Re: How to write a perl script to work on many OS(s)

Use forward slashes (aka virgules). Generally, Perl will treat / as the path delimiter in Windows; see here. Quoting: "Since all DOS and Windows versions since something like MS-DOS 2.0 or so have treated / and \ the same in a path, you might as well use the one that doesn't clash with Perl--or the POSIX shell, ANSI C and C++, awk, Tcl, Java, or Python, just to mention a few. POSIX paths are more portable, too." (perlfaq5)

Note that different shells have different quoting conventions, and different methods of determining when variable substitution should take place.

Forward slashes generally work in Perl MSWin32. There are a few corner cases where this doesn't work. ALSO... don't forget that windows shares need to start with two slashes... I believe File::Spec::canonpath will collapse them down to one, causing problems.	[reply]

Thanks; I wasn't aware of File::Spec::canonpath collapsing leading double slashes to one. I'll watch out for that in the future. emc Any New York City or Connecticut area jobs?

Fine for *nix and DOS/Windows, but not so good for Mac and others maybe? DWIM is Perl's answer to Gödel	[reply]

For Mac OS 9 and older you should use ":" as a path separator, but Mac OS X uses "/" just fine.	[reply]
