[vdr] Re: vdr Restarting Tool (cron Job + Perl)

[Markus Kalb <Markus.Kalb@gmx.net>]

Hi

i just daw that the mailinglist has stripped my attachment so here is
the perl script i wrote:

ciao markus 

#!/usr/bin/perl -w

use File::Basename;

#
# Here you have to change the path to get it working
# as we will be using the runvdr script make shure it's
# also located in that dir!!
$vdrPRG = "/PathOfYourVdrProgrammDir/vdr";


$vdrDIR = &dirname($vdrPRG);

#
# the file where you want some log info writen to
$vdrCronLOG = "/var/log/vdrCronJob.log";


#
# First we check if the vdr is still running. I'm doing that
# with the ps tool as i not yet found out how that would be
# done in perl ;)
open (PS,"ps -ef | grep ".$vdrPRG." |");
@ps = <PS>;
close(PS);

# so now we have some lines like
# vdrusr 20037 20035  0 01:17 pts/2    00:00:02
/PathOfYourVdrProgrammDir/vdr -w
# in that array @ps if the vdr is still running and if it's not
running there
# should be no lines and so we have to check if the array is empty
if ( @ps == 0)
  {
    # lets restart the vder using the run script
    system($vdrDIR."/runvdr &");
    # now let's write somethin into the log file
    open(LOG,">>".$vdrCronLOG);
    print LOG "Restarting vdr with checkvdr.pl script\n";
    close(LOG);
    # put the date into the log file using the date programm from
linux
    system("date >> ".$vdrCronLOG);
  }
