I know crontab -e sets a cronjob in /var/spool/cron but how do I set a cronjob to run from /etc/crontab? Is there a command used for this or would I have to manually edit a certain file?

View 1 Replies View RelatedI'm working on a bash script that will be run regularly via a cronjob. As there is no easy way for the user to see if it's running in the background, I'd like a have some kind of pop up window what say's something like "Process started" and "Process finished" when it's complete. Ive read though some similar threads and came across xmessage. It kind of does what I want, with the exception of:-Id like the message Process started to stay up for the whole process, but it looks like the script wont continue until the xmessage window is closed. I cant get any xmessages to appear when the script is run from a cronjob. It only appears if I run the script manually from a terminal window. Which is no good for me. If anyone has any suggestions that would be great and just to add, it's doesn't have to be xmessage, any text box would do. I'm working with Redhat 4 and 5, if that makes a difference. Chuck Norris destroyed the periodic table, because he only recognises the element of surprise.

Currently we have to comment out an rsync task every now and then. Is there a way to have a PHP script on the server so we can simply browse to it to uncomment the rsync task and another one to comment it out again ?
The rsync job is the only job in crontab so even if it means deleting / re-creating the job wouldn't be a problem. I just want to avoid connecting via SSH and VPN every time I am asked to disable it

View 2 Replies View RelatedI wrote this little script and it runs very well, however when I setup a cronjob it only runs if I am logged in. I would like to have this script running even when I am not logged in. At the moment it runs but only when I am logged in.

I am a PHP developer.I have always used XAAMP(in Windows7) for development purpose. I am driven to turn to Linux now . I have installed Ubuntu10.04-rev189(Wubi) in Windows7 recently. I have a PHP script which require the following tasks to be performed.
1. Give permissions "777" to the following files and folders:_cache media images /configs.php mages/config_photo_preview.jpg
2. Set up cron jobs on your site like this: /usr/local/bin/php -q /your-site-root-dir/cron/index.php I need to get an environment like XAAMP and perform the above mentioned tasks.
i wanted to ask you for help in setting up a cronjob, that restarts a game server.By now I made a script that kills the screen of the server and then restarts it.

View 2 Replies View Relatedi have a site where I need to run a couple of php scripts every day..therefore I was thinking to setup a cronjob to do this. Unfortunately I get a whole bunch of errors trying to do so.
I can execute the php scripts via a command line without problem, one example would be
php /home/site/domains/stie.be/public_html/admin/cronjobs/cronjob_daily_ssh.php
however when i enter this command as such in a cronjob I get an error saying php command not found ( or something similar , doing this out of memory)
I tried to add the full path to the php command, but also this doenst work
the best workaround I found was to execute the php scripts with a lynx - dump command, but obviously this is not the right way.
I am new to bash scripting (not programming in general).
I am writing a bash script that will run a Python script I have written.
I want to be able to do the following:
Pass parameters to the bash script via the cronjob (so I can have two cron jobs) one to be run with parameter 'foobar', and the other 'foo'
switch based on the parameter passed to the bash script (by switching, I mean an if/else based on the paramter passed to the bash script).
I would like to make a cronjob who makes a tag.gz of everything inside a directory in a recursive way. BUT there is a HUGE directory full of jpg's. I don't want this one in the backup.Additional points if it can backup symbolic links.

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)

View 5 Replies View RelatedMy laptop's clock (Acer Extensa 5220) seems to be slow. I've corrected it 5 minutes forward last week and now have just corrected minute forward again. Is there a program [apart from time servers] to correct clock properly, for example, by shifting it a bit every hour? Is there already a program to put it to crontab or I should hack up a script? Or I should check more things?
I have found that HW clock is right, but system time is slow: about a second each 2.1 hours.

Is placing "hwlock --hctosys" to crontab a right thing?
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:
Is there something im missing?
Silly question here. My crontab looks like this:
Quote:
0 22 * * * /usr/sbin/logrotate /var/log/VRTSralus/VRTSralus.logrotate
#0-59/10 * * * * /root/memmon.sh >> /var/log/memmon.txt
0 8 * * 1 /root/SHC.sh
#0 21 * * * /root/scripts/ralus_restart.sh > /dev/null 2>&1
As you can see two of the lines are commented out. However, both commented out commands are still running. I get emails stating that the RALUS agent restarted (another mystery since it's supposed to go to dev null according to the line above), and I can see that the memmon script is also running daily. Am I missing a step? Some other place I should be looking? Commenting out lines in your crontab is pretty much a no-brainer, so I appear to have less than no brain as this is a mystery to me.
