graylog2 - Regex to find spaces between quotes in Graylog -


working on input extractor issue iis logs using "advanced" iis login tool collect more basic logs provide. it's adding double quotes , spaces many of fields , trying extractor correct this. beginning of example message:

2016-02-08 16:46:35.957 "site" "source" xx.xx.xx.xx /blah/etc/etc/file.ext - 80 - "xx.xx.xx.xx" "http/1.1" "mozilla/5.0 (windows nt 6.1; wow64; trident/7.0; yie11; rv:11.0) gecko"

we've written extractor remove added quotes before running through other extractors populate fields, etc., want replace spaces between quotes + before match old logging style.

can point in right direction this? closest i've come far catching " " between site , source , replacing using "([\s]*)". result:

2016-02-08 16:46:35.957 "site+source" xx.xx.xx.xx /blah/etc/etc/file.ext - 80 - "xx.xx.xx.xx+http/1.1+mozilla/5.0 (windows nt 6.1; wow64; trident/7.0; yie11; rv:11.0) gecko"

i can't seem spaces between quotes.

any appreciated. thanks.

further clarification. portion of string:

"mozilla/5.0 (windows nt 6.1; wow64; trident/7.0; yie11; rv:11.0) gecko"

should be:

"mozilla/5.0+(windows+nt+6.1;+wow64;+trident/7.0;+yie11;+rv:11.0)+like+gecko"

everything else should remain same spaces inside of quoted section of string.

is possible regex?

i'm afraid regular expressions not best tool this. have "count" quotes determine whether space within quotes or not.

you can try (python):

text = '2016-02-08 16:46:35.957 "site" "source" xx.xx.xx.xx /blah/etc/etc/file.ext - 80 - "xx.xx.xx.xx" "http/1.1" "mozilla/5.0 (windows nt 6.1; wow64; trident/7.0; yie11; rv:11.0) gecko"' escaped = "" count = 0 c in text:     if c == '"':         count += 1     if c == " " , count % 2 == 1:         escaped += "+"     else:         escaped += c

afterwards, escaped this:

2016-02-08 16:46:35.957 "site" "source" xx.xx.xx.xx /blah/etc/etc/file.ext - 80 - "xx.xx.xx.xx" "http/1.1" "mozilla/5.0+(windows+nt+6.1;+wow64;+trident/7.0;+yie11;+rv:11.0)+like+gecko"

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
