Perl is a programming language
-pi  < used for editing a file, I foget what each is.  Do "man perl" for 
more info.

-e < execute the following

"s/#//" <= swap # for '' (nothing)

filename to edit.

Basically it is a quick way to edit a file, with out using pico / vi ... 
that way it can be automated.
