How do I regain my source after gcc -o mistake order

Question

I run "gcc -o program.c program" instead of "gcc program.c -o program" by mistake and now I lost my source (program.c). Is there any solution to regain my source or it is definitely lost?

Answer 1

Unless you have a backup, it is gone.

To prevent that from happening in the future, you could use make:

~$ make program
