Some of you are probably not going to believe this, but I've been using Linux for like four years and have never used cron for task scheduling before. Now I want to and I'm not sure how to do it. Could somebody link me to some good info? The results of a Google search were kinda confusing.
View 5 RepliesI was searching for many time but haven't found any solution. Cron would be great, but it allows only steps in range 1-59 minutes. Is there any mode to run something exactly every 73 minutes?
The second i need (the same problem) to run program little more than every 12 hours, it might be in steps of 12 hours and 4 minutes (but 13 hours is much too much).
I'm trying to get my backup script to run every week, but as a normal user, and not as root as it is done when the script is placed in /etc/cron.weekly. Anacron fits my needs in the sense that it doesn't require my computer to always be on, as opposed to cron, and will just run my script when it can, but at the most each week. Cron fits my needs in the sense that I can run the script as the user I am logged in as. The particular script backs up my home directory with rdiff-backup, and it is very convenient that I am the owner of that backup, since when root performs the backup, I am unable to browse my own backup files and must use "sudo" to do this.
Is there a way to let me use the feature of anacron that allows my computer to not always be on, but still get a weekly execution, and also run the script as a normal (non-root) user?
I have a cron job to schedule the task on the third sunday of the month.I saw the previous threads but didn't find any solution.

Is there a way to specify a timezone for a specific job in the crontab file? If so what would be the format for Sydney so it follows the daylight savings time changes? Right now I will just change the cron schedule when Sydney goes on and off DST.

Code: Select allcrontab -e
Then in the editor, I typed the following line at the bottom of file. I also made the necessary carriage return after this line.
Code: Select all@reboot gtk-launch ts3 /usr/share/applications
Then I pressed ctrl+o to save it.
After I put these commands in, I did the following command to troubleshooting this issue, see below.
Code: Select all$ crontab -l
no crontab for server
$ps -ef | grep cron | grep -v grep
root 532 1 0 21:35 ? 00:00:00 /usr/sbin/cron -f
But after I reboot and nothing happens, the application doesn't start.

The individual window "buttons" themselves keep changing size - flashing even, and the space between them also changes. It is driving me nuts! The little system tray(?) icons no longer appear in the system tray, but all stacked on top of each other in the top left corner.

I'm going to rebuild a computer for a friend of mine. I'm going to install 12.2 in it and wanted to see if there was a way to install patches automatically from a cron. I don't think slackpkg can do such thing as a cron, correct? For anyone that set up a Slackware box for someone with little Linux knowledge, how did you handle the ability for the person to update the box?

View 4 Replies View RelatedI messed up when I chose my server for slackpkg updates, I chose one for Slackware13 rather then Slackware13 64. This caused some issues when I accepted the updates. I got a fair bit up and running again, but one thing that seems to be messed up is my cron.hourly scripts. I am not entirely sure what happened, but they are not running.
View 2 Replies View RelatedBy default, cron jobs are scheduled to run at 4:40 IIRC. I have my computer set to suspend after half an hour of inactivity so, except for some all-nighters, pretty much every day at that time my PC is suspended. What happens to the cron jobs? I don't suppose they run while the suspension is in effect. Do they get run when the computer wakes up or does cron wait until the next day at 4:40 to run the jobs?
View 5 Replies View RelatedI have my task list in evolution (mainly so it can sync with my phone and online task list) but I always forget to look at the task list. Is there an application or plugin which periodically displays the contents of the tasklist or even better, it briefly displays the most urgent/important tasks when I login? Or anything else which automatically displays the most important tasks. Currently I have to open the task list and look at them (which I usually forget). I do not mean some kind of alarm when the task is due but more a daily reminder of what to do.
View 3 Replies View RelatedCan anyone tell me how i change the default domain name for cron?everything i cron runs it emails from and to user@com.com
this leaves me with a massive list of failed mails in postfix.i have mailto on my main crontab but i cant do it on all of them.
I have added some executable scripts to /etc/cron.daily but don't get the stdout/stderr output from them as mail (or anywhere else I have found). At least one of them is running (because I can see that it has added a file to the disk).
The peculiar thing is that I do get the output from /etc/cron.daily/0logwatch (part of the logwatch package) as an email each day.
The MAILTO line in /etc/crontab is "MAILTO=root" (unchanged from default). Same for /etc/anacrontab.
I do have an alias at the end of /etc/aliases which redirects root's mail to my own account, but this alias works fine for mail I send manually. (It also appears to work fine for the output from the file /etc/cron.daily/0logwatch.)
It seems that cron is not upgrading my Ubuntu 8.04 LTS Server, no GUI installed. I changed /etc/crontab and watched apt running:

showed communication with canonical sites,

I put in my cron entries to run my backup script which rsyncs my data to my 2nd drive, however on a hunch I checked my backup drive which mounts automatically via fstab and I realize it had not ran in a while. I checked cron and there were no entries for it. I got to wondering if I should ever be worried about a cron update coming down and over-writing my existing cron file with the backup entries in it to run.

We are seeing some strange behavior on a Set top Box with the scheduling of tasks. We use 2.6.12 kernel. The issue is when we create a Task, say task1 with a priority of 46.But,this task is not Scheduled to run by the scheduler right away. It gets chance to run only after sometime. What we see here is that I create many other tasks with lower priority than task1,but they are immediately scheduled. Ideally, the task1 should have got scheduled before certain other low priority tasks as it has higher priority. Any patch is available wrt this?
