Run state on sunset sunrise

Flav · Post by **Flav** » Tue Feb 09, 2010 9:37 am

Hello this is a little script for run ZM on different state whithe the sunset/sunrise

1) Compile sunrise.c

  Compile:

     gcc -o sunrise -Wall -W -O2 -s -pipe -lm sunrise.c

  or for debug output

     gcc -o sunrise -DDEBUG=1 -Wall -W -O2 -s -pipe -lm sunrise.c




  This can also go in a batch job to calculate the next
  20 days as follows:

    #!/bin/bash
    lat=39.95
    long=75.15
    for (( i=0; i <= 20; i++))
    do
     ./sunrise    `date -d "+$i day" "+%Y %m %d"` $lat $long
    done

2) Find your location (GPS or in google maps/earth)
3) Create script like this

Code: Select all

#! /bin/bash 
# /root/timeup  
# Author: fvillant 
# Date: 2007.10.10.
# Recuperation du lever et du coucher du Soleil a Porto-Vecchio pour la date du lendemain

/root/sunrise `date -d "+1 day" "+%Y %m %d"` 41.41 -9.22

4)Edit /etc/crontab and fix line where you enter the command line you nerver add something before !!!!!!!!!!!!!!
4.1) At the end ad the commande line 30 23 * * * root /root/editcron

5) Create a script /root/editcron

Code: Select all

#!/usr/bin/perl -w
#
# 28 Janvier 2010 Creation Flavien Villant
# Edition crontab pour modification sunset
# sunrise selon le jour et l'heure la la
# 
#
#
#
system("/root/timeup > sun.txt");
open(FILE,"sun.txt");
@arr = <FILE>;
for $line (@arr) {
chomp $line;
# Recuperation des horaires
$sunriseH=substr($line,21,2);
$sunriseM=substr($line,24,2);
$sunsetH=substr($line,51,2);
$sunsetM=substr($line,54,2);



$sunsetrise = "# Mode Jour/Nuit Zoneminder ".$Line." NE PAS DECOMMENTER";
$jour = $sunriseM." ".$sunriseH." * * * root /usr/bin/zmpkg.pl Day";
$nuit = $sunsetM." ".$sunsetH." * * * root /usr/bin/zmpkg.pl Night";

}

close(FILE);




open(FILE,"/etc/crontab");
my @crn = <FILE>;
close(FILE);

$crn[23] = $sunsetrise;
$crn[24] = $jour;
$crn[25] = $nuit;

open(FILE, ">/etc/crontab") || die "Erreur E/S:$!\n";
foreach my $ligne (@crn) {
    chomp $ligne;
    print FILE "$ligne\n";
}


system("chmod 754 /etc/crontab");
system("chmod +x /etc/crontab");

exit;

In my crontag the line with the script are the 24 and 25 but in pearl the first line is the 0
BEWARE NEVER AD LINE BEFORE THIS
