Operating Systems Linux Red Hat Unable to capture value from function Post 303002585 by RudiC on Monday 28th of August 2017 07:40:10 AM

Please become accustomed to provide decent context info of your problem.
It is always helpful to carefully and detailedly phrase a request, and to support it with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

Hadn't it been nice had you presented your problem in sufficient verbosity? Am I guessing right you want to know why the YDATE variable is empty / unassigned? That's because the reading from the pipe is done in a subshell and thus not passed back to the parent.

If people knew what your system is, proposals could be posted to simplify your shell function, or make it more efficient resp.

Weather::Com::DayForecast(3pm)				User Contributed Perl Documentation			    Weather::Com::DayForecast(3pm)

NAME
Weather::Com::DayForecast - class representing a forecast for one day SYNOPSIS
[...] my @locations = $weather_finder->find('Heidelberg'); my $forecast = $locations[0]->forecast(); my $tomorrow = $forecast->day(1); print "Forecast for tomorrow: "; print " - tomorrow it's the ", $tomorrow->date()->date(), " "; print " - sunrise will be at ", $tomorrow->sunrise()->time(), " "; print " - maximum temperature will be ", $tomorrow->high(), " "; DESCRIPTION
Via Weather::Com::DayForecast objects one can access the weather forecast for one specific day. This class will not be updated automatically with each call to one of its methods. You need to call a method of your Weather::Com::Forecast object to get updated objects. CONSTRUCTOR
You usually would not construct an object of this class yourself. This is implicitely done when you call the "day(number of day)" or the "all()" method of a Weather::Com::Forecast object. METHODS
date() Returns a Weather::Com::DateTime object containing the date the forecast is for. high() Returns the maximum temperature that will be reached at daytime. For day 0 (today), this will be 'N/A' when it's after noon... There is a bug in weather.com's date and time mathematics: If you are asking for a location's forecast day 0 and it's short after midnight, day 0 will be "yesterday" and you'll get both, yesterday's daytime forecast and night forecast! I have not investigated this issue further, yet. If anyone has, please inform me! low() Returns the minimum temperature that will be reached at night. sunrise() Returns a Weather::Com::DateTime object containing the time of sunrise. sunset() Returns a Weather::Com::DateTime object containing the time of sunset. day() Returns a Weather::Com::DayPart object with all data belonging to the daytime. For day 0 (today), this will be "undef" when it's after noon... There is a bug in weather.com's date and time mathematics: If you are asking for a location's forecast day 0 and it's short after midnight, day 0 will be "yesterday" and you'll get both, yesterday's daytime forecast and night forecast! I have not investigated this issue further, yet. If anyone has, please inform me! night() Returns a Weather::Com::DayPart object with all data belonging to the night. AUTHOR
