I dl ganttproject but could only delete a task and enter it again rather than editing the start and end dates. BTW I really would like to be able to enter start and end hours on some tasks. Any recommendations of open source Java or Scala schedulers which could do better .

View 6 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)

View 2 Replies View RelatedServer :: Causing Crontab To Not Email Blank Emails
Aug 3, 2011I've currently got a crontab line that looks like the following:
Code:
*/5 * * * * /usr/bin/php -q /etc/backend/cron.php | mail -s "Cron script output" whiteydude@gmail.com
The script works fine - it runs every 5 minutes and checks if certain environmental variables are set in place - if they are, it prints an output. If they're not, it dies.
The problem is that when it dies, it still sends me a blank email - one every 5 minutes, every time the cron job runs.
telling it not to send if it's blank?
I'm assuming some type of dirty awk script could do this, but I don't really know my shell well enough to do that.
I'm not good at putting these things into words, so let me write some psuedo code to explain what I mean:
Code:
*/5 * * * * /usr/bin/php -q /etc/backend/cron.php | if (STDOUT != '') { mail -s "Cron script output" whiteydude@gmail.com }
EDIT: Unfortunately I'm running on CentOS, so I can't use mail -E . Apparently that's a FreeBSD thing.
Server :: Crontab Fails But Command Line Works ?
Feb 19, 2011Having an odd problem running a mysqldump via crontab. I have the script running on other servers and they work fine, so not sure how to actually troubleshoot, but the script looks like the following;
If I run it as a cronjob as root, it finishes in a second and a 20k file is there. If I run it from the command line as root it does the backup (takes a few minutes) but does complete the backup and can be unzipped and read successfully.

View 2 Replies View RelatedServer :: Rsync Execution - With Crontab - Have Given Full Path To Rsync Too
Apr 12, 2011I have a tiny shell script to rsync files between two servers and remove the source files.
This script works fine, when it has been initiated manually or even when the rsync command is executed on the command line.
But the same script doesn't work, when I try to automate it through crontab.
I am using 'abc' user to execute this rsync, instead of root, as root login to servers are restricted in all of our servers, by us.
As I mentioned earlier, manual execution works like charm!
When this rsync.sh is initiated through crontab, it runs the first command(chown abc.abc ...) perfectly without any issues. But the second line is not at all executed, and there is no log entry i can find at /mnt/xyz/folder/rsync.log.

I want to limit the touchscreen USB keyboard input only to a specific set of apps.Is there a program which can help me detect which USB port or device the code is coming from? Or someway I can map one keyboard to send a different set of codes? The device is using Linux.
