Apart of unix perms are there other protection for don't remove or overwrite files?By example:Restringing dirs than rm can delete.Overwrite protection when I made cat >file instead of cat >>fileOverwrite protection option for default for all commands cp, rsync, etc. No configuration command by command.If there are a trash system, substituting overwrite by removing file and create a new one with same name.Delayed delete.
What methods for overwrite protection and accidental removing are there?
