Software :: Script Not Running Via Crontab, Run's Fine Manually?
Feb 8, 2010
Yes I have tried exporting my paths and variables aab still will not run my script. 'm sure I am doing something wrong.I have a shell script which runs a jar file. This is not working correctly. After reading around I have read this is commonly due to incorrect paths due to cron running via it's own shell instance and therefore does not have the same preferences setup as my profile does.here is what my script looks like today after several modifications:
I have written a simple backup script, and added it to CronTab, but it doesnt execute at all. Here is my script: [URL]...And my CronTab entry: 0 */2 * * * root /home/server/Scripts/backup.sh
I want to start out by saying that I've search for this problem but none of those solutions where of any relevance to me/didn't work.I have this bash script I want to run in crontab that will check my /dev/md0 for failed devices (I dont want sendmail or postfix for this). The script won't run if not run manually. Does anyone see a problem with the script or crontab? Is it even possible?
Here's /etc/crontab: 0 12 * * * /bin/sh /checkRAID.sh I have also tried
I use crontab to execute a bash script every minute and the output is redirected to a log file.In that bash script there is a screen command to start a screen session.When I execute the script manually it works perfect, but with crontab, the screen command is not executed, but the echo's are. Because they are written in the log file...Here's my script:Script removed for violation of LQ Ruleso the script runs perfect when I do it manually, but not with cron...Here's my crontab (sudo crontab -e)
# m h dom mon dow command */1 * * * * sudo /home/laurent/Games/Cod4/StartCod4.sh | egrep 'running|started' >> /home/laurent/Games/Cod4/Serverlog.log
I am using Linux 64 bit Redhat Linux. I am trying to setup simple crontab as follow...1. Edited crontab file using crontab -e2. Listed the file once to verify it using crontab -l. This will display as.. 18 5 * * 2-3 ksh $HOME/testScript.sh > $HOME/testscript.out3. Logged in a root and restarted cron deamon using "/etc/init.d/crond restart"As per my understanding now my testScript should start running at 5:18 am Thuesday
I have a problem using crontab. I have a C file which invokes a linux command. I want to execute the file using crontab. Its like whenever the system boots up and contents gets loads i want to execute this script. The problem is I don't know how to run the script using crontab. For eg if the file is present under /home/user/first.c . In order to execute this script whenever system starts wat wil be my command
I opened "crontab -e" in the Terminal and in nano I copied and pasted the first line of this copied script, leaving all the notated lines out. Each time I manually run changer by clicking and selecting "Run" it changes my Wallpaper but this does not happen automatically no matter how many times I reboot.
None of these jobs is apparently running, however they did run on the 31st (yesterday), but not on the 30th or any other day during the last 10 days that I have logs for. I think I've set cron to run at log level 1, but I don't know where that log goes, I don't see anything like /var/log/cron
So, couple questions: * If I do something like "sudo -s" to get a root prompt and then do a "crontab -e", which user does that crontab get executed as? * Where should I look for cron logs? * Anyone know why a job would run on the 31st, but not any other day?
Im new to linux, using ubuntu 10.04. I have been playing around with crontab and have no problems scheduling a job which runs a script file containing the following command:
However, when I try to do the following in the script file nothing happens..
Similarly the following doesnt do anything either:
I'm trying to get myself familiar with bash scripting.I created a script to delete all files and folders in a specific directory, and made an entry in crontab.Crontab will not run the script, but I can run it manually.
Cron seems to be running the script below (According to /var/log/syslog) but I'm not receiving the email it should send. This does work when I invoke it manually. checkraid (-rwxr-xr-x 1 root root)
Code: #!/bin/bash echo `/sbin/dmraid -s > /etc/check-raid/check_state` index=0 while read line; do
I am having a shell script which runs perl jobs.The script is starting the perl jobs when it is executed manually from the command line , but when the same script runs from crontab it is not starting the perl jobs.I have these things in the begining of the script
I'm using crontab to start and stop music playback (its like start and end of a brake in school). The problem is that some of the entries should be run on even weeks and some on odd. exp:
This should be played on even weeks 00 08 * * * audacious -p 10 08 * * * audacious -u and this on odd 05 08 * * * audacious -p 15 08 * * * audacious -u
There are about 20 entries for even and 20 for odd. I found here on the forum that maybe this should work but for it is not working for me 00 08 * * * [[ $(expr `date +\%W` \% 2) = 0 ]] && audacious -p If I put it like that its not working at all
I am planning on running a script once every five minutes, and the syntax that comes to mind in doing this is the following:
Code: 5 10 15 20 25 30 35 40 45 50 55 * * * * /apps/<script>.pl Is there a better syntax to use to accomplish this task, or is the above example the way to go?

I have a shell script which is configured for the user. The main task of the shell script is to email certain user with a particular result.
The shell script runs perfectly when run from a Konsole terminal and configured through a crontab generates empty entries.
Below is my crontab for my user.
Code: # DO NOT EDIT THIS FILE - edit the master and reinstall. # (/tmp/crontab.XXXXSyNyp1 installed on Wed Jan 6 09:14:14 2010) # (Cron version V5.0 -- $Id: crontab.c,v 1.12 2004/01/23 18:56:42 vixie Exp $) #!/bin/bash
I have installed ubuntu 9.10 server with LAMP and SAMBA I have also added FMS (Flash Media Server). LAMP and SAMBA are running fine but FMS doesn't have all its functionality, it cant stream rttp.I have read that their may be a port/ip conflict between apache and fms but was wondering if anyone else had the same issues as me. I have also installed FMS with apache2 on my XP laptop to get the httpd.conf file and see how its set up, here it is.FMS / APACHE2 XP
Code: # # This is the main Apache server configuration file. It contains the
I found it once on the web by means of googling it.How do you run a command, from nrpe.cfg, to make sure that it works?For instance, command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
have a web application that runs fine.Whenever I run jetty manually the application runs ok. This is what I do:sudo java -jar start.jarThe application is located within the webapps directory correctly and the required jar files are within /usr/share/jetty/lib.But when I run jetty as a service:sudo service jetty startThe server starts, but the application does not respond. There is no error in the output. This is very strange, isn't it
I have a PGP script that for whatever reason if I let linux's cron run it automatically, it sends out the final email with attachment with a blank file. If I come in and run in manually everything works fine and the file is populated in the file. So the only real difference is that i'm running it manually through cron, rather than letting cron run it at a set time.Below is a sumary of my script.
is it possible disabling a crontab job without deleting the crontab description entry (by crontab -e)?I could also accept to change the entry itself. Now it's:0 0 * * 0-6 /home/me/cron/script.csh
I 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)
I have installed an application manager(monitoring application) on my linux server. Now, i need to have backup schedule for my application. The application itself has executive file to backup database.But when i put this file in my crontab to schedule the backup program it wont run!50 09 * * * root /opt/ME/AppManager9/bin/BackupMysqlDB.sh
