I want to add two separate tasks/jobs to Cron that needs to run every 10 minutes, but I would like the second job to kick off only 5 minutes after the first job. Is there any way this could be done within Cron?
View 2 RepliesI 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.)
I have this in my crontab (along with another line before it):
Code:
* * * * * /bin/echo "Does this work?" > ~/test
...and the file doesn't show up. I have a blank line after that one in the crontab. I have no /etc/cron.allow or /etc/cron.deny files. I'm running Ubuntu 11.04. /var/log/syslog shows "BEGIN EDIT" and "END EDIT" etc. when I run crontab -e, but doesn't say anything about trying to run commands. Anything I might be missing?
i need to know how to set cron jobs up for programs like eggdrop and psybnc
View 1 Replies View RelatedI have a cron job that executes fine in opensuse 11.4. It is located in
/etc/cron.d/publish.cron:
jpablo /srv/django-apps/smcommand/scripts/publish.sh
It is correct, I want it to execute every minute. Now, I copied the same script to ubuntu maverick, and it doesn't run. Perhaps there's some ubuntu peculiarity that I'm not aware of?
Basically what I wanted to know is, if we turn the computer off (or hibernate/standby) - what will cron do with the tasks that were suppose to be scheduled during that time period the moment u turn it back on? Reason I ask is because i have a backup scheduled for every single hour. And another one I want to schedule for every 15mins. If I turn my comp in standby overnite, I certainly don't want to turn it on in the morning to find cron doing like 30 back up jobs!
View 2 Replies View RelatedI am running a series of operations on executable matlab scripts which are connecting python and fortran scripts. I schedule the executables in cron. The problem:
- My original matlab scripts work perfectly.
- My executables work perfectly if I run them from the terminal. - Using the gui scheduled tasks and running the scripts once from a button, everything also works fine.
- But when I leave the scheduled tasks run on their own, I get an error! The error can be that the script hangs in general (I have some text logs exported every step to track the progress), or I get an error which never appears when I run the script with any of the other mentioned ways.
- I tried both cron command prompt or the GUI scheduled tasks
- I am running on Ubuntu 64 bit
For some reason my cron jobs are not running and I can't seem to figure out why.
Here is crontab -l
Code:
SHELL=/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin

I use crontab for a daily alarm clock, which stopped working after I moved to Lucid.
Code:
$ crontab -l
# m h dom mon dow command

View 3 Replies View RelatedI am running Ubuntu 10.10 on a new Dell PowerEdge.
I built the system ~2 months ago and have successfully been running a list of cronjobs.
The jobs last ran on 5/31/11 at 7:35am. Since then none of the jobs have run.
I see "cron" in the process list when I run ps.
Got a small problem, I'm trying to schedule a script to run every Thursday at midday and the scheduled tasks application on Ubuntu doesn't seem to work. The script is fine when I run it from a terminal.I have zero experience using cron at the command line, can anyone tell me what I should do?

Have a headless server running Lucid 64 bit. Everything is working great except for a couple of Cron jos I'm trying to have run at boot.
My user crontab looks like this:

@reboot /usr/bin/SpiderOak --headless &The SambaBkup script works like clockwork...
The SpiderOak job doesn't start. It works if I type the command in manually.
syslog only shows:Jul 13 22:45:33 RavenWing cron[1010]: (CRON) INFO (pidfile fd = 3)

I recently set up exim so that I could test emails sent from my php sites. I have now been getting daily emails that either report errors from cron jobs or report a failure to send emails to root@cory-laptop or cory@cory-laptop about cron errors.I first of all don't want mail sent to the above addresses, because they are obviously not actual email addresses. Second, I'd really prefer not to get emails when an email failed to send to these addresses.

View 4 Replies View RelatedI have a file server that is an NIS client. User home directories are auto-mounted from another server. Users are not able to run cron jobs. The /var/log/cron logs says:
Jan 6 14:33:01 inclination crond[3217]: (username) ORPHAN (no passwd entry)
I tried adding an entry in /etc/passwd, /etc/group, and /etc/shadow but the test script I have still doesn't seem to run although cron thinks it did. The log entry for these attempts looks like:
Jan 6 15:30:01 inclination crond[4312]: (username) CMD (/home/username/test-script)
Now root does seem to be able to run cron jobs with no problem. My test script works fine from cron when runs as root. I suspect there's an issue with how I have NIS configured but I can't find any info. The test script runs fine from the command line when logged in as myself.

View 1 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 RelatedJust curious if this is possible. What I want to do is setup a rsync job to backup my laptop to my personal file server(same LAN), but I want it do do this at 3AM while I'm sleeping. However I always close my laptop lid when I'm done using it which puts the laptop into suspend mode since that's how I configured my power options in gnome. Since I don't want to leave my laptop powered up all the time, I was wondering if it is possible to have a cron job scheduled that will wake the laptop up(out of suspend mode) and run my script/backup job, all without opening the lid of the laptop, and then put it back into suspend mode when it's done. Is this possible, and is it as easy as scheduling a cron job or is there some other scripting/configuration/trickery that I need to do to accomplish this?
Also, my laptop's BIOS has the option to power on at a scheduled time if needed, but I'm not sure if that would work with it being suspended(hibernation is not an option since my entire HD is encrypted with LUKS and I would have to be present to enter the password to boot the system.).
I have a XEN DomU VM running Lenny and set up using debootstrap. I also have the TimeWentBackwards issue sorted using: [URL]. The problem is that my cron jobs just don't run. I've set up a cron job that simply echoes a date string to a file as a tester but it's not running. I've tried it under the root crontab, in /etc/crontab and set up in /etc/cron.daily. Is there something I'm missing?
