php - Controlling Daemon Software via Shell Script with Cron -


i installed "the fat controller" software (http://fat-controller.sourceforge.net/) on server (ubuntu 14.04.5 lts) daemonise php script need run constantly.

it works perfectly, @ moment have control shell manually following commands.

starting

/etc/init.d/fatcontrollerd start

stopping

/etc/init.d/fatcontrollerd stop

is running?

/etc/init.d/fatcontrollerd status

basically, want setup shell script call cron same process manually, automatically every minute (check if it's running --> if is, nothing --> if not, start it).

when type "is running" while running command in shell, response "running". how can write shell script send "is running" command , run "start" command if, "is running" not respond "running"?

i inexperienced in shell, did previous daemon script work (that failed horribly). know how hooked cron, can't find syntax on how run these commands automatically, make decision , run command if necessary.

you can write script in php too, , running external process , output can use shell-exec function, can use like:

$output = shell_exec("/etc/init.d/fatcontrollerd status"); if ($output == "running") {     // need do!! }

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

python - ValueError: No axis named 1 for object type <class 'pandas.core.series.Series'> -

i´m new programming. i´m trying use scipy minimize, had several issues , gotten through of them. right code, i'm not understanding why i´m getting error. par_opt = so.minimize(fun=fun_obj, x0=par_ini, method='nelder-mead', args=[series_pt_cal, dt, series_caudal_cal]) not enough info given op, somewhere in code it's specified operate data frame column (axis=1) on object pandas series. if code typically works occasional gives errors, check degenerative cases data frame may have 1 row. pandas has nasty habit of guessing want -- may decide reduce 1-row data frame series (e.g., apply() function; can disable using reduce=false in there). add line of code check object isinstance(df, pd.dataframe) or else convert offending pandas series data frame, s.to_frame().t problems had deal with.
