prevent deleting important files


HI Friends,

Is there anyway to prevent deleting important fills, this is for ROOT user
Ex= /home/Script/
there is so many scripts inside this directory, so i want to prevent accidentally deleting files inside this. Is there any way to do this, or give warning before deleting for ROOT user.

You can always mark them "immutable" (see documentation on chattr).

Once marked they cannot be deleted or altered without first removing the immutable flag.

A few things pop to mind, depending on what you need.

If you almost never need to change the script, you could burn to a CD or DVD. If you change them every now and then, you could probably get away with a rewritable disc.
You could also use an SD card. Most SD cards have a "lock" switch on the side. When activated (IIRC) it prohibits anything from writing to it, but it can still be read.
Also, you could have a separate partition on your hard drive, and mount it as read-only.

However, even if you did manage to erase the script, you could always restore from your backup, right???? But seriously, if the scripts are important, it would be very unwise to have only one copy of them.

Hope this helps!

Apart from the immutable flag, you could also chown root and chmod 000 to make it invisible to pretty much everybody. Root could still delete it though.
