I have .bcast5 is in
/root/: Can I delete this .bcast5? How do I it?
To delete the root .bcast5 directory and its contents (assuming it is the same in Arch which it should be). You always have to be
extremely cautious when doing this. The "-ri" is recursive and it prompts you for each file to reply with "y" or "n". If you do minimum cinelerra work while logged in as root, there should not be that many files. If you are absolutely sure you will never make a mistake (and who is?) you can use "-rf" instead which forces the delete without prompting.
