General :: Cron Job Not Running / Possible Reasons For This?
Oct 15, 2009
I have 3 cronjobs set up on my Unix server . Out of which 2 cron jobs run the same script but at different times and the other one runs another script.
So in the 2 jobs which are set to run PMDaily.sh for eg , One runs on Sunday at 8AM and the other runs monday to friday at 6 AM . How ever the Sunday cronjob works (runs through the crontab) but the Cron job set for Monday to Friday is not working. However manually if i run this script it workd perfectly.
Please let me know what could be the possible reasons for this?
I've setup a git-svn repo with cron to fetch from the svn repo daily. I have a script to do the fetching, and this is what is invoked by cron. Everything is fine with the repo, and the script works fine when executed manually. However, when it runs under cron, empty files get dropped into the .git directory. The files have names that look like they are some base64 output, e.g. juTrvjP6m8 and kcKf3hu3b4. Two of these files show up for every cron run. I thought these might be commit hashes, but they're not, git-show says it's an unknown revision. I set-up the repo as follows:
[code]...
The last line pushes the repo to a separate (bare) public repo from which others can clone. I'm piping the output from the cron job to a file, which looks like this:
[code]...
The line "fatal: unable to run 'git-svn'" is alarming, but the fetch seems to go ahead anyway. Where are these empty garbage files coming from, and how to stop them? Am I in for bigger problems in the future?
I've been having a bit of trouble running a shell script with cron. A friend of mine does a community radio show and the station has a live stream but no podcasts, so I've set up a script to record the stream and encode it as an mp3 while I'm away using mplayer and lame -that's what I'm trying to do anyway.
Here's the script, but it doesn't seem to run- at least, I don't see any of the files it should be outputing, would they be in the cron.weekly directory (where I have the script) or in my home directory?
#This is a script to record 'The Unnamed Show'
#it will record the show from the live stream, then convert the output #to an MP3
#Finally, it will delete any files no longer required HOME=/home/byron/
I have two custom tasks running daily. How do you give priority to one over the other?One of them is configured via the logrotate.conf. The other sits directly in cron.daily.I'd like the one in cron.daily to run after the script that is in logrotate.Please can you advise how to do this...
My root Vixie cron crontab is set to perform a system snapshot via fsarchiver: 0 0 * * * fsarchiver savefs -o -A /backups/p30_root.fsa /dev/sda2 /dev/sda3 The command itself works fine, generating about a 7G snapshot of my Suse server. I then wish to rsync this to a NAS I have located in another building: 0 3 * * * rsync -av -e ssh --delete /backups/ root{at address}:/DataVolume/os_backups/
(yes, I'm rsyncing as root. I absolutely loathe it, but I got thrown into an quasi-SA position with a ridiculous to-do list and no time to do it. I'm having to make things just work and then go back and try to improve them/learn how. I couldn't make it work in a non-root way quick enough, so for now I'm having to cron rsync jobs as root because of all the differing file permissions on this samba/MySql server. I set the NAS to only accepts ssh from the server IP, and we're behind a campus firewall... It's serious trial by fire.) The crontab also has rsync commands for the samba areas, our specialized chemistry software and affiliated MySQL databases............
I have NFS fileserver that has served me well for more than year. But recently I noticed that it has started to reboot on its own very frequently, almost once a day! It is most likely not a power related issue as I tried changing UPS/power sources, but no help!So my question is:Is there any log file where I can check which is causing the reboot? There may not be a single logfile, but I need some point to start the investigation!
My suspend-to-disk and suspend-to-RAM stopped working months ago. I've grasped at straws about why ever since, but I really don't think it's a software problem, because I've reinstalled my system (MEPIS) repeatedly. What sort of hardware failures could cause this? What should I be looking for? I notice that at boot, Linux always says "no resume image found," even if I left the system in suspension or hibernation. I can post parts of the dmesg if someone tells me what to look for; I can't display the whole thing because it's too long to fit here.
I am still an openSUSE noob and have been struggeling to get cron jobs running for the past couple of hours...without having success Hopefully a more experienced user can give me a hand As root I used crontab to setup some cron jobs:
Code: crontab -u api-cebian -e The resulting cronjob looks like this:
why my second cron job isn't running? The first one runs fine but the second one does not run at all. If I manually run the script using ./check.sh then it does what it is supposed to but will not run from cron. It should run every weekday at 9:45am, it looks good to me but clearly I am doing something wrong.
Code: # m h dom mon dow command #This will backup my hosted websites. 0 2 * * * /home/bob/scripts/websitebakscript.sh #This will run check and upload it's contents to the net. 45 9 * * 1,2,3,4,5 /home/bob/scripts/check.sh
Cron refuses to work for a newbie.I am trying to setup a cron job to backup a folder in my home directory ('/home/scratch') to a folder ('home/internet_backup') that is mounted (using nfs) to a network folder.the folder ('home/internet_backup') is mounted correctly to the network folder upon system startup, so this part works.
