[BNE-PM] My 0 liner

[Don.Simonetta at mincom.com]

I don't usually use perl for one liner commands (except to check syntax
of things I'm trying out). So I don't really have much to contribute.
But I remember an example I'd seen in a tutorial. I looked this up again
today and realised I can do something really powerful without even
writing 1 line of perl code! Here is my simplified version of the
example:

perl -p -i.bak -e '' <file list>

This will take a list of files and create copies of them with (in this
case) a ".bak" extension.
