wget - Cron output to nothing -

-

i've noticed cron outputs creating index.html files on server. command i'm using wget http://www.example.com 2>&1. i've tried including --reject "index.html*"

how can prevent output creating index.html files?

--2013-07-21 16:03:01--  http://www.examplel.com resolving example.com... 192.0.43.10 connecting www.example.com|192.0.43.10|:80... connected. http request sent, awaiting response... 200 ok length: 0 [text/html] saving to: `index.html.9'       0k                                                        0.00 =0s  2013-07-21 16:03:03 (0.00 b/s) - `index.html.9' saved [0/0]

normally, whole point of running wget create output file. url http://www.example.com typically resolves http://www.example.com/index.html, creating index.html, wget command doing job.

if want run wget , discard downloaded file, can use:

wget -q -o /dev/null http://www.example.com

the -o /dev/null discards log messages; -o /dev/null discards downloaded file.

if want sure wget writes stdout or stderr discarded:

wget -q -o /dev/null http://www.example.com >/dev/null 2>&1

in comment, you're using wget command "trigger items on cron controller" using codeigniter. i'm not familiar codeigniter, downloading , discarding html file seems inefficient. suspect (and hope) there's cleaner way whatever you're trying do.

when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

time series - R growth rate calculation week over week on daily timeseries data -

-
i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
