General :: Crontab Not Working \ Edited Crontab File Using Crontab -e?
Apr 27, 2010
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
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 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
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 been having trouble setting up a daily backup script with cron. It would basically never worked. Searched the net for answers but didn't find anything. I finally figured it out !! When root crontab is edited the execute flag is removed from #/var/spool/cron/crontabs/root. I change it with #chmod a+x /var/spool/cron/crontabs/root and all is good.
I'm running Ubuntu server 8.04.3 with eBox on a Dell GX280. I want to power off my box automatically every night, so as root I added a crontab entry "05 1 * * * /sbin/shutdown -P now". The command runs on schedule but most days the PC goes into a coma instead of powering off. It doesn't respond to key presses or mouse movement or Ctrl-Alt-Delete, I have to push its power button to complete the shutdown. I have tried a variety of alternatives such as "/sbin/shutdown -h" and "runlevel 0", they all behave the same way
i want to do scheduling using /etc/crontab file instead of using crontab -e that is crontab command on the terminal.i am appending to the crontab file in the /etc directory but the scheduling is not happening
I attempted to run various cron jobs as root - just general server make-tidy stuff. But if I edit the /etc/crontab file directly, these tasks don't get run. However, if I use crontab -e as root, these jobs appear to work. Any idea why this might be the case? Also, I understand that user cron jobs are stored in /var/spool/cron/<user> (including root). If this is the case, what's the purpose of the /etc/crontab file?
I've tried to create a crontab that renames a fil extension every minute. This is what I've tried:*/1 * * * * / rename /home/bodil/Avräkningsfiler/'s/.txt/dat/' *.txtBut it doesn't seem to work.I've also tried to create a .sh file in the catalog itself with the command executing directly in the catalog but even though running the command by typing it in, it doesn't run automatically by cron
I have this code that is 'bashed' regularly with crontab and basically it will send me an E-Mail of most of the output but it misses out some of it!
Here is the crontab code to automatically run the script:
Code:
So that sends me an E-mail with most of the output of the following code:
Code:
It sends me everything up to echo "*******" "Begin compressing and transferring files" "*******" but it wont output the tar bit.. so it should give me a list of files that have been tarred.
I am trying to have the files from /user/directory copy every hour to /backup/user/directory. It would seem that cron or crontab is what I need to use. Looking at previous posts and other documentation only shows how much I don't know. When I type crontab -e I get a blank file I can type into, seemingly using vi as the editor. I have no problem with that but when I type cron -l, I get my text after a message about "Do Not Edit this File". What I am reading just makes no sense, I am not understanding even the most fundamental aspects of cron or crontab. Where I can get the most basic of basic instructions to try to understand this function?
Is been a while since I was last here requesting help. Now I need some of that LQ magic. I have a script file that extracts data for a date range, create a zip file for the data and then ftp it to a remote server. Now the script is working perfectly if it is run manually, but now I want it to execute automatically. So I use the crontab, but for some reason the script fails when run from the crontab.code...
when a script in /etc/cron.d directory will be executed?. I know that scripts in cron.daily will be executed daily [ set in /etc/crontab file]? Cant able to find this directory listed in /etc/crontab file?
No matter what I try I just cant get cron working for me on my Squeeze setup I can type /usr/bin/soffice and openoffice will fire up no problem but put into a crontab and nothing for instance just to test if crontab is working I have this/5 * * * * /usr/bin/sofficeIn y user crontab but nothing happens I have run as root crontab -u djt crontab And after editing the crontab with crontab -e it says it is installing crontab but it just does nothing Unfortunately I am connected to my works network so unable to receive internal mail from cron so cant find any reason for it not working
Have just started to use look at crontab. I could use Scheduled Tasks as well as crontab -e in terminal.
I must have changed something because now Scheduled Tasks just seems to load then dropout. Loading a task through terminal is accepten (crontab -e) but doesn't work.
I'm setting up a new server and have edited the crontab to a run a script but nothing is happening, is there anything I need to setup to get the crontab working?
A couple days ago I noticed cron stopped working and now I can't create a new file using crontab -e. When I hit crontab -e I get the editor but after saving nothing comes up under crontab -l and the file is blank when I reopen it. I don't have a cron.allow or a cron.deny.
I used crontab to set a file playing at a certain time, this works fine; however I want this to run even if no-one is logged in (but the computer is on). I can't get it to do this
Line is: 30 06 * * * env DISPLAY=:0.0 /usr/bin/totem /home/adunaic/Playlist.pls
Okay I think the problem was with needing a GUI.
Using this instead works, but i only hear the sound when I log in. I think something needs to be doen to start the audio perhaps?
I am trying to run rsnapshot from cron via root's crontab file (crontab -e). If I run rsnapshot from the command line with sudo it works perfectly, however, if I run it from cron:
Code: * * * * * /usr/bin/rsnapshot hourly >/tmp/crontab.out 2>/tmp/crontab.err This does not work. The crontab.err file shows:
I am using squid 2.6 on my cent os 5 .I want to shutdown the system at 7:00 pm for that purpose I write in# crontab -e 0 19 * * * /sbin/shutdown -h nowThe thing which I want to clear that when the system will going to turn off it will also stop squid service? If not then how can I automatically stop squid service and then crontab file execute
I use the following code to send make-up file dialy via sftp with expect. When I run it from command line, it has no problem sending to the remoteSERVER side, but when it is running via crontab task, it did not do the put, so did not execute the batch file defined in -b option.
