ruby - How do you use logrotate with output redirect? -


i'm running ruby script logs http traffic stdout. since wanted logs persistent, redirected output log file ruby ruby_script.rb >> /var/log/ruby_script.log. however, logs getting large wanted implement logrotate using following:

"/var/log/ruby_script.log" {   missingok   daily   rotate 10   dateext }

however, after running logrotate --force -v ruby_script "ruby_script" name of logrotate.d configuration file, no new file created script write to, , writes rotated file instead. i'm guessing behavior happens because file descriptor passed >> sticks file regardless of moving it, , unrelated filename after first call. thus, question is, correct way achieve functionality i'm looking for?

take @ option copytruncate.

from man logrotate:

copytruncate: truncate original log file 0 size in place after creating copy, instead of moving old log file , optionally creating new one. can used when program cannot told close logfile , might continue writing (appending) previous log file forever. note there small time slice between copying file , truncating it, logging data might lost. when option used, create option have no effect, old log file stays in place.

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). ...
