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. ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
