First I thought cp would be aliased to 'cp -i' (interactive) but I don't find anything of such sort. The active aliasses are: [kebil@midas ~]$ alias l. ls -d .* --color=tty ll ls -l --color=tty ls ls --color=tty vi vim So, maybe you're trying to delete files from which you are not the owner (eventhough you own the directory)?

I was thinking the same... I think that the -f option "overrides" the -i option with the rm and mv commands, but not the cp command for some reason. So it might be a bug (or a feature) in either the cp command or the rm and mv commands... or we are simply overlooking something. Anyone have any idea about the internal working of the cp command when overwriting files? Does it first remove the file (by removing the inode in the file system) or does it work in other mysterious ways? Michiel lieven sterck wrote:

btw, the man-page of cp is pretty weird... option -f/--force : if an existing destination file cannot be opened, remove it and try again why the hell would you want to open the destination file? I think the meaning of force is slightly different between cp and rm and mv... That seems a likely explanation at least. Anyway, the command "unalias cp" indeed allows you to copy without prompting. So i think it is rather a difference in word definitions than technical aspects. Michiel Michiel Van Bel wrote:
