in reply to Log regexp

I took this:

$_ = qq{, - - [21/Apr/2012:04:35: +01 +0200] "GET /seo/vbseocp.php HTTP/1.0" 404 300 "-" "Internet Explo +rer 6.0", - - [22/Apr/2012:04:00:43 + +0200] "GET / HTTP/1.0" 200 10211 "" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; +)"}; m/^(\S+)\, (\S+) (\S+) \- \- \[(\d{2})\/(\w+)\/(\d{4})\:(\d{2})\:(\d{2 +})\:(\d{2})\+(\d{4})\] \"\S+\" (\d{3}) (\d+|-) \"(.*?)\" \"\.*?\"$/; print map { "[$_]\n" } $1,$2,$3,$4,$5,$6,$7,$8,$9,$10,$11,$12,$13;

And tweaked your expression down to this:

m@^(\S+?), (\S+) (\S+) - - \[(\d{2})/(\w+)/(\d{4}):\s*(\d{2}):(\d{2}): +\s*(\d{2}) \+(\d{4})\] ".*?" (\d{3}) (\d+) "(.*?)" "(.*?)"@; # 1 2 +3 4 5 6 7
  1. I made \S non-greedy, to not gobble up the comma.
  2. I changed one literal space to \s* (Your example doesn't have spaces.)
  3. Same as #2.
  4. I changed "greedy non-whitespace" (which was failing b/c the string within has whitespace) to "non-greedy non-quotes"
  5. I don't know what you intended with "(\d+|-)"...
  6. Again, non-greedy non-quotes - I think that's what you wanted.
  7. I removed the end-of-line anchor ($), because you aren't currently matching to the end.

Also note I changed the delimiter to something NOT in your content, so it doesn't need to be escaped. And I did NOT escape these other characters: -:"
