However, the procedure to do this is quite complicated and the chance on success is minimal.

Basically you need to be an expert on Unix, go to single user mode and repair everything manually. The chance of corrupting other files in this procedure is far greater than recovering your delete file.

Guess this is a good lesson why you need to backups of your system.
