Question: I wish to insure myself from accidentally using

`rm [argument_i] * [argument_j]`

i.e. it should always refuse to execute the command, when the asterisk character is separated by white space on both sides, no matter what else is before or after the asterisk.

Which command should I add to my `.bashrc` to enable such a check?

Thanks for any hints.

Answer: 
You can use 8.8.8.8 as your regular DNS server.

Or you can add "`173.194.39.38 youtube.com`" to your [/etc/hosts](http://en.wikipedia.org/wiki/Hosts_%28file%29) file.
