View 2 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)

Oct 20, 2010My laptop's clock (Acer Extensa 5220) seems to be slow. I've corrected it 5 minutes forward last week and now have just corrected minute forward again. Is there a program [apart from time servers] to correct clock properly, for example, by shifting it a bit every hour? Is there already a program to put it to crontab or I should hack up a script? Or I should check more things?
I have found that HW clock is right, but system time is slow: about a second each 2.1 hours.

General :: Commented Out Lines In Crontab Still Run?
Sep 20, 2010Silly question here. My crontab looks like this:
Quote:
0 22 * * * /usr/sbin/logrotate /var/log/VRTSralus/VRTSralus.logrotate
#0-59/10 * * * * /root/memmon.sh >> /var/log/memmon.txt
0 8 * * 1 /root/SHC.sh
#0 21 * * * /root/scripts/ralus_restart.sh > /dev/null 2>&1
As you can see two of the lines are commented out. However, both commented out commands are still running. I get emails stating that the RALUS agent restarted (another mystery since it's supposed to go to dev null according to the line above), and I can see that the memmon script is also running daily. Am I missing a step? Some other place I should be looking? Commenting out lines in your crontab is pretty much a no-brainer, so I appear to have less than no brain as this is a mystery to me.

General :: Crontab Shutdown Not Working?

I have tried a variety of alternatives such as "/sbin/shutdown -h" and "runlevel 0", they all behave the same way

Nov 22, 2010I have a quick question involving crontab and a script I want to run with it.

The script will run when you enter 'y' or 'yes' and then press enter.
I'm trying to give that input via another script which runs the first one and then waits for the prompt to input a 'y'.How can I make a script which waits for a prompt and then gives it input?
General :: Difference Between Manual Run And Crontab Run?
Jan 15, 2010My predecessor wrote a perl file that is run manually twice a month to send a set of emailed reports to one of our clients. My boss has requested that I look into automating this; it seemed simple enough, and I thought I had it set up, but I'm running into a rather strange problem.
Both the emailing program (in perl) and the report files themselves are kept on a Novell server reached from our Linux box via /mnt/srv/path/to/file/. From the linux box, I can see and manipulate them fine. The files are displayed as having 755 permissions across the board. The Linux box itself is running SuSE 9.3.
A manual run of the emailing program works fine; the files are sent out as expected. However, when I tried to set up a crontab entry for this, I'm running into trouble. I manually edited /etc/crontab to include a line setting the program to run at '0 21 * * 1,2,3,4,5'. The program itself runs fine, but errors out every time it tries to attach a file; the error message is one that various perl sites indicate means 'could not read the path to this file'.
What's the difference between a cron run and a manual run? What are some possible reasons the former fails and the latter works?
