In this case, especially when you care about portability
and interoperability, I'd like to suggest reading the
following two articles about how to deal with filenames:

David A. Wheeler:

Fixing Unix/Linux/POSIX Filenames:
Control Characters (such as Newline), Leading Dashes, and Other Problems

http://www.dwheeler.com/essays/fixing-unix-linux-filenames.html



David A. Wheeler:

Filenames and Pathnames in Shell:
How to do it correctly

http://www.dwheeler.com/essays/filenames-in-shell.html



Additionally, it's worth knowing the _difference_ between
the Bourne Shell and the BASH extensions, because those
two shells aren't the same, even though there are people
who seem to think this. When the "dash" shell enters the
stage, the fun is about to start. ;-)
