Although the Perl language is portable among platforms, most of the scripts used for system administration leverage platform-specific resources. And scripts meant for Solaris might use Solaris-specific pathnames and system commands that may have not equivalents on Linux®. This article gives you a roadmap for code remediation to help you port a Perl script from Solaris to Linux when direct mapping isn't available.
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
