in thread Win32/Linux portability

I thought about something like:

No need for that. See perlintro and use

s/\r\n\z//; 
# or
$line =~ s/\r\n\z//;

    It's been a year, but I still don't get that abbreviated syntax. For example, today I found out that I can easily split strings at each point using 
    @foo=split(/\./,$bar);

    But to split at whitespace I can use 
    @foo=split(" ",$bar);

    [download]
    Why is that and what does it mean? I really don't get it, why doesn't 
    @foo=split(".",$bar);

    work?

      Please read the documentation for split. Twice. Then if you still have trouble, come back and ask.

        I read it more than twice, before. It says "However, this special treatment can be avoided by specifying the pattern / / instead of the string " " , thereby allowing only a single space character to be a separator." To me that means that for one or more ".", "." should work as well, or is there something special about a "." compared to a " "?
