View 7 Replies View RelatedI attempted to run various cron jobs as root - just general server make-tidy stuff. But if I edit the /etc/crontab file directly, these tasks don't get run. However, if I use crontab -e as root, these jobs appear to work. Any idea why this might be the case? Also, I understand that user cron jobs are stored in /var/spool/cron/<user> (including root). If this is the case, what's the purpose of the /etc/crontab file?
View 5 Replies View RelatedI have been searching for a few hours now trying to figure out the best way to have Ubuntu Server 8.10 copy and replace a file every week.
So for example:
File A (original file)
File B (replacement file)
I would want to copy File B from its location and replace File A each week automatically with out removing or destroying File B.
I've thought of doing a cron since I already have a job set for email piping. but I'm unsure of the best way to complete this task.

I am trying to have the files from /user/directory copy every hour to /backup/user/directory. It would seem that cron or crontab is what I need to use. Looking at previous posts and other documentation only shows how much I don't know. When I type crontab -e I get a blank file I can type into, seemingly using vi as the editor. I have no problem with that but when I type cron -l, I get my text after a message about "Do Not Edit this File". What I am reading just makes no sense, I am not understanding even the most fundamental aspects of cron or crontab. Where I can get the most basic of basic instructions to try to understand this function?
View 4 Replies View RelatedI 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)
Is been a while since I was last here requesting help. Now I need some of that LQ magic. I have a script file that extracts data for a date range, create a zip file for the data and then ftp it to a remote server.

I 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?
I'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
Figure out why this /etc/crontab won't run correctly?
Is it possible that it don't run because the cron deamon is not running? code...
I'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.
