Re: cronjobs
Ben,
Than you so much, this really is what i needed.
If i have put it together with some scripts i will put it on the wiki.
This way we can wake-up our FR when a cron job is due.
Again thanks a lot.
Kind regards,
Ed

No, i had no idea i could !
But now that i try it i get:
Can't call method get_next_execution_time on an undefined value at
./ff.pl line 11.
Can you make an example perl script? a real simple one?
Thanks !
Kind regards,
Ed

Hi Alexey and all the others
I did take a look at perl, but i am a real perl noob.
This is what i have so far:
#!/usr/bin/perl
use Config::Crontab
$event = new Config::Crontab::Event( -data = '*/5 3 * * 5,6 /bin/blech' );
print $event-minute . \n;
print $event-hour . \n;
print $event-dom . \n;
print $event-datetime . \n;
print $event-command . \n;
print $event-dump . \n;
And if i run that i get:
*/5
3
*
*/5 3 * * 5,6
/bin/blech
*/5 3 * * 5,6 /bin/blech
Perhaps i am missing the obvious here.
Is there someone out there who can make a script that can read a
crontab line and give the time and date of the next time it will be
executed ?
output in the form:
secs_since_epoch,-mm-dd,hh:mm,command would be *great*
Many thanks in advance,
Ed

cronjobs