When I refresh the page 'updatestatistics.php' in my webbrowser it does generate a new page ('statistics.html', which is included in 'statistics.php'). But when I let this cron job do the job, nothing happens. I looked into the log file, it shows this:
After saving a few sample scripts in crontab, I discovered that cron is not running properly on my Ubuntu 9.10 (32 bit), after a recent reinstallation. Please note that the files "/var/log/cron" and "/etc/defaults/rc.conf" are empty in my system.
I want to make a cron job for my webserver, only it seems not to work...
I have now the followig to test (every 16th minute of the hour, write test to a file), but it doesn't show up. When I write out the cron, it is done to the file: /tmp/crontab.QXsBIO/crontab . How to make cron work? It must be very easy, but I have real troubles getting it fired up.
My Linux version is debian lenny and the cron file looks like (crontab -e):
I have created a conjob via ssh by going to crontab -e and adding my scripts like 05 10 * * * /scripts/old-files-delete.sh.The file has 755 permissions and if I run the script manualy it works fine. I have checked the cron log and it does not show up as running at all.
I have a cron job set up to backup my ~/ directory everyday at 10:00. But the cron job is not running. here is my confile that I loaded into crontab...
Code:
#backup everyday @ 10:00 AM and 10:30 AM 00 10 * * * /home/dave/bin/backup.sh 30 10 * * * /home/dave/bin/music_backup.sh
[code]....
the *.sh are executable. I logged out and logged back in since I put the cronfile in crontab. The commands that I use in the *.sh files work fine when I run them manually.
I seem to be having a problem with cron. I have a python program that checks a specific directory for pending email scripts written in python.
Code: #!/usr/bin/python import os emaildir = os.environ['HOME']+"/email/" filelist = os.listdir(emaildir) for pyfile in filelist: if pyfile.find(".py") > -1: execfile(emaildir+pyfile)
This code has been tested and works fine. The problem is that I need cron to run this code every 5 minutes but i can't tell if it is running: Here is my cron code: 5 * * * * /home/username/custom/CheckEmail.py >>/home/username/custom/email.log 2>&1
I activated the log (I think) but all i get is /var/log/cron.log and that only logs when I activate/deactivate or edit the cron file. is there anything else i need to set for this to work? I am running Ubuntu 9.10.
I still can't figure out why my cron job isn't working. I'm sure I'm missing something obvious, but it's got me beat
I know cron is executing my script (I had it echo some lines to a file at points within the script, and that text showed up, but none of the files/folders are being copied or removed)
crontab looks like this:
Code: PATH=/usr/sbin:/usr/bin:/sbin/bin #m h dom mon dow command */20 * * * * /scripts/scriptname
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?
I have an external usb hard drive that spins down every 10 min. The commands in 'hdparm' do nothing to override the internal settings. So, I wrote a script to touch a file every 5 minutes, and it will run as root because of the mount command, and I want it to run for every user. The script is executable, owned by root, and root is the group, with 755 permissions.
no_sleep.sh in /usr/sbin:
Code: #!/bin/bash # Script to keep external drive from spinning down diskmounted=$(mount | grep Backup | wc -c)
after that wait till that time but script is giving message no such file in directory but same thing is excute manually it is running fine and found the files. Below is my script details file name ejrename.sh. code...
Im having some difficulties with running a shell script from cron which I am unable to resolve for almost 2 days now.
For testing purposes, im trying this with simple shell script test.sh with chmod 777
This script is located at /var When I type /var/test.sh it runs perfectly and prints asdasdasd When I type /var/test.sh > /home/log it writes asdasdasd to /home/log - works
The problem occurs whenever I add it as a cron job to var/spool/cron/crontab/root
There is: 11 10 * * * /var/test.sh > /home/log - however, at 10:11 there is no file at /home/log
Cron as a service works, forexample, every day at 4 am it makes this backup sshpass -p xxxx rsync -avz -e ssh root@x.x.10.7:/data/backup/ /home/backups/isp_admin
I am using Shell Script to run my Java program. I have written a Cron job to invoke Shell Script every day at 7pm. Cron job is running every day at 7pm ,but it is not invoking my shellscript and also I am not getting any error message. I am able to run same shell script from cmd propmt using bash, and also I am able to invoke the same script from mainframes Universal command job. Same ShellScript and Same cronjob is working fine in my Dev server. But in my QA server it is not working.
My focus is on the three WGET commands. The problem is the first one works fine, runs at 4:20 p.m., but the other two never run! If I visit [URL] it works fine but cron never runs it.
