Removing magic numbers

[Alan Jackson]

My son has a friend who ftp'd a bunch of perl scripts from Windoze
to a Linux box for CGI stuff. Windows stupidly (or purposely?) screwed
up the magic number in the files so that they are not recognized
as perl scripts and won't run.

He figured out how to use hexedit to get rid of the magic number and fix
the problem, but now we're wondering about a better solution - a way to
script it and clean up the files automagically. We could write a little
C program, but surely there is another way out there somewhere?

All we need is a way to delete the first 3 bytes from a binary file.
