Ubuntu :: Crontab - None Of Job Apparently Running
Jun 1, 2011I have the following set up in my crontab:
Code:
# crontab -l
# m h dom mon dow command
*/5 * * * * /usr/bin/perl /usr/local/bin/perl/managed_arp_data.pl >> /var/log/arpdb.log
*/5 * * * * /usr/bin/perl /usr/local/bin/perl/infoblox_fixed_sync.pl >> /var/log/crossref.log
00 23 * * * /usr/bin/perl /usr/local/bin/perl/infoblox_host_sync.pl >> /var/log/host_sync.log
0 * * * * /usr/bin/perl /usr/local/bin/perl/infoblox_excl_sync.pl >> /var/log/excl_sync.log
None of these jobs is apparently running, however they did run on the 31st (yesterday), but not on the 30th or any other day during the last 10 days that I have logs for. I think I've set cron to run at log level 1, but I don't know where that log goes, I don't see anything like /var/log/cron
So, couple questions:
* If I do something like "sudo -s" to get a root prompt and then do a "crontab -e", which user does that crontab get executed as?
* Where should I look for cron logs?
* Anyone know why a job would run on the 31st, but not any other day?

Software :: Crontab Entries Running On Even And Odd Weeks
Sep 24, 2010I'm using crontab to start and stop music playback (its like start and end of a brake in school). The problem is that some of the entries should be run on even weeks and some on odd.
exp:
This should be played on even weeks
00 08 * * * audacious -p
10 08 * * * audacious -u
and this on odd
05 08 * * * audacious -p
15 08 * * * audacious -u
There are about 20 entries for even and 20 for odd. I found here on the forum that maybe this should work but for it is not working for me
00 08 * * * [[ $(expr `date +\%W` \% 2) = 0 ]] && audacious -p
If I put it like that its not working at all

View 4 Replies View RelatedUbuntu Servers :: After Using Crontab With /etc/crontab / Giving Error "can't Find Command Root"?
Aug 26, 2010I have a question about using crontab with /etc/crontab...
I had a cron job that I needed to run as root. At the time I thought that sticking it in /etc/crontab would be a good idea. However, I used the crontab command to edit /etc/crontab, which I guess is not standard procedure? Specifically, I configured /etc/crontab as my local user's crontab (i.e. sudo crontab /etc/crontab) then added my cron job as I would a local user crontab (i.e. sudo crontab -e).
Originally, my cron job looked like this:
30 * * * * root /my/batch/script &> /dev/null
After adding the new cron job I started seeing errors. Something to the effect of "can't find command root" or something similar. So I removed the 'root' user definition from the cron job and the job started running fine. However, because this is /etc/crontab, there are other system related cron jobs that have been defined to run under the root account (e.g. "17 * * * * root cd / && run-parts --report /etc/cron.hourly" runs as root, etc.). So these pre-existing system cron jobs, which up until now have been running smoothly, are now generating "can't find command root" errors. But I think that the system cron jobs _are_ successfully being run someplace because logrotate seems to be working.
So what I _think_ is happening is that /etc/crontab is being run twice: once as the system crontab, and once as my sudoed local user's crontab. When I run crontab -l I see nothing, but when I run sudo crontab -l I can see the contents of /etc/crontab. I am reluctant to delete my sudoed local user's crontab, because then in the process I would be deleting the system crontab, and I do not know how I should restore the system crontab's contents. (I am still not sure as to the most appropriate way to edit the system crontab).
How can I get out of this mess? I want /etc/crontab to go back to the way it was before--running _once_ as the system crontab. As for my new cron job, I'm willing to reconfigure it anywhere so long as I am still able to run it as root. Any ideas? (I am using Ubuntu 8.04 Server LTE)

Ubuntu :: Schedule A GUI App With At Or Crontab?
Mar 2, 2010I want to schedule a Java program to run at a certain time, which will open a GUI progress monitor while it runs, and then terminate when it's done. I can execute it fine from the command line, but I it doesn't seem to work when I schedule it with crontab. In fact, I can't make any gui by scheduling it, not even something like gedit or firefox.
I know it's pretty rare that someone would want to do this, but is there any way to schedule a GUI app?
Ubuntu :: How To Restart Gdm From Crontab
Jun 16, 2010I'm having problems trying to restart gdm from crontab and I'm not sure what I'm doing wrong. Basically what I want to do is a 'logout' every morning before I get to work so that by the time I get to my computer I would just have to log back in and have a fresh gnome session.
The command I'm using to restart gdm is:
Code:
/usr/sbin/service gdm restart
If I run this command from a terminal as root it works.
To edit my crontab file I'm doing:
Code:
sudo crontab -u root -e
And adding the following line to it:
Code:
25 08 * * 1-5 /usr/sbin/service gdm restart
My understanding is that this should restart gdm every day of the work week (Mon-Fri) at 08:25. But for some reason this is not happening.
I also checked that my cron deamon is running by:
Code:
~$ service gdm status
gdm start/running, process 27156

Ubuntu :: Rsync - .sh And Crontab
Feb 14, 2011I'm currently trying to have crontab to automatically backup files from ramdisk. It works perfectly when I run it myself by simply cd:ing to scripts directory and type ./save_world.sh.
The problem is, that crontab DOES (at least it looks like it) run that command every one minute. /var/log/syslog does show it executing that line every one minute without any errors. I'm currently very confused what I did wrong here. I have tried rebooting, fiddling with crontab line, tried sudo crontab -e but nothing seems to work.
My script is called save_world.sh and it is located in /home/phoe/minecraft/rpg/
