Which is gets pretty annoying after a while, also, if you delete a directory containing a 100 files, you will have to press 'y' a 100 times. This will probably lead to the habit of using 'rm -f', and/or simply pressing y all the time without actually looking at the confirmation message. In any case, it's not likely to prevent any such accidents. For the sake of it: You could use rm -I: quoting the rm man page: -I Request confirmation once if more than three files are being removed or if a directory is being recursively removed. This is a far less intrusive option than -i yet provides almost the same level of protection against mistakes. Output looks like this: # rm -fI * remove 10 files? Would even be better if it would list e.g. 2 or 3 files. A better solution would be to write a script that would move files instead of deleting them. You should name this script to something else than rm, when you're working with a new or foreign system, you will expect rm to move files, instead of deleting them ... and we can all see another disaster coming there... true, sometimes fingers have a memory of their own ;) Another hint would be the 'rmstar' option in tcsh, when set, tcsh will ask confirmation before executing 'rm *'. Note that aliasing 'cp' and 'mv' to 'cp -i' and 'mv -i' is an *extremely* wise idea, in the past I have often accidentally overwritten files that should not have been overwritten, leading to various problems. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Even a filesystem snapshot would have helped in the above scenario. http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/snapshots.html The link above has great info about creating and using filesystem snapshots. If you had one, you could have just mounted the snapshot, and copied over the files/folders you accidentally removed.

Personally, I'd recommend learning from the mistake (we've all done at least once) and being more judicious when entering commands, particularly any 'force' switches, and making regular use of dump(8). That would avoid circumvent the possibility of developing the unwelcome habit of typing 'rm -f' to compensate for the increased level of interaction if aliasing 'rm -i'. Which may be why the OP got into trouble. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
