Never use rm's -f flag while operating as the root user. Never. Replace with -i until you are absolutely 100% certain the script you're writing works as expected. Always doubt yourself; be humble.

The -I flag is a bit more friendly; one may safely alias rm to rm -I and not even notice on the common case (deleting a single file).

I use a script that moves a file to a ~/.trash directory when I use rm. If I am sure I want to actually delete a file permanently I just use /bin/rm.

But that's also the best way to becoming careless about typing "rm".

And the day you will be ssh'd on another computer, you may forget that you are using a command which is really deleting.

Sounds like a great way to fill up your disk to me.

You could use a cron job that removes the "deleted" files after some period, such as 30 days.
