Please look at How do I post a question effectively?, aka "How (Not) To Ask A Question". It's really unclear what you're looking for.

If you are happy to separate your fields upon spaces:

$line = 'Sat Jun 4 05:56:00 BST 2005 INFO: PD/ZVKK Load: Starting.';
my @fields = split / /, $line;
[download]

Now, @fields[0] contains 'Sat', @fields[1] contains 'Jun' and so on.
