in reply to Log regexp

I think this is the problem: \"\S+\"

Maybe these tools will help:

  • The Perl Regex Tester
  • YAPE::Regex::Explain ... Tip #9 from the Basic debugging checklist
    The regular expression: (?-imsx:^(\S+)\, (\S+) (\S+) \- \- \[(\d{2})/(\w+)/(\d{4})\:(\d{2})\:( +\d{2})\:(\d{2})\+(\d{4})\] \"\S+\" (\d{3}) (\d+|-) \"(.*?)\" \"\.*?\" +$) matches as follows: NODE EXPLANATION ---------------------------------------------------------------------- (?-imsx: group, but do not capture (case-sensitive) (with ^ and $ matching normally) (with . not matching \n) (matching whitespace and # normally): ---------------------------------------------------------------------- ^ the beginning of the string ---------------------------------------------------------------------- ( group and capture to \1: ---------------------------------------------------------------------- \S+ non-whitespace (all but \n,
